TREK X-CALIBER 8

It’s right for you if…

You’re looking for a fast mountain bike for singletrack—one that’s fully capable of taking on races, marathons, and competitive group rides. You want something that is reliable and fun with dependable, lightweight parts.

The tech you get

A lightweight aluminum frame, a RockShox Judy SL 100mm suspension fork with a TurnKey lockout and an air spring that’s lighter and more adjustable than a coil spring, tubeless ready wheels with Boost141 hub spacing, and a Shimano Deore 1×12 drivetrain with a wide-range cassette.

The final word

With X-Caliber 8, you’re getting a performance frame paired with performance parts, like a RockShox air fork and 1x Shimano Deore drivetrain. Plus, it’s equipped with durable, lightweight alloy rims that save weight and are easy to upgrade to tubeless.

1. It has the price of a more basic hardtail, but the parts and performance of a more expensive one
2. The frame is fully compatible with higher-end parts, like race wheels and a dropper post, if you ever find the need to upgrade
3. Smart Wheel Sizing means you’ll get the fastest wheel that fits (29˝ wheels on larger frames, 27.5˝ wheels on smaller frames)
4. The 1x drivetrain delivers a wide range of gearing with the simplicity of a single shifter

   How tall are you?

   To measure your height, stand straight up, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

   What is your inseam?

   How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inseam measurement. Your inseam is very important to your final bike size so please measure carefully.
