The New Trek Émonda Is Faster Than Ever

Already one of the fiercest climbing bikes available, the new Émonda is even faster thanks to a dose of aero.

The Takeaway: The Émonda SLR is a benchmark pro race bike—and it’s surprisingly rider friendly.

• It has 183 grams less drag than the previous generation, but the frame is only 33 grams heavier
• There are 10 models starting at $2,699
• SL models ($2,699 to $5,999) have the aerodynamic shaping and features but in a frame that’s about 400 grams heavier than the SLR
• SLR models ($6,699 and up) use a new carbon fiber composite that’s 30 percent stronger than Trek’s previous top-of-the-line carbon.

For Émonda SLR bicycles, Trek will provide an individual handlebar and stem until an updated handlebar/stem combo is available.

Additionally, all customers who bring in their handlebars for replacement will also receive a $100 in-store credit that can be used toward any Trek or Bontrager merchandise through December 31, 2022.

Remember professional road racing ? It’s that thing where super skinny people go unbelievably fast up and down hills and fly over flat roads for hours at a time. It’s been a while since the pros have beat up on each other for our entertainment, but there might, hopefully, be some races on the horizon. When the races do resume, Trek’s pro riders will be aboard its new third-generation Émonda climbing bike. The new Émonda isn’t lighter, but it is faster thanks to a dose of aerodynamic tuning.

Now With Aero

The new Émonda gets a major drag reduction with a tiny weight gain.

Simple Seat Mast

The seat mast has lots of adjustment range, and an easy-to-use saddle clamp.

Light and Slippery

The new Bontrager Aeolus RSL 37 wheels are light, sleek, and stable.

Wide and Threaded

The T47 bottom bracket has a wide stance, and user-friendly threads.

A built-in chain watcher prevents unwanted derailments.

Making the new Émonda frame more aerodynamic wasn’t exactly a tough hurdle as the previous Émonda had virtually zero aerodynamic optimization. But adding meaningful aerodynamic benefit while achieving the frame stiffness expected of a pro-caliber race bike, maintaining the well-regarded handling properties of the previous Émonda, and adding rider-friendly features like a threaded bottom bracket—all with adding only 33 grams (SLR frame, claimed)—is quite a feat.

Below you’ll find my review of the Émonda SLR—I’ve been on it since early March—followed by a dive into the technology and features of the new bike, and a brief model breakdown.

Ride Impressions: Émonda SLR 9 eTap

The Émonda SLR is a tool made to fulfill the needs of some of the world’s best road racers. This bike will never be as comfortable or versatile as a gravel bike. Going fast on pavement and climbing performance are its only goals. These are obvious facts, but that’s the lens through which it must be viewed. And through this lens, it is one of the very best.

The new Émonda was born out of a request from Trek’s pro racers and pitched as the company’s “fastest climbing bike ever.” So little surprise they set me up with the lightest model (the SLR 9 with SRAM Red eTap ), which also has a build kit almost identical to the team’s bikes. It’s also, excepting customized Project One builds, the most expensive model at a buck under 12 grand.

That massive pile of clams gets you an aerodynamic frame with disc brakes, power meter, and wireless electronic shifting that weighs less than 15 pounds (54cm). And that’s with a hefty T47 threaded bottom bracket unit, lustrous paint , clincher wheelset, a chain-watcher, standard butyl tubes, 37mm deep rims, 160mm disc rotors front and rear, and SRAM’s largest Red cassette (10-33). That’s “Holy shit!” impressive.

By cutting drag a ton without adding much weight, it’s hard to argue with Trek’s claim that the new Émonda is faster than the outgoing generation. But if you have any doubts, they’ll be erased when you ride it. This is an explosive bike: it feels as light as a feather and as solid as a steel girder at the same time.

Trek’s Émonda has always been a raw and rowdy bike that feels a little wild and a bit dangerous in precisely the ways you want a race bike to feel: That’s not lost with the added aerodynamics. If anything, the new Émonda is even crisper and punchier than before, which is saying something.

A small downside to all this fury is the Émonda’s smoothness. Light and stiff race bikes aren’t a smooth-riding lot to begin with, but even measured against a stiffer riding genre, the new Émonda is on the firmer end of the scale. Still, it escapes harsh or punishing labels—I did a six-hour ride on the Émonda on the stock 25 tires and didn’t feel worn down by its ride. Swapping to 28s helped a lot (no surprise) and were on the Émonda for the bulk of my testing. I’d suggest reserving the lighter and more aerodynamic stock 25s for racing or PR attempts—assuming good roads—and use 28s as daily drivers.

The Émonda’s handling is excellent. Well, let me caveat that: Road racing geometry is pretty uniform, so whether I’m on a current race bike from Trek, Specialized, Cannondale, Cervélo, Canyon, Colnago, Wilier, Pinarello, BMC, Giant (etc., etc.), I find the broad strokes of their handling feel and performance quite similar. There wasn’t anything about the Émonda’s handling or cornering performance that set any new benchmarks for me, but there wasn’t anything to dislike either.

It was quick and accurate, diving into corners with a light touch. It offered great feedback, so I always knew where I was relative to its and my limits, and I could count on it to be consistent and predictable. It was maybe a touch less settled in bumpy corners than the Specialized Tarmac, but the Émonda never broke traction or skipped. Overall, for such a light bike, the Émonda is remarkably solid and drama free. I’d have no qualms barreling down a technical alpine descent on the Émonda.

I received this test bike in early March, giving me plenty of time to ride it back to back with its primary competition—a Specialized S-Works Tarmac , what I consider the benchmark for aero-ized lightweight bikes. The Tarmac is smoother over the bumps and has a silkier feel overall, but the new Émonda feels more efficient, like it can go faster more easily.

I’ve also ridden a good slice of the Émonda’s competition, including the Canyon Ultimate CF SLX , Colnago V3Rs, Cannondale SuperSix Evo , Cervélo R5, Wilier Zero SLR , Pinarello Dogma F12 . These are all superb bikes, but I feel the Émonda is the class leader. It feels sharper and more explosive than all of them. It feels faster, and that’s what matters most in a race bike. But I also like that the Émonda is pretty straightforward and rider-friendly.

For example, I swapped the stock one-piece bar/stem for a standard stem and round bar. One, I could run a standard bar and stem on this bike, which you can’t say about every modern race bike. And two, I didn’t have to pull any cables, wires, or hoses to make the swap: Again, something you can’t say about all race bikes. For the record, the shape of the one-piece Aeolus bar/stem is great, and the tops are the most comfortable to grab of all the aero-topped bars I've used. The only reason I swapped is my preferred length and width combination (110x40) wasn't available yet.

The BB is threaded, which makes it easier to service and replace than a press-fit (however, I was getting some noise out of the BB area, which I never resolved). The wheels employ standard offset, and it uses regular thru-axles. It’s compatible with pod-style power meters and mechanical shifting. Its signature seat mast is pretty much the only non-standard thing about this frame, and even then, it’s pretty user-friendly. There’s no cutting necessary, height adjustment is ample, the saddle clamp is easy to use, and it’s travel-case friendly.

I expect so much from a modern high-end pro-level road racing bike that it’s hard to exceed those expectations. It’s rare when a bike does: The Émonda SLR is one of those rare bikes.

Team Request

The new Émonda is partially a result of a request from the Trek-Segafredo race team. “They are one of our primary customers,” said Jordan Roessingh, Trek’s director of road product. “And they started to realize that it’s not just weight, it’s not just stiffness and responsiveness, there’s this other thing—aerodynamics and speed—that’s also really important to be competitive and be faster on the bike. They had been one of the loudest voices saying, ‘We need the lightest-weight, stiffest bike possible.’ And now they started coming back saying ‘We need those things, but we also need the bike to be faster in order for us to be really competitive.’ ”

It is (comparatively) easy to make a light frame, it is easy to make a stiff frame, it is easy to make an aerodynamic frame. Making a frame that’s two of those three things is more challenging: Making a bike more aerodynamic usually makes it heavier, making a bike lighter typically makes it less stiff, etc. Making a frame that is light AND stiff AND aerodynamic enough to satisfy the demands of a top-level professional race team is extremely difficult.

