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, 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
A lightweight Alpha Gold Aluminium 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 wheel sets, 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 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
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.
Bontrager stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.
Going for a long ride? Rack mounts make carrying accessories a breeze.
