High tech frame
The Alpha Gold Aluminum 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 out back.
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.
Shimano XT
Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Suspension lockout
Locked suspension means your fork remains inactive, increasing pedaling 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.
Blendr-compatible stem
Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.
