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 aluminum frame, a RockShox Judy SL 100mm suspension fork with a TurnKey lockout and an air spring that’s lighter and more adjustable than a coil spring, tubeless ready wheels with Boost141 hub spacing, and a Shimano Deore 1×12 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 Shimano Deore drivetrain. Plus, it’s equipped with durable, lightweight alloy rims that save weight and are easy to upgrade to tubeless.
