Trek X-Caliber 7 review

Trail-ripping budget 29er

David Rome/Future Publishing

The name X-Caliber isn't new to Trek, but for 2014, it will refer to an entire range of entry level 29er hardtails. The frame of this new X-Caliber range has been entirely redesigned, borrowing much design inspiration from Trek’s World Cup winning Superfly line-up.

Note: We have now reviewed the 2015 Trek X-Caliber 8 .

Ride and Handling: elite handling and confidence for beginners

When it comes to 29in wheels, Trek and their Gary Fisher collection have been doing them the longest. The X-Caliber has their dialled and respected geometry, including Trek’s proprietary G2, which changes the fork offset and aims to create a livelier ride.

We found the X-Caliber nimble and playful on the trail. The combination of a roomy top tube and short 75mm stem made it easy to loft the front wheel and get airborne. With our position centrally between the wheels, long climbs were comfortable, and maintaining power felt natural.

The quick, joyful handling and perfectly balanced geometry went a long way to hiding the overall high weight. It lacked urgency on steep climbs and stop-and-start riding, but once we got the X-Caliber going, the ride was brilliant, helped by the big wheels' fast-rolling tyres .

The SR Suntour XCR fork featured well-sized 32mm stanchions and helped the X-Caliber hold its line though corners and rock gardens. The suspension was basic but effective. A fixed rebound setting offered a balanced feel without harsh spiking or excessive packing down between hits. We found the spring on a medium test bike was ideal for a 70 to 85kg rider, offering respectable control over both small and large bumps.

The fork’s lockout can be activated while on the bike and would hold the position it was locked at. So if you wanted a lower front-end for road riding, you can push down on the fork, lock it, and you’ll achieve a lower position.

Short head tube and plenty of steerer tube length

The short head tube and long steerer tube provided plenty of handlebar height adjustment and we easily found a comfortable height with room to spare, which is not the case with many other entry-level 29ers.

Frame and Equipment: money spent on areas that matter most

The X-Caliber frame is no doubt the highlight of the package, made with Trek’s Alpha Gold aluminium. With heavily shaped and butted tubes, sparkling paint, an internally guided front derailleur cable and a fully housed rear derailleur cable, this frame would be befitting of bikes twice its price.

Rear pannier mounts add extra versatility

It has great off-road potential, and more versatility boxes are ticked with solid rear rack mounts. A change to 700c road tyres would make it a fast commuter for mid-week use too.

There's no chainstay or seatstay bridge at the rear of the frame, so tyre clearance is generous with little place for mud to hang onto. Sadly, the cheap front derailleur undid these clearance benefits, and if you want to fit a wider rear tyre you will need a slim-profile front derailleur.

Basic Shimano gears – the front derailleur didn't leave much tyre clearance

Given the entry-level price of the X-Caliber 7, something had to give – and in this case it was the drivetrain, and what a smart decision that was. The industry norm is to spec a high quality drivetrain, save money elsewhere and let the customer make their purchase decision based on the level of Shimano equipment. But the truth is that the Shimano parts are the cheapest to replace and the most likely to get damaged, so instead Trek have invested in longer lasting, more crucial components, such as the brakes and fork.

The 27-speed drivetrain provided plenty range and the mix of Shimano Acera and Altus performed better than expected, although the soft rear derailleur caused excessive chain slap. The Acera shifter offered a better feel than commonly used cheaper shifters. The basic Shimano chainset is hefty and the plastic leg guard won’t last many missed log hops, but replaceable chainrings were a bonus.

The XR1 tyres were fast and grippy

The Bontrager XR1 tyres were fast rolling, full of traction in dry conditions and well-suited to the versatile X-Caliber. Tyres sizes are mixed, with a wider front tyre for traction and a slimmer rear for weight. Trek's componentry choices show real off-road knowledge.

Much of the finishing kit is from Trek’s house brand, Bontrager , a well-respected component brand in their own right. The basic Bontrager parts offered a few highlights, such as the comfortable Evoke saddle, the secure and slim twin-bolt seatpost, and the super wide, perfectly swept handlebars. Even the wheels (with their bling red hubs) felt stiff and capable enough for serious off-road use – they were only let-down in the weight department.

