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.
favorite_borderWhy 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
- Smart Wheel Sizing means you'll get the fastest wheel that fits (29˝ wheels on larger frames, 27.5˝ wheels on smaller frames)
Locked suspension means your fork remains inactive, increasing pedaling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Internal derailleur routing
Sleek ports at the head tube and near the seat tube let you route your derailleur cables through the frame to keep your bike running smooth and clean.
Going for a long ride? Rack mounts make carrying accessories a breeze.
Alpha Gold Aluminum
Our high-performance lightweight aluminum is continuously cold extruded and butted, and formed into manipulated tube shapes to balance strength and weight saving.
Extended size range
A wider range of sizes than the industry standard provides more option for everyone, from tallest to shortest and all those in between. Because everyone deserves a great ride.
Dropper post internal routing
Not ready for an internally routed dropper post now, but want to keep your options open? Select frames are equipped with the proper entry and exit points to accommodate internal routing for a Stealth seat post.
Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability. We call it G2 Geometry, and it's why our 29ers handle better than anyone's.
