It's right for you if...
You measure your rides in speed and distance, and want a fast XC bike that will help you cover more trail in less time. You race, or you could see yourself getting into racing, so you want a hardtail with competition-level parts that can give you an advantage on the trail.
The tech you get
A lightweight aluminium frame, a RockShox Recon Gold RL100 mm suspension air fork and a Shimano XT/SLX 1x12 drivetrain with a wide range of gears for easier climbing. Plus, tubeless-ready wheels with wider Boost141 hubs for increased wheel strength and better tyre clearance, and a dropper post for getting low on descents.
The final word
The X-Caliber 9 is a speedy, nimble and efficient XC hardtail that's perfect for riders with a racing pedigree and anyone who dreams of covering epic distances out on the trail.

- The frame is fully compatible with higher-end parts, like racing wheels, if you ever find the need to upgrade

Features
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.
Suspension lockout
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.
Blendr-compatible stem
Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.
