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.
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.
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
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.
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 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.