But not impossible. Many brands already make a light, stiff, and aero bike. The Specialized Tarmac is one, as are the Canyon Ultimate, the Cannondale SuperSix Evo, the Cervélo R5, the Wilier Zero SLR, the Pinarello F12, the Scott Addict, and the new Giant TCR . All of them seek to balance the three qualities—light, stiff, and aero—in the pursuit of the ideal race bike, and they all manage the balance differently. The common thread between these bikes: They’re all used by teams that compete against Trek-Segafredo.

Still Light, Now With Aero

The previous generation Émonda SLR Disc , launched in 2017, was an extremely light frame at 665 grams (claimed). But when a frame is already that light, it is much harder to make it even lighter. At least lighter enough to make a meaningful difference.

So, Trek took a different approach to making its climbing bike faster—instead of lighter, it made it more aerodynamic. The new Émonda frame is a touch heavier—yet still extremely light at 698 grams—but the bike has 183 grams less drag than the previous generation.

The important thing to note here is that, though the frame is more aerodynamic, the 183 gram drag reduction is not from the frame only. New wheels and a new aero bar (more info on both below) play a role. The specific setups Trek used to get that 183 gram number are: 2018 Émonda with 28mm-deep Bontrager XXX 2 wheels, and Bontrager XXX Bar/Stem Combo compared to the 2021 Émonda with 37mm deep Bontrager Aeolus RSL 37 Wheels and Bontrager Aeolus RSL Bar/Stem Combo.

Another drag saving upgrade: the housing, hoses and wires for the controls are almost fully inside the frame. They dive into the frame at the head tube passing through the upper headset bearing. The front brake hose runs into the fork steerer and down the left leg before popping out just above the brake caliper. The fork steerer’s flattened sides provide room for the rear brake hose and derailleur control lines to travel down and into the frame. Though it has flattened sides, the fork steerer is still compatible with standard 1 1/8” stems.

The overall drag reduction results in a bike that is 18 seconds per hour faster when climbing an 8.1 percent grade (the average grade of Alpe d’Huez ), and 60 seconds per hour faster on flat roads than the previous Émonda. Trek also claims the new Émonda is 13 seconds per hour faster than a Specialized Tarmac when climbing an 8.1 percent grade (all assuming the rider maintains a constant 350 watts).

Eight Point One Percent

With three qualities—aero, stiffness, weight—that work in opposition to each other, how do you decide how much to optimize one quality when you know it will negatively affect the other two? How aero is aero enough? At what point is improved aerodynamics offset by the weight added to get there?

The team behind the Émonda used a legendary climb to help them decide: Alpe d’Huez. “It represents an extreme example of what most people see on a regular basis when they’re doing a big climbing ride,” said Roessingh, “It’s around an 8 percent grade, and it’s about an hour-long climb for the pros—amateurs might go a little slower. It gives us a good understanding of what the benefit of a drag savings is relative to a weight savings.”

By optimizing the weight and aerodynamic balance around this climb, Roessingh claims the Émonda is faster on Alpe d’Huez and also faster on everything shallower than the famous climb, “which is the vast majority of the environments that most riders are going to ride in, including the team,” said Roessingh. “So if we can say it’s faster up Alpe d’Huez, it’s going to be significantly faster everywhere because the flatter it is, the more aerodynamics benefit you.”

Computer-Aided Optimization

Achieving the weight to the aerodynamic balance of the new Émonda required careful design of each tube shape. Aiding the Émonda’s team was supercomputing horsepower. The abridged and simplified version of the process goes like this: into the computer was fed a rough draft of the shape based on Trek’s aerodynamic experience and other information like UCI regulations. The program then varies the tube’s parameters within a predefined range and spit back several iterations of the shape, each with a different weight to aerodynamic balance. The Émonda’s team evaluated the alternatives and picked the one most suited to its location in the frame and best able to help the frame achieve its overarching goal.

Roessingh says that Trek cannot afford to buy the computing hardware necessary to run the CFD and FEA optimizations (in a timely manner) that helped shape the new Émonda’s tubes. The processing happens in the cloud where Trek rents time on Google, Microsoft, or Amazon’s supercomputers. It’s more affordable than buying a supercomputer. Even so, it is not cheap, “Cloud computing is becoming a relatively significant budget line item for us because we’re doing so many of these optimizations in CFD and FEA and all that processing happens in the cloud.”

The new Émonda’s fork legs, head tube, down tube, seat tube, and seat stays all use a variation of a truncated airfoil. The top tube and chainstays, which have virtually no effect on drag, are optimized almost entirely for stiffness to weight.

In Trek’s line, the new Émonda’s aerodynamic performance is equal to the third generation Domane ; the Madone is still significantly more aero. But while the more aerodynamic Madone is faster in flatter terrain, once the climb hits about 5.5 percent, the lighter Émonda becomes the faster bike. And for many of the Trek-Segafredo team riders—and many amateurs—that means the Émonda is fastest when it matters most: the hardest part of a race or ride, which is almost always on a steep climb.

OCLV 800 Carbon

Getting the new Émonda SLR to be as light as it is while adding aerodynamic shaping would not be possible without employing a new carbon-fiber composite, said Roessingh. The new OCLV 800 composite is 30 percent stronger than Trek’s previous top-of-the-line composite (OCLV 700). Because it is stronger, they can use less: By using OCLV 800, Trek’s team was able to make the Émonda SLR frame 60 grams lighter than if they used OCLV 700.

The Émonda SLR is very cool, but it’s also very expensive (bike prices start at $6,699). For the 99 percenters, there’s the Émonda SL (models start at $2,699).

The SL uses OCLV 500 composite, and the frame is quite a bit heavier than the SLR’s. The SL’s frame comes in at 1,142 grams, with a 380-gram fork (SLR fork weight: 365 grams).

But material (and weight) are the only difference between the SL and SLR.

Aeolus Bar Stem

While a ton of work made the Émonda’s frame tubes faster, a big chunk of the new bike’s drag savings comes from the one-piece Aeolus bar stem. It alone is responsible for 70 grams of the Émonda’s 183-gram drag reduction. This means that if a traditional stem and round bar are installed on the new Émonda, its drag advantage over the previous-generation bike drops to 113 grams. And it means that you can make any bike with a round bar and traditional stem significantly more aerodynamic by merely installing the Aeolus. Retail price is $650.

The integrated Aeolus is made of carbon-fiber composite, of course, with a claimed weight of 297 grams (42x120). It’s offered in 14 length and width combinations, from 44x120 to 38x80. Hoses, housing, and wires run externally for easier service and repairs, but in a groove that keeps them out of the wind. A bolt-on plate keeps the control lines tucked and organized where they turn off the bar tops to run in line with the stem.

The Aeolus employs a mount that works with Bontrager’s line of Blendr accessories for mounting computers and lights.

Aeolus 37 Wheels

Another new Bontrager product rolling out with the Émonda is the Aeolus 37 wheelset. It comes in two models: the Aeolus RSL 37 (1,325 grams/pair, $2,400) and the Aeolus Pro 37 (1,505 grams/pair, $1,300).

The RSL 37 is claimed to be lighter than Zipp’s 32mm-deep 202, yet more aerodynamic and more stable than Zipp’s 45mm-deep 303. Both wheels are disc brake only (only Center Lock interface), tubeless compatible, use DT-Swiss internals, have no rider weight limit, and come with a lifetime warranty.

Surprisingly Rider Friendly

Though the new Émonda is clean and integrated looking and uses high-performance standards, it is also remarkably rider-friendly. Cables, hoses, and housing run externally on the one-piece Aeolus bar/stem for easier repair and service (with one exception: wiring for a Shimano Di2 or Campagnolo EPS bar-end junction box runs partially inside the bar). If you prefer a more traditional cockpit, it can be run with a standard bar and stem with 1⅛-inch steerer clamp.

The bottom bracket uses the threaded T47 standard , which is compatible with almost all common crank-axle standards.

Front and rear thru-axles are standard 12x100 and 12x142mm, and the wheels employ a standard dish. The standard flat mounts for the brake calipers are compatible with 140, 160, or 180mm rotors.

Tire clearance is officially 28mm, but that’s with a ton of extra space. I fit 32mm tires in the Émonda with ease.

And though all models do use a seat mast, it’s a no-cut variety with lots of adjustment range.

H1.5 Geometry

Trek did offer its top-of-the-line race bikes in the aggressive H1 geometry for riders seeking an ultra-long and low geometry, or H2 which was an endurance fit. The new Émonda is offered only in H1.5, which splits the difference between H1 and H2. The result is pretty typical dimensions for a modern race bike—a 54cm Émonda H1’s geometry is remarkably similar to a 54cm Specialized Tarmac.

