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

X-Caliber 7 has a lightweight Alpha Gold Aluminum frame, RockShox fork with 100mm of travel and a lockout feature, a dependable 2x9 Shimano drivetrain, 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.

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.
