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 Aluminium frame, a RockShox 30 Silver 100 mm suspension fork with a lockout and an air spring that's lighter and more adjustable than a coil spring, a dependable Shimano 1x10 drive train with a wide range of gears for easier climbing and tubeless-ready wheels with wider Boost141 hubs for increased wheel strength and better tyre clearance.
The final word
X-Caliber 7 is a great cross-country mountain bike at 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)
- 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
- The 1x drive train delivers a wide range of gearing with the simplicity of a single shifter
Built for speed
X-Caliber is a classic XC hardtail with quick-handling geometry, weight-conscious parts and just enough suspension to take the edge off bumps. These models are built for efficiency, making them great for racers or anyone else who wants to cover more ground in less time.
High tech frame
The Alpha Gold Aluminuum frame is packed with features that make your ride better. A tapered head tube gives you more precise, confident handling on the front end, while Boost 141 rear hub spacing gives you shorter chainstays for more nimble handling at the back.
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 pedalling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
Internal cable routing
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
Going for a long ride? Rack mounts make carrying accessories a breeze.
Rear kickstand mount
Chainstay mounts make it easy to install a rear kickstand that stays out of your way and supports bikes of all sizes. No more laying or leaning.
Internal dropper compatible
Internal routing ports make it easy to add a dropper post upgrade that lets you lower your saddle on the fly so it's out of your way for tricky sections of trail.
