Trek alpha sizing for MTB – what is it?

The old-school approach of measuring the frame size of Trek bikes is a thing of the past. With newer inventions and modern bike geometry, alpha sizing is used in place of numeric sizing on Trek mountain bikes.

Why is alpha sizing important?

1. Easier approach

Instead of using size numbers like 19.5, the sizes can be classified into S, M, ML, L, XL, and XXL. So, someone with a 17.5 size can go for the medium and a 19.5 is a large size. You don’t have to keep a tab on numbers; instead, the alphabet makes it easier.

2. Measurement based on reach

In earlier times the frame size measurement of Trek bikes was solely based on seat tube length. Things have changed, and modern mountain bike geometry focuses more on reach as of now. Hence, alpha sizing measures what matters and is a more simplified way of measuring bike size.

Trek sizing – virtual vs actual

This can puzzle you a bit as they both are somewhat similar yet there is a subtle difference. Actual size can be termed as the overall length of the seat tube from the center of the bottom bracket to the center of the top tube intersection with the centerline of the seat tube.

On the other hand, virtual sizing is the overall length of the seat tube ranging from the center of the bottom bracket to the mid-point of the imaginary horizontal top tube in which it connects with the seat tube.

If I had to give you an example, a bike might have a virtual size of 18.5 and an actual size of 17.5. This means that the bike size feels like 18.5, but in actual sense, the frame size is 17.5. It doesn’t make much of a difference as it is there only to let you know what it is (actual size) and what it looks like in size (virtual size).

People also ask

Trek 17.5 frame size – what does it mean.

A 17.5 frame size is considered an M size (Medium) in terms of alpha sizing. Any individual who is 161-172 cm or a height of 5’3.4”-5’7.7” . If you are within this height range, going for a medium size shall be the right choice.

Trek medium frame size is for what height?

A medium size frame size (17.5) is ideal for a person with a height between 5’3.4”-5’7.7 ”. In centimeters, it is ideal for those around 161 to 172 cm in height.

Trek 24-inch bike is for what age?

When it comes to children, their bikes are measured in terms of wheel size instead of the standard frame size. These kid’s bikes have a size range between 12-26 inches, depending upon the height of the kid.

As far as a 24-inch wheel size is concerned, any kid between the ages of 8-11 can go for a fun ride with it. Some of the popular 24-inch bike models are Trek Roscoe 25, Wahoo 24, Trek Precaliber 24 , etc.

Trek 26-inch bike is for what height?

A 26-inch wheel-size bike is for kids with a height of 4’9”-5’3” (146-160 cm) . Wahoo 26 is a prime example of a bike in this category.

Trek 20-inch bike is for what age?

Trek 20-inch bikes are for children between 5 to 8 years of age. Additionally, if they are within the height of 3’9”-4’6” , it should be suitable for them.

Are Trek bikes good?

Trek bikes are considered to be extremely good and solid in build. It is known to be the number 1 performance bike brand all over the globe. Having its humble beginning in the year 1976 in Waterloo, Wisconsin, it has turned into the largest bicycle manufacturer all over the world. With an array of bikes ranging from, mountain, road, electric, and kids bikes, there is a lot to choose from a mammoth list.

How much is a used Trek bike worth?

It depends on a lot of factors in terms of how old the bike is, the year of production, which model, and a lot more. However, it can be within $1000-10,000 (depending on the model and other factors) .

Where are Trek bikes made?

The majority of their bikes are manufactured in Taiwan, China, Netherlands, and Germany too.

Why are Trek bikes so expensive?

Usually, the bike brand prefers top-tier components, suspensions, and frames that are ahead of its competitors. This results in additional costs that can be seen in the price tag and also many top-end Trek bikes are custom-made with less production, leading to being more expensive.

Trek bikes are a class apart in many ways with a range of bikes on offer for its fans across the world. Choosing the right size for you can be tricky, but this is where the Trek frame size chart comes to the rescue.

Trek as a bicycle brand might be on the costly side, but they punch above its weight to provide top-class bikes for the masses. I am always someone who roots for quality, and Trek provides what I need.

One comment

Thanks for your informative post. I really like the Trek alpha sizing for MTB because Trek frame sizes use alpha sizing rather than the usual inches or centimeters (cm), and they usually have a certain range of measurements.

