Trek 2023 X-Caliber 9

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 straight out of the box.

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 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 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 racing 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

Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