There are eight sizes starting at 47cm and topping out at 62cm.

There are 10 models of the new Émonda. SL models start at $2,699 and are priced up to $5,999. SLR models start at $6,699 and go up to $11,999.

Only SLR models come with the Aeolus integrated bar/stem stock; and only the Émonda SL 7 ($5,499) and up come with the Aeolus 37 wheelset.

The new Émonda is a disc brake-only platform.

Project One

The new Émonda is in Trek’s Project One paint and parts personalization program. If that’s not luxe enough for you, Trek’s Project One Ultimate program allows you to work with a designer to come up with a one-of-a-kind finish, and Trek will source any parts you want for your new bike.

Trek Émonda Bikes Compared: Which One to Choose?

CyclistsHub is supported by its readers. We may receive a commission if you buy products using our links.

In this article, I’ll help you navigate the Trek Émonda aero road bikes by comparing the Émonda SL 6 to SLR 9 .

You will also learn:

• Who are they best suited for?
• Why I think you shouldn’t buy Trek Émonda with SRAM groupset.
• And which model gives you the best value for your money?

KEY TAKEAWAY

Trek Émonda bikes are ideal for climbing and hilly terrain. They are the lightest bike family of all Trek road bikes . The models differ in components (e.g., electronic shifting) and frames. The more expensive ones are usually lighter and have a higher-grade carbon frame, but usually diminishing returns.

Let’s dive deeper to help make your decision easier.

This article compares Trek Émonda Gen 6 and 7. The main difference between Émonda Gen 6 and Gen 7 is that Gen 6 has IsoSpeed decoupler, while Gen 7 has IsoFlow.

Trek Émonda ALR 5 to SLR 9

The following table summarizes the main differences between all Émonda road bikes.

Émonda Pros & Cons Summary

I summarized the pros & cons of the Émonda series below.

Émonda Pros

• Lighter than Madone road bikes
• Aluminum and carbon models are available
• Relaxed geometry
• Availability in multiple sizes and colors
• Integrated cable routing
• Lifetime warranty

Émonda Cons

• Slower than Madone road bikes
• Narrow tire clearance (28mm)

Émonda Main Features

Let me now explain the most important features of the Trek Émonda aero bikes.

Frame and Geometry

The Émonda bikes are part of Trek’s road bike lineup . They’re made of aluminum or carbon .

The names of the bikes have abbreviations that refer to the type of material used for the frame:

• ALR  are  aluminum  frame bikes.
• SL are bikes with 500 series OCLV*  carbon (mid-range).
• SLR are bikes with 800 series OCLV carbon (high-end).

*OCLV carbon is Trek’s patented carbon fiber process ( learn more ).

ALR Émondas are great entry-level road bikes , thanks to their affordability. However, they are still a bit more expensive than less-known competitors.

SLs are the best mid-range option. They are slightly heavier than SLRs but about 25% cheaper.

And SLRs are ideal for people who have more money to spend and don’t want to compromise.

Most Émondas are available in 47-62 sizes and multiple colors giving you a wide range of options.

Their geometry is more relaxed than on other racing bikes, so you won’t experience as much strain on your lower back and neck. The following picture shows the comparison with Specialized Tarmac SL 7.

Weight & Aerodynamics

Trek Émonda frame weighs 760g in size 56. The highest-end Émonda even weighs below the UCI 6.8 kg limit. However, low weight is not everything. Stiffness and aerodynamics are also important.

Trek claims Émonda frames are also relatively stiff and aero (of course, less aero than Madone). They are 18 seconds per hour faster at 8% gradients. ( Source ) However, more information on the methodology is not available.

Émondas are so lightweight also due to the absence of an IsoSpeed decoupler that adds weight.

Wheels and Tires

On some Émonda models, the wheels may be different, but typically, they come with Bontrager Aeolus Pro 37 wheels.

Of course, the low-end models have cheaper aluminum wheels . Fortunately, all Émondas come with tubeless-ready wheels. But remember, the tires are clinchers. So, if you want tubeless tires, you have to buy them separately.

One of the things that surprised me is that the lower-end Émondas have 28mm tires, while the higher-end only have 25mm. Most road bikes these days (except for some aero bikes) have 28mm or 30mm tires.

Unfortunately, Émondas only have tire clearance for 28mm tires.

Unsurprisingly, the Émonda bikes have a 2X drivetrain, as is customary for road bikes.

Trek fits them with Shimano and SRAM groupsets, and the number in the bike name indicates the groupset.

• Models ending with 5 use Shimano  105  (R7000) groupset.
• Models ending with 6 use Shimano Ultegra , 105 Di2 (R7100) or SRAM Rival AXS groupsets.
• Models ending with 7 use Shimano Ultegra Di2 (R8100) or SRAM Force AXS groupsets.
• Models ending with 9 use Shimano Dura-Ace Di2 (R9200) or SRAM Red AXS groupsets.

Interestingly, the Émondas with SRAM are heavier than the Émondas of the same series with the Shimano groupset. In addition, those with Shimano are also cheaper.

This is somewhat strange because Shimano retail prices are higher than SRAM. That’s why I recommend choosing Trek bikes with Shimano groupsets unless you prefer SRAM.

TIP : You might also be interested in this comparison of Shimano vs. SRAM .

So, which Trek Émonda bike is the best?

If you’re considering buying an Émonda, I suggest a model with a Shimano groupset. They are lighter and less expensive than the equivalent SRAM models.

For better value, consider the Émonda SL. It’s around 30% cheaper than the SLR but offers almost the same performance. From all models, I believe the Émonda SL 6 Pro with the Shimano 105 Di2 is the best deal.

However, if you don’t want to compromise, go for the SLR, which is more expensive but lighter.

Trek Émonda FAQ

Trek Émonda bikes are for pro cyclists, competitive roadies, and enthusiast cyclists who want a lightweight road bike. They are ideal for hilly, mountainous terrain and short, medium, and long-distance rides.

The main difference between Émonda and Madone is that Émonda is a lightweight road bike, while Émonda is an aero road bike. For more detailed info, please check out my comparison of Émonda vs. Madone .

The main difference between Émonda and Domane is that Émonda is a lightweight aero road bike. Domane is an endurance road bike with wider tire clearance, also suitable for off-road adventures. Domane is somewhere between Émonda and Madone. Learn more in my Émonda vs. Domane comparison.

Trek Émonda SL 5 Disc

At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Good scores are more common than bad, because fortunately good products are more common than bad.

• Exceptional
• Not so good

Trek's Émonda SL 5 Disc is a solid all-round race bike offering great handling, a stiff platform for performance and a comfortable riding position, plus it's all wrapped up in a minimalistic, clean-looking package. This build isn't exactly lightweight though.

Trek launched this latest Émonda design last year, giving what has always been considered its lightweight climbing machine an aerodynamic makeover that takes it into what I consider quality all-rounder territory.

From a ride point of view, I can't fault it. It's firmer than a lot of carbon bikes on the market, and I kind of like that. Getting smashed about isn't fun, but neither is a bike that mutes all the signals from the road below. The Émonda balances this well.

Stand hard on the pedals for a climb or sprint and the bike feels tight everywhere, although most notably around the bottom bracket area. There is no flex anywhere, and it just eggs you on to keep hammering away when your legs are screaming to ease up.

Chubby chaser

The only downside is that this SL 5 build's weight can just take the shine off. This 56cm model weighs in at 9.16kg, which is on the beefy side for a near three-grand bike.

The SL 6 Pro I rode last year came with an Ultegra mechanical groupset and 35mm deep Bontrager Aeolus Elite carbon wheels, and weighed 8.23kg. It felt much nippier than the SL 5 when it matters.

As an experiment I switched the SL 5's wheels for a pair of 1,400g Scribe Élan Wide+ 42-D wheels I had on test, and that unlocked the Émonda's potential. I'm not saying you should go out and blow £1,190 on newwheels, just that you shouldn't be put off by the standard weight of the SL 5. It can be tweaked without spending a fortune in the future.

On all but the steepest of climbs though, the Émonda doesn't feel as heavy as the road.cc scales would suggest. It still feels nippy as you accelerate out of corners or crest those short power climbs, and it always seems to have an eagerness to keep rolling.

