Details

X-Caliber 7 is the perfect entry point to fast cross country riding and racing. It's a fully capable hardtail mountain bike with expert tech where it matters most, like in the lightweight and durable alloy frame, 100mm RockShox fork, Shimano drivetrain, and hydraulic disc brakes.

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.

Why you'll love it

- 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
