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 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. In the revamped edition the X-Caliber 8 does away with a front derailleur and replaces it with a tidy 1x12 SRAM SX groupset. This setup still gives you the same great range of gears but prevents the front derailleur from getting plugged up with mud when the weather is challenging. So get ready for fun days out that will take you to the edge of your limits.
It's right for you if...
You're looking for a fast mountain bike for singletrack – 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.
The tech you get
A lightweight Alpha Gold Aluminium frame, a RockShox 30 Silver 100 mm 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, Shimano hydraulic disc brakes and a smooth, efficient SRAM SX Eagle 1x12 drivetrain with a wide-range cassette.
The final word
With X-Caliber 8, you're getting a performance frame paired with performance parts, like a RockShox air fork and 1x SRAM Eagle drivetrain. Plus, it's equipped with durable, lightweight alloy rims that save weight and are easy to upgrade to tubeless.