The Shimano M395 hydraulic brakes offered consistent braking performance and low noise, they are our favourite brake for the price point. Our only gripe is the continual use of a cheaper 'resin only' brake rotor, which prevents the use of a more durable sintered brake pad. An adjustable reach lever blade is another bonus, something omitted from often-seen basic Tektro units.

The included pedals are basic plastic numbers, best suited for car park tests. Be sure to factor in the additional expense of a pair of metal platform or clipless pedals, because you'll want them.

The X-Calibre is a true class act, with an amazingly well executed frame with exceptional geometry, well behaved fork and quality finishing kit. Ride the guts out of it and upgrade the derailleurs once they break or wear – the X-Calibre is a top pick.

‍ There’s a lot to consider when shopping for a hardtail. In this Trek X-Caliber 7 review, I dig into the details to help you choose if this is the bike for you.

The Trek X-Caliber 7 is a fantastic entry-level bike for someone wanting to get into racing or long cross country singletrack rides. For only $1,099, this bike gives you a full range of modern features including an advanced aluminum frame, hydraulic disc brakes, and a wide-range 1x10 drivetrain.

While I’m no racer, I love going fast and far on capable cross-country bikes. I’ve ridden most of the best entry-level XC bikes, and for this review I dug into the specs and performance of the Trek X-Caliber 7 to see how it measures up to some of my favorite hardtail speed machines.

TABLE OF CONTENTS

‍ Trek X-Caliber 7 Performance

This is definitely a cross country machine that emphasizes speed and light weight over aggressive downhill riding. The X-Caliber 7 feels awesomely light and nimble and is easy to steer around obstacles.

With a lower-than average reach and a steep 69.5-degree head tube angle, this bike is definitely designed more for efficiency than charging down technical descents. This bike feels fun and fast on moderate flowy singletrack, but as trails get steeper, the forward riding position will start to be pretty sketchy.

The 100mm Solo air spring fork works great for smoothing out trail vibration, but it definitely isn’t enough for really rocky, rough hills. If you want a hardore hardtail for ripping down technical descents, this is definitely not the bike for you.

The X-Caliber 7 really excels while climbing. The stiff aluminum frame does a great job of sending all your power straight to the rear wheel. At 29.5 lbs, this bike definitely won’t feel like it’s weighing you down.

If you like crushing up long climbs, you’ll feel right at home on the X-Caliber 7.

The main shortcoming of this build is in the drivetrain gear range. The 10-speed Shimano drivetrain is a common one on bikes in this price range, but the rear derailleur is limited to a11-46 cassette. This is a descent range, but it may leave you wanting a lower gear on really steep climbs.

Trek X-Caliber 7 Frame and Geometry

The X-Caliber 7 is built around a lightweight and durable alloy frame. Trek is at the top of the game when it comes to aluminum frame manufacturing, and it really shows in this bike. This frame feels exceptionally light and responsive on the trail.

The frame has decent tire clearance for cross country tires, though you won’t be able to fit big 2.6” knobby tires on here.

The tapered head tube and internal dropper post routing make this frame future-proofed and upgrade-ready.

Specs and Components

For just $1,099, the Trek X-Caliber 7 comes with a solid and capable build kit. There are a few compromises that Trek made to hit the price point. Here is a breakdown of the key components and what to expect in terms of performance.

The Trek X-Caliber 7 comes with a Shimano Deore 10-speed drivetrain. This drivetrain is used on a lot of bikes around this price range, and it offers very reliable shifting performance with a sturdy rear derailleur that will hold up to abuse.

The downside with this drivetrain is that it has a limited 11-46 cassette size. Top end drivetrains typically have 11-51 or even 10-51 cassette range. With a 46-tooth big gear, you have a limit to low-end gears for climbing.

If you get this bike, the drivetrain may be the first thing you want to upgrade.

The X-Caliber 7 is fitted with the RockShox Judy SL Solo Air Spring Fork. This fork only has 100mm of travel, so it won’t soak up big hits, but it is smooth and responsive and works great for smoothing out the smaller vibrations of cross country trails and keeping your front tire in contact with the ground.

This fork is great for fast cross country riding, but will bottom out on rockier trails.

The Shimano MT200 hydraulic disc brakes included on the Trek X-Caliber 7 aren’t the most high-performance brakes available, but they are great for this price point.