Right angles

The geometry helps too. This is a proper race bike with a steepish 73.5° head angle for quick steering, plus a short 151mm head tube to allow a low front end and a short wheelbase. At just 983mm, this certainly gives it a nimble and flickable feeling in the bends.

On the downhills I found I could let the Émonda go even when the road surface was less than perfect. It just feels really planted, and coupled with that firm frame passing through loads of feedback from the tyres, I left me feeling perfectly in tune with it.

The steering is on the fun side of neutral, and allows you to just point the handlebar and aim for the apex. The Émonda is also very responsive to slight changes in body position if you need to tweak your line or get yourself out of trouble. I found this out when riding somewhere I had never ridden before – a descent which was easily 40mph+ in sections.

The Trek just nailed it, even though I didn't know what was around the next corner. With less caution than I probably should use, I could throw the Émonda through the bends while constantly making little tweaks to my position to line it up for the next one.

The SL 5 is also a quality mile muncher. The firm ride didn't seem to fatigue my joints any sooner than normal, and although the position is racy, it isn't extreme either. I could ride on the hoods for hours without discomfort and made good use of the shallow drops too.

Frame and fork

As I mentioned earlier, the Émonda focuses more on aerodynamics now than ever before, but that doesn't mean it has become a rocket ship on the road. The Émonda is a climbing bike after all, so Trek's engineers have honed in on 'unsteady aerodynamics,' which they say give larger effects at lower speeds when ascending, rather than on curves for cutting through at high speeds in straight lines.

For starters the front end has been made as smooth as possible, with all cables and hoses directed through the head tube into the frame and fork, giving a very clean look. The head, down and top tube junction is large and beautifully sculpted for airflow too. As a whole the Trek has been optimised for 25mm tyres, although it will swallow 28mm with 6mm of space around the tyre.

The integrated spacer is designed to line up perfectly with the frame when the handlebar is pointed straight ahead, although it does limit how far the bar will turn in each direction. It can feel a bit daunting at first – I kept worrying I might not have enough lock to negotiate a tight turn at low speed.

It proved an unfounded worry though, and the only time I reached the turning limit was when trackstanding at the lights.

The top-end Émonda SLRs use a carbon fibre all-in-one handlebar and stem to take things even further, but there isn't the budget for that here.

As for the seatpost, Trek has decided to do things a little differently. The seat tube extends high, up past the top tube by some way. An external seat mast slides over the top and clamps into position, and the seat tube inside the mast allows a bit of flex, which aids comfort.

The top tube flares out at the seat tube junction, which I find I often rub my thighs against. I got around it by running the saddle 5mm further forward, but it's worth bearing in mind if you have large legs.

The frame and fork are created using Trek's 500 Series OCLV carbon fibre. It's a bit heavier than the new 800 Series found on the more expensive SLR range, but still gives a reasonable claimed weight of 1,142g for the frame and 380g for the fork. There are a massive eight sizes available, too, ranging from 47cm up to 62cm.

The Émonda range is now disc brake only, which means you're getting 12mm thru-axles and flat mounts for the disc calipers.

Trek has gone down the T47 bottom bracket route. Standard threaded bottom brackets have the bearing cups sitting outside the frame, which limits the width the bottom bracket shell can be without pushing the Q-factor (the distance between the pedals) too wide.

To allow a wider shell, which in turn lets the down tube, seat tube and chainstays all have larger joins for increased stiffness at this crucial point, many brands use press-fit cups. These sit inside the frame, allowing a wider shell while keeping the Q-factor the same. In the past there have been creaking and wear issues due to slack tolerances between the cups and the frame, though, so some people have fallen out of love with them.

The T47 is kind of the best of both worlds, as the bearings sit inside the frame but they are threaded into place rather than pressed. That gives a better (and easier) fit, but still allows for that wide bottom bracket shell.

To finish everything off, the SL 5 is available in two colours: this Quicksilver/Brushed Chrome, or Carbon Blue Smoke/Metallic Blue, which I reckon looks even better.

Finishing kit

The SL 5 is adorned with a Shimano 105 R7000 11 speed groupset, which cannot really be faulted, either from my own experience of riding it for thousands of miles on test bikes, or from Dave's in-depth review from a couple of years ago.

The gear shifting is precise and works well even under load – especially at the chainset – and the feel at the lever is practically the same as Ultegra R8000.

Trek has paired a 50/34t chainset with an 11-30t cassette, which gives a decent spread of gears for a bike with racing intentions. Crank length is determined by frame size, ranging from 165mm to 175mm.

Alongside the flat mount 105 calipers the SL 5 uses 160mm SM-RT70 rotors front and rear.

Stopping power is great, as is the modulation and control.

If you weren't aware, Trek's in-house kit and component brand is Bontrager, so it's no surprise to find this adorning the Émonda throughout. The Comp VR-C Road is a shallow drop bar with a compact design, making it usable for most riders regardless of flexibility.

There is nothing flash about it, but it is comfortable, has a decent length of central section for computer mounts or lights, and its aluminium construction is stiff enough for out-of-the-saddle efforts.

> road.cc Road Bike of the Year 2020/21

The Bontrager Elite Stem is another component that just gets on with its job. On the 56cm frame you get a 110mm, and it comes with Trek's Blendr compatibility.

This means you get a selection of mounts for various accessories, such as lights and computers, to sit out in front of the stem. On Trek's website it's £59.99 (£30 more than the handlebar), so it's certainly not a budget component.

The saddle is called the Verse Comp and it's a good 'un, at least for me. It's got a swoopy shape I found gave me plenty of different position options (I like to slide back to climb, for instance). It's 270mm long and 145mm wide (155mm on the smaller frames) with steel rails and a central cut-out. It's also compatible with Blendr accessories.

The frame itself is compatible with DuoTrap S, which is a Blutooth/ANT+ sensor which can send all sorts of data and works with Garmin, Bontrager, PowerTap and more, though the sensor is sold separately.

Wheels and tyres

As with the rest of the finishing kit, the wheels are Bontrager. Using their sealed alloy hubs mated to Paradigm SL rims, they have an internal width of 21mm and 24 spokes front and rear. As I mentioned earlier, they are a bit weighty, but they rode well enough throughout the test period, and I had no durability or trueness issues. They are tubeless ready for a bit of futureproofing.

> road.cc's Best Cycling Wheels of the Year 2020/21

I'm a fan of Bontrager's tyres. I've ridden a few, and was impressed when I tested the R3 Hard-Case Lite a couple of years back. The SL 5 uses the entry-level R1 Hard-Case Lite, and it's pretty good. With a 60tpi (threads per inch) casing it isn't the most supple, but it doesn't detract too much from the ride quality.

They roll pretty well too, and grip is more than adequate in both the wet and dry. More importantly though, considering the review period took in the end of winter, they seem robust and suffered no punctures.

Still, as with the wheels the SL 5 deserves better in the long term. If you want to keep things in the Bontrager family, those R3s mentioned retail for £42.99 now, or £52.99 if you want to go tubeless.

Bike prices are all over the place at the moment, and there have been some big jumps in Trek's line-up. That SL 6 Pro I reviewed was £3,350 in 2021, and it's now £3,900 with what looks to be the same build. The frameset has gone up from £2,200 to £2,700. Meanwhile this SL 5 has come through relatively unscathed at £2,750, up just £25 over last year's prices.

Around the time this Émonda was released, Specialized launched its new Tarmac SL 7 (I was lucky enough to review the S-Works model), and it's a similar sort of bike to the Trek. For 2022 Specialized has largely used SRAM components on its road bikes though, so there's no direct comparison with the SL 5.

However, the entry-level Tarmac SL 7 is the Comp model, which comes with a Rival eTap AXS electronic groupset and DT Swiss alloy shallow section wheels for £5,000, while Trek's SL 6 eTap comes with the same wireless groupset and the Bontrager 35mm deep carbon wheels for £4,300.

There is some tough opposition out there though, with Canyon's new Ultimate CF SL 7 Disc featuring a 105 groupset, a full aero carbon cockpit and a claimed weight of 8.2kg for just £2,149.

Giant's TCR Advanced Disc 2 doesn't quite have the aero attributes of the SL 5, but it is considered a very good lightweight all-round race bike. For £2,349 you are getting a 105 groupset, full carbon frameset and Giant's own alloy wheels.

