X-Caliber 9 is the top-end model in the X-Caliber family. It's a fully race-ready cross country mountain bike built with parts designed to compete. A RockShox Recon fork, a 1x12 Shimano XT/SLX drivetrain, and a wide-range cassette make it a great choice for fast singletrack riders who want a great bike that's ready to race right out of the box.

Why 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 awesome 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, if you ever find the need to upgrade

The 1x drivetrain delivers a wide range of gearing with the simplicity of a single shifter

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 aluminum frame, a RockShox 100mm suspension air fork, 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 tire clearance, and a dropper post for getting low on descents.