With a 180mm front rotor and 160mm rear rotor, you’ll get plenty of braking power for cross country riding.

The X-Caliber 7 is fitted with Bontrager Kovee double-wall aluminum wheels with Formula hubs. These rims are tubeless-ready out of the box, which is great so you can upgrade to tubeless easily without needing to buy new wheels.

The rims are fairly lightweight for aluminum, and they’re durable and will last you a long time.

The Bontrager XR2 Comp MTB Tires that come on the X-Caliber 7 are heavily focused toward speed and low rolling resistance. They have very low-profile knobs and don’t have great cornering traction.

For cruising on easy singletrack, these tires are fast and won’t slow you down. If you ride on loose trails, you’ll probably find yourself wanting more grip.

Competition for the Trek X-Caliber 7

The market for mountain bikes around the $1,000 price range has tons of options to choose from. The X-Caliber 7 measures up pretty well with the competition and offers great value for what you pay. If you are looking for the lightest, raciest cross country hardtail in this pricepoint, the X-Caliber is a great choice.

Here are a few of the top competitors for the X-Caliber 7 and how they compare.

Trek X-Caliber 7 vs Cannondale Trail SE 4

The Cannondale Trail SE 4 is a direct competitor with the X-Caliber 7. At $1,175, it’s a tad more expensive, but it’s easy to find on sales.

The Trail SE 4 has a pretty similar design to the X-Caliber. They have the exact same Shimano 10-speed drivetrain, and a fork that has 20mm more suspension, but is coil sprung.

If you’re looking for a more capable all-around bike, the Trail SE 4 is probably a better choice. It has more aggressive geometry with a 66.5-degree head tube angle, and the frame has more advanced modern features like flex zones in the rear triangle to mute trail buzz. The Trail SE 4 also has thru-axles, which are a better design and more compatible with modern wheels if you want to upgrade.

The X-Caliber is almost two-pounds lighter, and is better for a race-focused cross country rider.

Trek X-Caliber 7 vs Specialized Rockhopper 29 Expert

The Specialized Rockhopper 29 Expert is one of the most popular entry-level hardtails on the market. It has the same Judy air fork as the X-Caliber, and there really isn’t much difference between the frames: they both have quick-release axles, .

The Sram SX Eagle 12-speed drivetrain on the Rockhopper offers better gear range than the 10-speed on the X-Caliber, though it may be a bit more difficult to get dialed in just right.

There really isn’t much differentiating these bikes other than the drivetrain. Your choice will probably depend on what is available at the bike shop and what color you like more.

Trek X-Caliber 7 vs Canyon Grand Canyon 5

The Grand Canyon 5 is a fantastic aluminum hardtail that comes at a shocking price because of Canyon Bicycle’s direct-to-consumer business model. At $899 plus $100 shipping, it’s still $100 less than buying the X-Caliber at a bike shop.

The Grand Canyon 5 has a lot going for it. It has more aggressive geometry, longer fork travel, and a significantly better Shimano 12-speed drivetrain.

If you are really focused on weight and pure speed, the X-Caliber makes sense, but for a more fun all-around bike at a lower price, it’s hard to argue against the Grand Canyon 5.

Where to Buy the Trek X-Caliber 7

For 2022-2023, Trek has phased out the X-Caliber 7 to leave room for other models, so you can’t purchase it directly from Trek. It may still be in stock at your local bike shop.

The bike that’s replacing the X-Caliber 7 in Trek’s entry-level cross country hardtail lineup is the Trek Marlin 7 Gen 2 . It is almost identical to the X-Caliber in terms of frame, geometry, and components. Here are a few places you can shop for the Marlin 7:

• Windsor Bikes and Sport

Trek X Caliber 7 Review: Is It A Good Bike To Buy?

• By Daniel Shakibaie
• Mountain Bike , Trek Bikes

Welcome to my Trek X Caliber 7 Review.

I have tested/bought a dozen mountain bike and I have come to the conclusion that if you want to get serious about mountain biking then  The Trek X Caliber 7 should be your pick. 

Trust me, you don’t want to buy the wrong bike. It’s better to get it right the first time, or you will waste over $1000 on not up to standered mountain bike.