The Émonda SL 5 is a great bike to ride, and that's down to the top-notch frame and fork paired to good quality finishing kit. True, the wheels and tyres can take the shine off of the performance a touch, but that is true of many entry-point bikes. This is a bike that will tackle any kind of topography or race and excel at it. The frameset is great and it's ripe for upgrades over time too.

The Émonda is a classic all-rounder, fun, fast and stiff, although this model isn't the lightest

Tell us what the bike is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about the bike?

Trek says, "Émonda SL 5 Disc is a lightweight carbon road bike with a balanced ride quality, superior handling characteristics and the added benefit of free speed thanks to aero tube shaping. It's a great choice for century rides on hilly terrain, windy flats and speedy descents."

I think the SL 5 is a classic all rounder.

Where does this model sit in the range? Tell us briefly about the cheaper options and the more expensive options

This SL 5 model kicks off the SL range, sitting just £25 above the price of the frameset. Going up through the models you find the SL 6 and SL 6 Pro (£3,400 and £3,900 respectively), the SL 6 eTap (£4,300) and the Ultegra mechanical SL 7 (£5,350). Finally you get to the 12-speed Ultegra Di2 SL 7 (£5,600) and the SL 7 eTap, which uses SRAM Force for £6,100.

Above the SL range is the SLR line up, and below you'll find the aluminium alloy range, the ALR.

Tell us about the build quality and finish of the frame and fork?

A high quality frame and fork. It feels great to ride and the paint finish is high end.

Tell us about the materials used in the frame and fork?

Frame: Ultralight 500 Series OCLV Carbon, Ride Tuned performance tube optimisation, tapered head tube, internal routing, DuoTrap S-compatible, flat-mount disc, 142x12 mm thru axle

Fork: Émonda SL full carbon, tapered carbon steerer, internal brake routing, flat-mount disc, 12x100 mm thru axle

Tell us about the geometry of the frame and fork?

With its steepish angles and short wheelbase, this sits very much in the race bike camp.

How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?

This 56cm model features a stack of 563mm and a reach of 391mm, which is fairly typical for a bike of this size with racing intentions.

Riding the bike

Was the bike comfortable to ride? Tell us how you felt about the ride quality.

It has a firmer ride than a lot of carbon frames, but personally I like that. It feels like a purposeful and aggressive frame without ever feeling harsh and uncomfortable.

Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?

Plenty of stiffness throughout, most notably at the bottom bracket junction.

How did the bike transfer power? Did it feel efficient?

It does feel efficient, especially considering its weight.

Was there any toe-clip overlap with the front wheel? If so was it a problem?

How would you describe the steering? Was it lively neutral or unresponsive? Responsive.

Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?

I found the handling quick with a degree of balance to it – it never feels twitchy.

Which components had the most effect (good or bad) on the bike's comfort? would you recommend any changes?

I liked the Bontrager saddle. I found it squidgy enough to absorb the bumps, without being so soft you find yourself bouncing around.

Which components had the most effect (good or bad) on the bike's stiffness? would you recommend any changes?

The stem and handlebar offer stiffness to match the frame, and there's no real sign of flex from the wheels either.

Which components had the most effect (good or bad) on the bike's efficiency? would you recommend any changes?

The wheels are a bit weighty, so if you can upgrade to something lighter you'll really unlock the performance of the Émonda.

The drivetrain

Tell us some more about the drivetrain. Anything you particularly did or didn't like? Any components which didn't work well together?

Performance-wise, 105 is probably all the groupset most of us will ever need from Shimano's catalogue. The shifting is great, as is braking power and modulation, and the value is good.

Tell us some more about the wheels.Did they work well in the conditions you encountered? Would you change the wheels? If so what for?

The Bontrager wheels are decent enough. They blunt the SL 5's climbing and acceleration a touch due to their weight, but I can't fault their durability.

Tell us some more about the tyres. Did they work well in the conditions you encountered? Would you change the tyres? If so what for?

Bontrager tyres typically offer decent performance, and so it is with the R1s. Like the wheels though they are a touch heavy and not the most supple.

Tell us some more about the controls. Any particularly good or bad components? How would the controls work for larger or smaller riders?

Good quality in-house kit. Upgrade if you want some bling, but there's no real need.

Your summary

Did you enjoy riding the bike? Yes

Would you consider buying the bike? Yes

Would you recommend the bike to a friend? Yes

How does the price compare to that of similar bikes in the market, including ones recently tested on road.cc?

This is well priced against a similar model in Specialized's Tarmac line-up, as mentioned in the review. There is tough opposition from the likes of Giant and Canyon, though.

Use this box to explain your overall score

The Émonda SL 5 is a very likeable bike; it has a solid dependable feel while still maintaining plenty of fun factor. There is some tough opposition out there price-wise, but would I feel shortchanged by the Trek? No. It has a quality ride feel and a quality build, and I enjoyed every mile I covered on it.

Trek Emonda Road Bike Review  

  December 21, 2017

By   Max Shumpert

Reviewed by Jeroen De Haas

The Trek Emonda is a high-speed, high-performance road bike that’s good on climbs, corners, and speedy descents.

The bike offers superior handling thanks to its Control Freak cable management system and innovative braking systems.

Most Emonda models use either high-performance Bontrager Speed Stop brakes or even more powerful Shimano flat mount disc brakes. A carbon fiber frame made of either Ultralight 500 or 700 Series OCLV Carbon makes the Emonda the world’s lightest production road bike, with the Emonda SLR 9 weighing just 640 grams.

That’s not to say that the frame is weak, however. Trek’s OCLV Carbon offers the ideal balance of weight, strength, and rigidity to keep cyclists comfortable throughout the duration of their ride. The Emonda can fit a wide range of riders. The seat can hold up to 275 pounds, while the frame can comfortably fit anyone between 4’11.8” to 6’5.2”.

The Trek Emonda comes in a wide variety of shapes and sizes that cater to both men and women alike.

There are a dozen different Emonda models that riders can choose from which differ in terms of size and complexity:

• Trek Emonda SL 5 : Trek’s lightest road bike, the Emonda SL5 offers the bare basics that every cyclist needs, including a 500 Series OCLV Carbon frame, Bontrager R1 Hard-Case Lite tires, and a Shimano 105 11 speed shifter.
• Trek Emonda SL 5 Women’s : This model is similar to the original SL5 but includes a saddle and touch points specifically designed for women.
• Trek Emonda SL 6 : Get incredible performance without the price tag with the Emonda SL6 series. The bike comes with a Shimano Ultegra 11 speed drivetrain, Bontrager Speed Stop direct mount brakes and Paradigm Tubeless Ready wheels.
• Trek Emonda SL 6 Disc : This model takes all of the top features of the Emonda road bike and adds hydraulic disc brakes to provide powerful, all-weather stopping power.
• Trek Emonda SL 6 Pro : The SL 6 Pro comes race-ready, including a streamlined carbon fiber frame, powerful Bontrager Speed Stop direct mount brakes, and durable Aeolus Pro 3 carbon wheels.
• Emonda SLR 6 : The SLR 6 uses better quality carbon fiber than SL 6 and SL 5 models. A 700 Series OCLV Carbon frame and a Bontrager XXX OCLV carbon handlebar make this bike durable while still only weighing around 640 grams.
• Trek Emonda SLR 6 Disc : Riders can enjoy all of the features of the SLR 6 along with the all-weather stopping power of hydraulic disc brakes.
• Trek Emonda SL 7 : An ultralight 500 Series OCLV Carbon frame, a Shimano Di2 electronic drivetrain, and carbon Aeolus Pro 3 wheels all make this high-end road bike both fast and robust.
• Trek Emonda SL 7 Disc : The SL 7 Disc offers dependable electronic shifting and hydraulic disc brakes for improved control.
• Trek Emonda SLR 8 : This bike model pairs a lightweight frame with a top-of-the-line Shimano Dura-Ace groupset and carbon Aeolus Pro 3 carbon wheels, allowing riders to reach top speeds effortlessly.
• Trek Emonda SLR 8 Disc : The SLR 8 Disc offers more stopping power than the SLR 8 by including flat mount hydraulic disc brakes.
• Emonda SLR 9 : The most advanced bike in the Emonda line, this model includes all top-of-the-line features such as a 700 Series OCLV Carbon frame, Aeolus 3 D3 carbon wheels, and a full Shimano Dura-Ace Di2 electronic drivetrain
• 2021 Trek Emonda SLR 9 : The New 2021 Trek Emonda SLR 9 has undergone an aero makeover with larger tire clearance. The Emonda frameset is still light and also has a threaded bottom bracket.

