Features

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 aluminium frame, a RockShox Judy SL 100 mm 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 1x12 drivetrain with a wide-range cassette.
The final word With the 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.
The Alpha Gold Aluminuum frame is packed with features that make your ride better. A tapered head tube gives you more precise, confident handling on the front end, while Boost 141 rear hub spacing gives you shorter chainstays for more nimble handling at the back.
X-Caliber is a classic XC hardtail with quick-handling geometry, weight-conscious parts and just enough suspension to take the edge off bumps. These models are built for efficiency, making them great for racers or anyone else who wants to cover more ground in less time.
It has the price of a more basic hardtail, but the parts and performance of a more expensive one.
The frame is fully compatible with higher-end parts, like race wheels and a dropper post, if you ever find the need to upgrade. Smart Wheel Sizing means you'll get the fastest wheel that fits (29˝ wheels on larger frames, 27.5˝ wheels on smaller frames). The 1x drivetrain delivers a wide range of gearing with the simplicity of a single shifter
