'Medium' is intuitive. '17.5' is not. Alpha sizing makes it easier for you to know what Trek mountain bike will work for you. A lot of other brands also use alpha sizing, and if you ride a medium in a different brand, you’ll probably ride a medium Trek as well.
Trek frame size used to be measured by the length of the seat tube. But modern mountain bike geometry is based on reach, not seat tube length. Alpha sizing is simpler and helps you find the right fit by the measurement that matters most.
| Alpha size | XS | S | M | ML | L | XL | XXL |
| Frame size | 13.5 | 15.5 | 17.5 | 18.5 | 19.5 | 21.5 | 23 |
Trek offers mountain bikes in a wide range of sizes to ensure the perfect fit for all riders. That includes an XXS with increased standover height, an ML (medium-large) perfect for those in-betweeners in the middle of the sizing bell curve, and an XXL for taller riders who often struggle to find a bike that’s big enough.
Not all sizes are available on all models, but Trek’s extended size range will help any rider find a frame that fits better from the start and requires fewer changes to the cockpit.
The easiest way to determine your frame size is by height, but many riders find that they are between sizes. Choosing to go up or down a size depends on your personal riding style and body proportions.
A bike with a longer reach will have a longer wheelbase. That makes it more stable, especially on high-speed descents. That’s great for riders who like to plough through rather than pop over rough stuff on the trail. If you have a relatively long torso or arms for your height, you may find that a longer reach gives you a roomier, more comfortable cockpit.
A bike with a shorter reach will have a shorter wheelbase. It’s not as stable, but it’s more nimble and easier to flick around. That’s great for riders with a more playful, active riding style who like to get off the ground and whip their wheels around. If you have a relatively short torso or arms for your height, you may find that a shorter reach makes it easier for you to hold the handlebars comfortably.