FRAME SIZE : Ultralight 500 or 700 Series OCLV Carbon. BRAKE TYPE : Shimano 105, direct mount, Bontrager Speed Stop, Bontrager Speed Stop Pro, Shimano Ultegra flat mount hydraulic disc. SHIFTER : Shimano 105 11 speed, Shimano Ultegra 11 speed, Shimano Dura-Ace 11 speed, Shimano Ultegra Di2 11 speed, or Shimano Dura-Ace Di2 11 speed. RIMS : Bontrager Tubeless Ready, Bontrager Paradigm Tubeless Ready, Bontrager Aeolus Pro 3, or Bontrager Aeolus 3 D3 Tubeless Ready TIRES : Bontrager R1, R2 or R3 Hard-Case Lite

Features We Like

The Trek Emonda offers a wide range of styles and prices, with the Emonda SL 5 going for around $2000.

We like that you can find a bike to suit just about any budget. It’s also nice that there are so many designs from which you can choose, from the bare-bones SL 5 to the top-of-the-line SLR 9. No matter what your road cycling needs might be, the Emonda is bound to meet them. We also appreciate the dependability of the Trek Emonda.

Year after year, it can withstand heavy wear and tear without you seeing any issues with performance. A strong 500 or 700 Series OCLV carbon fiber frame ensures that your bike remains in pristine condition throughout its lifetime. In addition to its strength, the Emonda’s frame is also well balanced and easy to maneuver. We like how easy it makes both uphill climbing and speedy descents. Carbon fiber is an ideal upgrade from aluminum for a racing bike, as it offers superior handling without adding weight.

• Easy to handle

Features We Don’t Like

Considering its lightweight design, it doesn’t come as much of a surprise that the Trek Emonda isn’t well-suited towards heavier riders. The frame can only support up to 275 pounds in weight, including any packs or cargo that you want to take along with you for the ride. The Emonda is also relatively limited in the height of riders it's able to accommodate. Individuals shorter than 4'11" or taller than 6'5" may not be able to reach the pedals and handlebars easily, making cycling unsafe.  

• Can only hold up to 275 pounds
• Fits a limited range of riders

Buying Advice for Consumers

This bike offers the bare bones of a high-end racing bike to reduce weight and drag. If you are looking for a fitness bike then Trek fx1 hybrid bike is the best bike you can get.

While this brings you a faster bike, advanced cyclists may be disappointed by the lack of bells and whistles accompanying the design. This bike is best for the racing or road cycling enthusiast.

It comes in models for both men and women, and you can find a variety of price ranges to fit your budget.

In Conclusion

The Trek Emonda is the world’s lightest racing bike, boasting a carbon fiber frame that’s both robust and incredibly lightweight.

2017 Edition — Trek Émonda S 5 Road Bike: Review

The Trek Émonda S 5 Road Bike

With 300 Series OCLV Carbon, the Emonda S 5 offers riders the best-in-class weight, stiffness, and strength.

With an H2 fit, this optimal fit is a near-perfect fit for most riders, including Pro Team athletes. The H2 fit gets riders in the correct position for performance and power.

Blendr Stem

The Trek Émonda S 5 features the Bontrager Blendr Stem by Trek. This is a highly integrated system for easy and clean stem installation of computers, lights,and other biking accessories. You simply begin with a Blendr Stem and add the appropriate base and finish with a mount that matches your accessories.

The Trek Émonda S 5 is built with an Ultralight 300 Series OCLV Carbon frame. The frame design down to the component parts were designed to serve a goal — to be one of the lightest performance bikes offered. The ride-tuned balance and handling elevates this Trek Émonda to another level.

OCLV is short for Optimum Compaction, Low Void, which refers to the carbon manufacturing process that Trek engineers developed decades ago. This allows them to produce carbon framed bikes with consistent, high quality that was not possible before.

The 300 Series OCLV Carbon offers best-in-class weight, best-in-class carbon, and gives the rider stiffness and strength. The 300 Series is at the lower end of the carbon scale, but it keeps the price down, areal weight low, and quality of the frame excellent for a nice price.

The 300 Series OCLV is a great choice for this bike’s frame, as it is compliments the stiffness and weight ratio well. With the right relationship of stiffness-to-weight, the performance of the road bike increases. Trek tested every part of the frame extensively to maximize handling and pedaling performance, as well as ride feel of this S 5.

Trek bikes range: which model is right for you?

• Sign up to our newsletter Newsletter

The humble beginning of Trek bicycles took place in the "red barn" - once a carpet warehouse - in Waterloo, USA. The first bikes were steel touring frames , but within three years the brand had expanded substantially.

Eventually outgrowing the barn, Trek moved into a much larger headquarters - still in Waterloo - in the year 1980. From there it began to manufacture road racing bikes, then in 1983 created its first mountain bike before moving into accessories come 1984.

Having started out in steel, Trek moved into developing aluminium bikes in 1985. The first Trek branded full carbon frame came in 1989 - the Trek 5000 had a frame weight of 1.5kg. It was built by an outside manufacturer and discontinued after a year. Trek made its own efforts at carbon, with an in-house production, in 1992 to much greater success.

>>> Trek mountain bikes: which model is right for you?

Now, Trek offers the Madone (aero bike), Domane (endurance bike), Emonda (lightweight race bike) and Checkpoint (gravel bike) as well as the Boone cyclocross and Speed Concept time trial machine.

Trek's OCLV Carbon

You can trust Cycling Weekly. Our team of experts put in hard miles testing cycling tech and will always share honest, unbiased advice to help you choose. Find out more about how we test.

Trek's carbon bikes have always used their own patented 'OCLV carbon' - this stands for Optimum Compaction Low Void. It believes this carbon creates the best compromise between low weight and high strength and stiffness.

Optimum Compaction refers to the way sheets of carbon are layered into the mould, and optimised via heat and pressure - in Trek's opinion the two treatments are administered to the perfect ratio. Low Void refers to the minimisation of space between the layers of carbon, which might otherwise reduce strength and durability.

In 1995, Trek opened an independent facility inWhitewater, Wisconsin. The idea being that the Waterloo factory would work in frame development only. For those who want to customise their ride, the'Project One' custom paint programme arrived in 2001.

Trek's pro cycling support

Trek supported now disgraced American cyclist, Lance Armstrong, through his peak years. In 1997, it helped him sign with their sponsored team, US Postal Service Pro Cycling. He won his seven editions of the Tour de Frances on bikes bearing the brand name, but all of said wins were later taken from him following doping violations.

In 2014, the brand sponsored the Trek Factory Racing Team, now calledTrek–Segafredo. In that role, it provided bikes for high profile winners such as Fabian Cancellara and Alberto Contador,as well as Jens Voigt, and notably his Hour Record in September 2014.

In 2020, Trek continued to support the Trek-Segafredo men's and women's race outfits, two highly successful teams.

Trek's acquisitions

Over the years, Trek has made a number of high profile acquisitions. The most famous, perhaps, Gary Fisher bicycles - the mountain bike brand which it took over in 1993.

Later came Bontrager Cycles in 1995 and Electra Bicycle Company in 2014. Bontrager, now Trek's component and apparel brand, maintains the same name as does Electra, the creator of leisure bikes and accessories.

Trek's road bike models

Trek is able to offer a wide range of different bikes, each tuned to a slightly different purpose. Some model families are available in a selection of standards (SLR premium carbon, SL carbon, ALR premium aluminium and AL aluminium), and then these come with assorted levels of componentry to suit your price bracket.

To add even more depth to the range, Trek offers many models in two different 'fits'. The Madone and Émonda come as standard in an H2 (traditional) fit, but there are versions in what it calls 'H1' fit. This is more aggressive, shaving off about 30mm on the head tube to create a longer, lower ride. The Domane comes in an H2 'Endurance' fit, with a few models in 'Pro Endurance', again with a longer and lower stance on offer.

Here's a look at the key model families...

Trek Domane

Our expert review:

Reasons to buy

Reasons to avoid.

The Trek Domane was introduced in 2012. It was created to offer a comfortable ride, the key feature being an IsoSpeed decoupler which separated the seat tube from the top tube, thus reducing vibrations and fatigue.

