Where XC bikes get serious
X-Caliber is a high-value cross country mountain bike that performs way out of its class on singletrack and long XC rides. It has a lightweight aluminum frame, quality parts, and more versatility than you can shake a spoke at.
Whether you’re lining up at your local XC races or chasing daylight after work, this bike will give you speed and efficiency for your best days on the trail.
Built for speed
Every X-Caliber has fast-rolling tires and front suspension that locks out for efficiency on climbs and sprints, plus simple 1x drivetrains with a wide range of gears for scampering up hills and racing to the finish line.
The best fit for every rider
X-Caliber comes in seven frame sizes to suit any height, and Smart Wheel Size ensures every rider gets the fastest wheel that fits. Larger sizes have bigger 29˝ wheels and smaller sizes have more proportional 27.5˝wheels.
Ready for accessories
X-Caliber’s integrated rack and kickstand mounts make it easy to outfit your bike for any adventure, which come in handy if your MTB is also your commuter. The frame is also set up to accept an internally-routed dropper post.
