Trek designed the X-Caliber series to help you go faster and further than ever before on your favourite trail, single track or upcoming competition. Built with lightweight Alpha Gold Aluminium, the Caliber is as strong as it is lightweight and stiff, meaning you're not slowed down up the hills but you have the strength to take on whatever the trail has to throw at you! RockShox's air fork provides 100m of travel through the front suspension fork but also has a lockout feature which is handy when you're on the road and efficiency is more important than taking the pinch out the trail. High-quality parts such as Shimano's Deore/XT rear mech and 32/22 RaceFace cranks all help take you to the next level. Finally, the X-Caliber is accessible with rear cargo racks, meaning on your next commute back from work why not pass-by your favourite single track? The opportunities are endless.
What do you want?
You're looking for a fast mountain bike for single-track – one that's fully capable of taking on races, marathons and competitive group rides. You want something that is reliable and fun with dependable, lightweight parts.
A lightweight Alpha Gold Aluminium frame, a RockShox 30 Silver suspension fork with a lockout and an air spring that's lighter and more adjustable than a coil spring, Bontrager Kovee Tubeless Ready wheels with Boost141 hub spacing and a smooth, efficient Shimano Deore/XT 2x10 drivetrain with a Shimano XT Shadow rear derailleur, which stays tucked out of the way to avoid snagging on trail debris.
With the X-Caliber 8, you're getting a performance frame paired with performance parts, like a RockShox air fork and a rear derailleur that's the gold standard for MTB performance and reliability. Plus, it's equipped with durable, lightweight alloy rims that save weight and are easy to upgrade to tubeless.