In 2016 it gained theFront IsoSpeed, which helps to reduce vibrations at the front end without impacting handling. This came alongside a new slider, which alters the level of dampening offered by the rear.

In its most recent update , the Domane took notes from the Madone with an aero fork profile, whilst becoming more versatile thanks to clearance for 38mm tyres (without mudguards, 35mm with). It also gained a downtube compartment for stashing tools (or snacks!).

Though comfort is important to the Trek Domane, it's still a racing frame, and its prowess has been demonstrated by UCI WorldTour riders at major one-day Classics, such as Strade Bianche and the Tour of Flanders. The top Domane bikes come with an H1.5 fit, which was developed with the Trek-Segafredo teams to offer the optimal balance between aerodynamics and endurance.

The Trek Domane - available as a men's build or with women's specific componentry - is a fast selling model, which comes in a range of frame materials.

The Domane SLR uses the lightest carbon Trek offers, the SL is one step down, whilst the AL uses aluminium and is the cheapest of the range.

Trek Madone

The Trek Madone is quite another beast, and the bikes come built for men and women; the latter's models with women's saddles and narrower handlebars . With an aggressive geometry and stiffness to boot, it's a road race hero, and aerodynamics have become part of its lifeblood. When we tested five aero bikes , head to head, the Trek Madone came out fastest.

Modern Trek Madone's feature a high level of integration, with the cables tucked away yet reachable via an access point at the top of the down tube.Wind tunnel testing has helped Trek to create theirKVF (Kammtail Virtual Foil) tube shapes, used on the frame and fork. These unconventional tube shapes are designed to further reduce drag, helping the rider/bike unit to slice through the air efficiently.

Because being bumped around doesn't make you faster, the Madone also features an IsoSpeed decoupler at the seat tube and more recently an adjustable one at the head tube, which offers greater compliance whilst still being integrated to prevent adding drag.

The newest model, according to Trek, can offer 17 per cent more compliance through to 21 per cent more stiffness, depending upon your chosen setting. A damper at the seatpost is also said to cut rebound by 13 per cent. All of these stats add up to a bike that can be comfortable and stiff at the same time - and one that earned a place in our 2018 Editor's Choice awards.

The majority of the bikes come in a more relaxed 'H2' geometry, save for the Madone SLR, which is in an 'H1.5' fit - this is designed to allow riders to achieve an H1 fit or an H2, depending upon their set up.

Trek Émonda

Adding more depth to the Trek family is the Trek Émonda, launched in 2014. Designed to be a climbing bike, newer adaptations are capable of negotiating mixed terrains - with disc brakes available and tyre clearance to 28mm.

>>> Trek Émonda range explained

Trek continues to work on developing the Émonda, dropping the weight of the top end Trek Émonda SLR to 640g in a size 56cm (665g with discs) and 1091g for the Trek Émonda SL (1149g with discs). The weight difference is largely achieved by the use of700 Series OCLV carbon on the SLR, as opposed to 500 series on the SL.

The aluminium model has seen some major work and the result earned it a place in the Editor's Choice 2019 awards. The key characteristic we loved was the way it simply didn't look, or ride, like aluminium. A lot of this is down to Trek's 'Invisible Weld Technology' which increases the surface area of the frame, adding to strength and reducing weight. The ALR model's frame weight comes in at a competitive 1112g, or 1131g with discs, and it uses the brand's 300 Series Alpha Aluminium.

The carbon models are available in 'SLR' build or 'SL', the former being the lightest and the latter more affordable. The majority of Trek Émonda bikes cone in an 'H2' fit, but they can be purchased in an 'H1' geometry, if you choose the top end 'Race Shop' version.

There are a few nods to neatness and integration around, such as the use of 'Blendr Integration' which seamlessly mounts Bontrager’s cycling computer, Ionbike lights or even Garmin computers directly to the handlebars. On SLR versions there's ‘Control Freak Cable Management’ which allows for shifter and brake cables to be housed through the frame.

Trek Checkpoint

With gravel and adventure bikes a fast growing category, the Checkpoint is Trek's offering to fill that sector. The crucial element here is that both the SL and ALR frame options come fitted out with 35c gravel tyres, and can accommodate rubber up to 45c. They've all got internal cable routing, to ensure much stays out, whilst the higher end models use 'Control Freak' routing which is neater.

>>> Best gravel bikes: the top models reviewed

If you opt for the carbon SL model, you get vibration dampening from an IsoSpeed decoupler at the rear, too.  To provide stability and confidence on light trails as well as comfort on all-day adventures, the geometry is not as aggressive as the road bikes elsewhere in the range. Such all-day rides warrant plenty of kit, so there's mounts for racks and mounts. Similar to elsewhere in the range, there's AL, ALR and SL models.

Trek Speed Concept

Trek's Speed Concept time trial bike has been raced by the pros yet is still seen on the amateur race scene as a popular option.

>>> Check out Fabian Cancellara's 2016 Speed Concept

The frames use 500 Series OCLV Carbon, boasting the KVF (Kammtail Virtual Foil) tube shapes described in the Madone, plus a carbon fork with integrated brake and stem - the key goal being cutting through the air quickly.There's space to fit Trek's SC Draft Box and SC Sped Box, largely used by triathletes carrying snacks.

Trek Boone 5

Trek's got plenty of experience in the muddy realm of off-road cycling - and they've got a selection of cyclocross bikes. The Trek Boone 7 model comes with hydraulic disc brakes, a one-by crank and 12-speed cassette and they've all got Bontrager's own 33c cyclocross tyres.

The frame material is Trek's 600 series OCLV carbon, and there's front and rear IsoSpeed decouplers to help riders negotiate the mud without excess transfer of vibration. Combining the mud ready tyres, disc brakes, 'cross focused cable routing and geo into an aluminium package is the Trek Crockett family.

They key differentiation is the frame material, which is300 Series Alpha Aluminium, and there's no decoupler. However, it's still a performance bike that's ready to race.

"One of the fiercest climbing bikes available, the new Émonda is even faster thanks to a dose of aero"

"I expect so much from a modern high-end pro-level road racing bike that it’s hard to exceed those expectations. It’s rare when a bike does: The Émonda SLR is one of those rare bikes."

"It's an incredible update from Trek"

"The updated Emonda packs one helluva punch, and Trek has a winner on its hands. The integrated cockpit is nice and all, but the real win is the H1.5 fit, which makes the Emonda feel more stable while maintaining the aggression and responsiveness of previous Emondas. That, coupled with a lightweight construction, comfortable ride, and aerodynamic shaping, brings Trek's top of the line climber from a very good bike to an excellent one."

"The Emonda is still light, and it’s still stiff, but now there’s an extra dose of free speed"

"Overall, Trek has done a solid job here of updating the Emonda, infusing meaningful improvements in several key areas, but without breaking the basic formula that has made the bike so popular."

Trek lays up OCLV 500 carbon fiber to lower the entry point on new Madone SL

• Click to share on Facebook (Opens in new window)

Love the Trek Madone SLR but can’t stomach the price tag? Now there’s hope with the new Madone SL. Built from the very same molds as the SLR, the SL model includes the use of a slightly heavier grade of carbon fiber which adds some weight, but helps lower the price – making Madone tech accessible to more riders than ever.

The Madone SLR frame is a thing of beauty, and the SL is no different. After all, they literally come from the same molds. However, Trek builds the SL with OLCV 500 carbon fiber instead of the OCLV 700 found on the SLR. This is said to add about 100g to the weight of the frame, with a 56cm painted Madone SL frame said to weigh 1225g.

Because the frame is the same, you’ll find Trek-specific features like their Adjustable Top Tube IsoSpeed unit which allows you to fine tune the rear end compliance by moving the integrated slider. It also uses the same proprietary seat mast assembly as the SLR.

Up front, the SL uses the same fork as the SLR, but one huge difference is the use of a standard bar and stem rather than the integrated unit found on the SLR. This is done in part to keep the cost down, but it also makes it easier to better fit more riders, and also allows for the use of clamp on aero bars.

Like the SLR, you’ll find integrated lighting and computer mounts through the use of the Bontrager Blendr system.

Elsewhere, the frame uses the same specifications as the SLR with flat mount disc brakes, 12mm thru axles front and rear, internal cable routing, Duo Trap S compatibility, BB90 bottom bracket, and clearance for 28mm tires. Calling it their H1.5 fit, the bike is built with a performance geometry and KVF aero tube profile to be every bit as racy as the higher end versions.

