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.

A lightweight Alpha Gold Aluminium frame, a RockShox Judy Silver 100 mm suspension air fork with a remote lockout and a Shimano XT/SLX 1x12 drive train 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.

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.

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
The frame is fully compatible with higher-end parts, like race wheels and a dropper post, if you ever find the need to upgrade
A remote lockout lets you lock out the fork on flats without taking your hands off the bars
The 1x drive train delivers a wide range of gearing with the simplicity of a single shifter

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.

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.

Handlebar-mounted controls let you lock out your suspension on the fly as you switch terrains.

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.

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

The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