The Trek X Caliber 7 is what many would consider an entry-level bike in terms of the price. At roughly 1k, it’s a reasonably priced machine designed to give you a lot of room to grow before you need a more advanced bike. 

The frame is reasonably lightweight, and everything about this bike is optimized to make upgrading the different components simple and affordable. 

Both of the color finishes available on the X Caliber 7 are beautiful. The paint is durable and hard-wearing, and the overall design looks good. 

While this might not be the most durable mountain bike out there, it’s more than up to the challenge of most XC trails. Lightweight enough to work well in most settings, the X Caliber 7 is also designed with cargo racks that make it a good option as a commuter, cross country, and leisure bike. 

Things to Consider Before Buying XC Bike 

Like most specialized bike designs, cross-country bikes are built with a particular purpose in mind. On average, these bikes have more significant suspension than your average commuter or leisure bike. They also often offer larger, much grippier tires, and a more aggressive seated position. 

These bikes are designed for rough, uneven terrain. They’re good in most weather conditions, and often feature a better braking system than commuter bikes. 

However, those adaptations all add cost to the bike. If you’re more likely to be riding on pavement most of the time, and will rarely, if ever, find yourself on a mountain bike trail, you’d probably be better off with a different style of bike. 

Always look to match the core features and benefits of your bike to it’s most common, or most technically challenging, use. 

Is the Trek X Caliber 8 a Better Bike Option Than the Trek X Caliber 7?

In the trek x caliber 8 bike review , it becomes evident that it offers some notable advantages over the Trek X Caliber 7. With upgraded components like the RockShox Judy Silver fork, hydraulic disc brakes, and a 1×12 drivetrain, the X Caliber 8 delivers improved performance and enhanced versatility. Additionally, its lightweight Alpha Gold Aluminum frame ensures an agile and responsive riding experience. For those seeking a superior bike option, the Trek X Caliber 8 proves to be a compelling choice.

Features & Benefits

The frame is always one of the single most important aspects of your bike. The weight and design of your bike frame can make a significant difference in its performance. Not to mention its impact on how hard you have to work to get the bike up and going. 

The X Caliber 7 is built with an Alpha Gold Aluminum frame. It’s relatively lightweight, but with plenty of added durability to handle rough rides.

It’s also got an internal routing system. Not only does that mean that your bike looks cleaner and more professional, but it also cuts down on the chance of early wear and tear on your cabling. You’re much less likely to wind up with cut brake lines or other component failures thanks to the internal routing. 

It’s also well balanced, giving you better overall control and a lot more maneuverability when riding.

Suspension System

The primary suspension system on this bike, like most XC bikes in this price range, is in the fork. The bike comes with a RockShox 30 Silver fork, that offers 100mm of travel. That’s enough to absorb shock on the road and from normal bumps and bruises on the trail. 

It also has a locking mechanism so you can depress the coil and eliminate the suspension anytime it isn’t needed. 

This fork also has 51mm offset on the largest size wheels, 29″, which gives tires a little more room to move and adapt to the demands of the trail. 

Trek’s smart sizing system helps to ensure that your bike will be fitted with the best possible wheels for the frame. There are two wheel sizes to choose from, and while most frame sizes will be fitted with the more aggressive and efficient 29″ wheels, smaller wheels are more effective for shorter riders on the smaller frame sizes. 

Whatever wheel size your frame comes with, 27.5″ or 29″, you’ll have plenty of traction. The wider rims allow you to mount tires with good grip and deep traction for wider terrain riding. 

The design isn’t quite tubeless-ready. But, upgrading to a tubeless-ready rim is simple enough, and shouldn’t be too expensive. 

Shimano makes the entire drivetrain on the x Caliber 7 . You’ll have a Shimano Acera M3000, 9 speed, and a Shimano Acera SL-M3010, 2 speed, giving you a total of 18 gears for maximum flexibility. 

Since you’ll also be working with Shimano derailleurs, both from the Alivio line, the whole system is very smooth and effective. The shifters themselves are easy to use and unlikely to jam. The derailleur system needs minimal maintenance, no more than any other derailleurs. 

You’ll have the options and versatility to need for even the most technical trails, and the flexibility to handle hills with ease.