Trek Fuel EX Sizing Help

• Add to quote

I’m on the verge of purchasing a 19 Trek Fuel EX 8, but I’m having trouble trying to decide between the 18.5 and 19.5. Below are my deminsons Height: 5 feet 11” 180 CM Inseam: 33 Apex: +1.5 wing span 6 feet 1/2 I’ve read through a few posts mentioning sizing and honestly I’m not sure which one I should get. Based on the trek website and the new sizing chart on the fuel ex 8 page being 180 cm I fall a littte outside of the 18.5 (170-179cm / 5’ 6.9” - 5’10.5”) and more so on the backend of the 19.5 (177-188 / 5’9.7” - 6’2.0”). I’ve test ridden both sizes several times and while the bike shop sides more so with the 19.5 based on my size, the 19.5 feels a tab big. Granted the 18.5 is really only 1/2 inch shorter than 19.5 based on the ETT measurement. This is my first MTB as I’m used to riding a road bike (56cm Trek Domane) so I’m not sure if the bike should feel big. On the 19.5 I’m not overly stretched out and I still have a some bend in my arms, but it just feels like it might be a smig too big. On the 18.5 The bike feels just about right, not too small but not too big. My arms have a good bend and I don’t feel like I’m leaning as much as on the 19.5, but while it might feel better I have some concerns going with a smaller 18.5 over the 19.5. since I’m more so used to Road biking and not used to MTB I’m concerned that a smaller bike will have trouble descending or even climbing. I don’t want to go OTB and understand that bigger bike helps put my weight back better. Also on bigger bike I understand I have more room out of the saddle climbing. But on the 18.5 I feel like I have a little better control and feel like I can wip the bike around a little more easily. One bike shop says that the big feeling is normal and that I should be on the 19.5, while another shop tells me the if I’m between sizes I should go smaller as I’ll have more control over the bike. I’m sure on the DH the 19.5 would probably be great and out of the saddle I might have a little more room to climb. On the 18.5 I feel like I have a little more control and want to wip the bike around a little more. My wife and I did demo the 19.5 on some local trails and it felt ok, but since the shop doesn’t have the 18.5 to rent, I’ve only been able to test ride the 18.5 around the parking lot and over some curbs and drainage ditches, so I’m not sure how it going to handle on the actual trail and going DH. At this point I’m not sure which way I should go since I fall just outside the 18.5 on the trek sizing chart. I do understand that I can always move the saddle up or back and buy a bigger or smaller stem. Just hoping some of you might have some advice and expirence. thanks in advance.  

I am 6 foot with an inseam of 34.4----can go 19.5 or 21.5--------no way for the 18.5----way to small for you---my 2 cents-----historically treks have run small---do a search on these forums and you will see this topic over and over---you do not want to move the saddle back---that moves your weight where you do not want it over the back wheel and slackens the already slack seat tube angle---again just me but 19.5  

We’re a family of Trek Fuel riders and have an 17.5 wife 5’5”, 18.5 me 5’9” and 21.5 son 6’1” I would say 19.5  

19.5 all the way. Trek's are neither long or short, kind of middle of the road. I'm 6'2" with short 32" inseam, and ride a 21.5.  

Yep. Fuels run small. I think you need 19.5. I'm 6'1" -- 32" inseam, long arms and torso -- and ride an 2018 in size 21.5. I ordered my first Fuel, a '16, online in 19.5 based on the Trek size chart and measurements from the bike I had at the time. Too small. I had to run a longer, higher stem to make it work, and still had the bars lower than I wanted and the seat a bit too far back. Much happier on the 21.5.  

Personally I prefer a smaller bike. You can make a smaller bike feel larger but it’s hard to make a larger bike feel smaller. I’m 5’8” and have a 17.5. Btw where is the stem adjusted on the bikes you tested? That gives some adjustment also and will change your riding position.

I want to thank everyone for there feedback as I really value your input and experience. The shop where I was looking at is cycling out there 2018 rental models and should have the new 2019 Fuel FX rentals in stock here in the coming weeks. I think I'm going to do one more rental ride on the local trails on the 19.5 since they won't have an 18.5 to rent, just 17.5 and 19.5. I'll ask if they can shorten the stem to a 50mm stem as I think the stock stem is 60mm, and or even move the seat forward a little bit before I take it out on the trail to see how that feels. I realize that parking lot tests are nothing compared to actually taking it on the trail and getting a feel climbing and descending. Again I appreciate all your input and advice.  

Based on your road bike being 56cm I would go with the 19.5. Sent from my 9020A using Tapatalk  

I am now on my second Trek MTB and am 6' with a 33" inseam. My first Trek was a hardtail in 18.5" that was used to try trail riding and also for gravel roads. It worked out well to learn on and on gravel but on trails it was too small with too much weight on the front. When the 19 Fuel EX8 came out I picked one up in a 19.5" and after a few hundred miles I think I could have possibly gone up to a 21.5" in this bike. On the 19.5" I feel like I am more on top of the bike than in the bike.

Earlier this year, the Fuel EX received rapid fire updates that first introduced a 27.5+ version then quickly made it the standard model by adding 29er wheels and tires for most of the stock builds. The frame was all new for both, bumping travel to 130mm, and it effectively did away with the standard 27.5 …

A 27.5in Fuel EX joins the existing 29er, but the real story is a leap forward in suspension damping

The RE:aktiv rear shock combined with DRCV is a great combo — plush in descend mode while firm and supportive in climb, with an excellent mix of both in trail mode.

Long stems on the larger sizes seem at odds with the trail-orientated set-up.

Quiver Killer Trail Bike

The Fuel EX is the definition of a modern trail bike, and is Trek’s most well-rounded MTB. With the introduction of Trek's Knock-Block technology and a "straight shot" downtube, this generation of the Fuel EX frame got noticeably stiffer in all the best ways. Another great change was the increase in tire clearance, allowing you to run wider tires for better traction whether 27.5" or 29"! With more travel than the Top Fuel and less travel than the Remedy, it’s capable on descents and quick on climbs. Meet your ticket to fast and fun.
