favorite_borderWhy you'll love it
- It's a great bike for someone who's just getting into serious racing: you get high-end XC parts on an incredible frame with enough cash left over for entry fees
- There's nothing as sweet as a silent ride: the clutch rear derailleur prevents chain slap, even in the rough
- Front and rear Boost hub spacing opens the door for high-end wheel upgrades
- The 31.6 mm seat tube gives you the option to install a dropper post when you want to tackle rowdier terrain
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.
Handlebar-mounted controls let you lock out your suspension on the fly as you switch terrains.
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.
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.