You’ll also be getting a Shimano brake and rotor system. The disc brakes are highly effective and fast to respond. The hydraulic disc brake system is also a significant improvement over the v-brakes or mechanical disc brakes that are much more common on cross-country bikes in this price range. 

This brake design is also very low on maintenance requirements since you’re extremely unlikely to get dirt and debris in any of the moving parts. 

Since the internal routing system helps to protect the wiring, it’s also much easier to perform any needed maintenance or to set up new cabling systems. 

The biggest thing you’ll need to watch for if you’re used to other braking systems is that this system is likely to be more responsive than you’re used to. Start slow and experiment to see how much pressure you need to get the speed modulation you’re going for. 

Customer Reviews

Riders who’ve played with this bike for a while to see what kind of performance they can expect consistently come back saying that the X-Caliber 7 exceeded their expectations. Relatively similar to the Trek Marlin line, another slightly more affordable entry-level mountain bike from Trek, this system features just a few upgrades that help it last longer as your experience and skill both grow. 

While this bike might not have the optimization of a more expensive mountain bike, it still performs well enough to take you down advanced technical trails and even to races and other competitions. 

With the advantages of a few minor upgrades to the components over other similarly priced bikes, users consistently report improved performance with very few problems or noticeable shortcomings. 

Alternatives

No good bike review is complete without taking a look at some of the competitor models to see how each bike stacks up in a head to head comparison. These bikes are all relatively similar in design, target consumer, and core features, but each has its own strengths and weaknesses. 

Trek X Caliber 7 vs 8

It makes sense to start by looking at the latest release in the X Caliber line. The X Caliber 8 is the 2020 model just released for this line and does feature some components and design improvements that make it a better option for some riders. 

Price-wise, these two are relatively similar. The X Caliber 7 is usually the more affordable of the two. But, as demand for the older model has increased, and when the X Caliber 8 begins to go on sale, that may not always be true. 

In the X Caliber 8, Trek has upgraded the driveshaft to Shimano’s Deore line, giving you 20 gears instead of 18. In terms of maintenance and performance, the Deore is similarly low-effort and high-performing, but the added flexibility makes it a better overall system. 

They’ve also slightly improved the fork, although the models are very similar, the newer fork system offers just a little more effectiveness in your suspension. 

Overall, both models are great beginner bikes. But, if you can afford a couple hundred more to get the latest system, it’s probably going to last longer and work better as a long-term bike. 

Trek X Caliber 7 vs Roscoe 7

This is another interesting comparison because these two Trek lines actually use the same frame. However, the components and tires that come on each model aren’t very similar at all. 

The biggest difference between these models is how you want to ride them. The X Caliber 7, and the whole X Caliber line, are designed for speed and precision. These are real trail-eaters that don’t need much encouragement to reach top speeds. 

The Roscoe, on the other hand, is designed for a slightly heavier, slacker, grippier riding experience. That makes them slower than the X Caliber in general, but also much steadier. 

If you like your trails loose and fast, look to X Caliber models. Looking for a slightly slower but more controlled ride, the Roscoe 7 might be your better bet. 

Price-wise these bikes are so similar that it shouldn’t be much of a deciding factor one way or the other. 

Trek X Caliber 7 vs Marlin 7

The X Caliber 7 and the Marlin 7 are both designed for largely the same market. They’re reasonably affordable entry-level XC mountain bikes that are designed for the best possible performance at a low-price range. 

However, the Marlin 7 is a couple of hundred dollars cheaper than the X Caliber 7. While the components lists are similar, the Marlin 7 is a step down in almost all component categories. 

That doesn’t mean that it’s not a good high-performance bike, the Marlin 7 is still a great entry-level bike. 

However, you will get serious performance improvements, both in speed and in shifting ability, if you can afford to upgrade to the X Caliber line.  Check our guide to marlin 7 here.

Overall, the X Caliber 7 might not be the best XC bike out there, It’s not even the best XC bike in its own model line. That doesn’t mean that it’s not a solid entry-level option and one that’s particularly well suited to fast an adventurous rider who is looking for a bike that can grow with you. 

Its frame is designed to be easy to upgrade, highly durable, eye-catching, and most of all, fast and extremely efficient. 

If you’re looking for a fast mountain bike that competition ready, but it isn’t too expensive, the X Caliber 7 is a good choice.