Two different builds will be offered with the SL 7 running Shimano Ultegra Di2 with Bontrager Aeolus Pro 5 carbon wheels, and the SL 6 which runs Shimano Ultegra mechanical with hydraulic brakes and Bontrager Aeolus Comp 5 carbon wheels. While the Madone SL 7 is close to the price of the Madone SLR 6, you’ll find the SL gets you a Di2 drivetrain, while the lighter SLR frame is equipped with mechanical. There’s also a frameset available if you want to build it yourself.

All models are in stock and available now.

• Madone SL 6 Disc $4,699.99
• Madone SL 7 Disc $6,499.99
• Madone SL Disc F/S $3,499.99

I will never buy a Trek with a BB90 bottom bracket.

Rumors of T47 BB standard coming to Trek OCLV carbon can’t come true fast enough?

Needs BSA. At least Specialized is going back to basics with their new Roubaix line.

YMMV, but I’ve got a Trek with BB90 and have never had a moment’s problem with it in 4 years.

4 years isn’t very long and it’s really mileage and your power that matters for causing the inevitable unless you have a one piece BB like a BBinfinite setup

Looks a bit weird with that seatpost with half a mile of setback.

Really? I’m considering selling a kidney to buy one! 😛

Would agree friend of mine has an RSL edition with rim brakes and I was just thinking how much better his frame looks than the disc brake one.

It’s not a bike it’s a ugly Trek billboard! The designers are tasked with fitting the biggest trek logo on it while allowing the thing to be semi rideable.

You’re right… what’s up with the size of the TREK logo? I used to think the Madone was so sleek and beautiful, but somehow it’s gotten really ugly.

Yeah, the black on black “ghost” logo is textbook complimentary color strategy for maximum contrast…

Veru odd looking bike especially that seat/setback but I’m really liking the integration with lights.

I do wonder if that bike will say “Made in USA” on it (like so many other Treks that were at best assembled in the USA). At least the big S was honest-ish with “Designed in California” (that to me is a reason to not buy one).

I do prefer made in USA frames (with made in Italy bits)…that said, I do prefer to meet the person who builds my frame in person as well.

I think Trek already moved all production back to Asia.

Trek never did that. They’re all made in Asia(even when this post was made), but they used to make their 6 series and up frames in the US while the 4/5s were made in Asia. The frames stated where they were made.

I’ll take my Fuji Transonic 2.1 over that bike anyway. It’s a rocket ship and is $1K less than the Ui2 version Trek is offering. And they didn’t dummy down the carbon to hit a price point.

Nothing about this bike or the SLR appeals to me in the slightest.

Title : Active carbons as nanoporous materials for solving of environmental problems

However, up to now, the main carriers of catalytic additives have been mineral sorbents: silica gels, alumogels. This is obviously due to the fact that they consist of pure homogeneous components SiO2 and Al2O3, respectively. It is generally known that impurities, especially the ash elements, are catalytic poisons that reduce the effectiveness of the catalyst. Therefore, carbon sorbents with 5-15% by weight of ash elements in their composition are not used in the above mentioned technologies. However, in such an important field as a gas-mask technique, carbon sorbents (active carbons) are carriers of catalytic additives, providing effective protection of a person against any types of potent poisonous substances (PPS). In ESPE “JSC "Neorganika" there has been developed the technology of unique ashless spherical carbon carrier-catalysts by the method of liquid forming of furfural copolymers with subsequent gas-vapor activation, brand PAC. Active carbons PAC have 100% qualitative characteristics of the three main properties of carbon sorbents: strength - 100%, the proportion of sorbing pores in the pore space – 100%, purity - 100% (ash content is close to zero). A particularly outstanding feature of active PAC carbons is their uniquely high mechanical compressive strength of 740 ± 40 MPa, which is 3-7 times larger than that of  such materials as granite, quartzite, electric coal, and is comparable to the value for cast iron - 400-1000 MPa. This allows the PAC to operate under severe conditions in moving and fluidized beds.  Obviously, it is time to actively develop catalysts based on PAC sorbents for oil refining, petrochemicals, gas processing and various technologies of organic synthesis.

Victor M. Mukhin was born in 1946 in the town of Orsk, Russia. In 1970 he graduated the Technological Institute in Leningrad. Victor M. Mukhin was directed to work to the scientific-industrial organization "Neorganika" (Elektrostal, Moscow region) where he is working during 47 years, at present as the head of the laboratory of carbon sorbents.     Victor M.

2024 Scott Addict RC vs Trek Emonda

In this article, our bicycle authority Alex Lee compares the Scott Addict RC and Trek Emonda, comparing the variant, features, technologies and pricing.

In this article, I’ll guide you through a comparison between the Scott Addict RC and Trek Emonda ; both popular road bikes among cyclists.

I’ll walk through the Scott Addict RC and Trek Emonda models lineup, their specifications, and retail pricing (USD). I’ll explain the carbon fiber technology used ( Scott High Modulus Carbon vs Trek OCLV ), and unique frameset features for each bike.

The goal is to help you get a better understanding before you make your final purchasing decision.

Scott Addict RC

The Scott Addict RC Ultimate is a top-of-the-line model made from the superlight HMX SL Carbon . The Scott Addict RC Pro is next in line with the HMX Carbon. Both models have a fully integrated, one-piece carbon handlebar.

Further down the line are five Scott Addict RC models built with the HMX Carbon . They use a two-piece aluminum handlebar, and the cables are fully hidden. RC stands for Racing Concept , and the Addict RC is Scott’s performance racing bike.

There’s also a women-specific Scott Contessa Addict RC similar to the standard version, except for the touchpoints, saddles, handlebars , and compact cranksets .

Scott vs Trek carbon fiber

Scott high modulus carbon.

Scott implements two primary types of carbon fiber technology in their bicycle frame construction; HMX-SL , HMX , and HMF carbon.

• HMX-SL ( High Modulus Xtreme, Super Light ) carbon is the pinnacle of Scott’s carbon fiber technology. This innovative blend of carbon fiber is designed for ultimate stiffness and minimal weight. Scott uses HMX-SL Carbon in their highest-end models, such as the premium version of the Scott Addict RC Ultimate and Foil RC Ultimate road bike. These bikes, with HMX-SL Carbon frames, are the go-to choice for professional cyclists competing in world-class races.
• HMX carbon is a level below the HMX-SL, and is still a top-tier carbon material offering a fantastic blend of stiffness and lightweight construction, albeit not as light or rigid as the HMX-SL. It’s an excellent choice for serious and experienced cyclists looking for a high-performance bike without the additional premium.
• HMF ( High Modulus Fiber ) carbon, may not be as light or stiff as HMX carbon, but it’s still a superior material that contributes to a robust, light, and efficient ride. Scott uses HMF carbon in their bikes that strike a balance between affordability and performance.

Trek OCLV carbon

The OCLV (Optimum Compaction, Low Void) carbon is a proprietary carbon fiber manufacturing technology developed by Trek.

• Optimum Compaction refers to the heat and pressure applied during the curing process to squeeze out excess resin and ensure that the carbon layers are compacted to the optimal density.
• Low Void refers to the goal of reducing microscopic air pockets or voids that can occur in the carbon fiber and create weaknesses.

One of the key advantages of OCLV carbon is its ability to achieve an optimal balance between stiffness, strength, and weight. Trek engineers carefully tune the carbon layup and utilize varying modulus carbon fibers to create stiff frames in certain areas to maximize power transfer while maintaining compliance in other areas to enhance comfort and ride quality.

The OCLV carbon is available in 800 and 500 series.

• OCLV 800 is the highest-grade carbon fiber used by Trek. The carbon modulus is higher in OCLV 800, making it stiffer and lighter. The manufacturing process is more refined, using more advanced carbon and resins, leading to a bike frame that provides top performance levels for stiffness, weight, and strength. OCLV 800 is used in all models with SLR .
• OCLV 500 is a lower-grade carbon but still offers a high level of performance. It has a slightly lower carbon modulus, meaning it’s a bit less stiff and heavier than OCLV 800. OCLV 800 is used in all models with SL .

It’s worth noting that the different OCLV grades don’t only refer to the material itself, but also to the manufacturing techniques used to form the carbon fiber into bike frames. Higher-grade carbon requires more precise manufacturing techniques to take full advantage of its superior material properties.
