It's right for you if...
You're new to mountain biking and want a high-value bike that's perfect for local XC trails and even racing. You want to invest in the parts that make a difference in performance—frame, suspension, and brakes—and want a bike you won't immediately outgrow as your skills advance.
The tech you get
A lightweight Alpha Gold Aluminum frame, a RockShox 30 Silver 100mm suspension fork with a lockout, a dependable 2x9 Shimano drivetrain, Shimano hydraulic disc brakes, and wider Boost141 hubs for increased wheel strength and better tire clearance. This hub size is standard for higher-end wheelsets, making it easy to upgrade your wheels if you're looking for a fast way to increase performance.
The final word
X-Caliber 7 is a great cross country mountain bike at a great value. It has the same features found on higher-end bikes—like internal cable routing, dropper post compatibility, a tapered head tube, and Boost hub spacing—all on a platform that's easy to upgrade down the line.

- It gets you into the world of cross country riding and racing at a great price, and it's a mountain bike that can grow with you as your skills advance
- The sleek internal cable routing gives you clean looks, protects your cables, and makes it easy to upgrade to a dropper post for even more capability
- Smart Wheel Sizing means you'll get the fastest wheel that fits (29˝ wheels on larger frames, 27.5˝ wheels on smaller frames)
- The RockShox air fork has a rebound adjust and can be tuned to the rider’s weight, and it’s way higher quality than what you’d normally get on an MTB at this price

Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Locked suspension means your fork remains inactive, increasing pedaling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
Going for a long ride? Rack mounts make carrying accessories a breeze.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
