X-Caliber 9 is the top-end model in the X-Caliber family. It's a fully race-ready cross-country mountain bike built with parts designed to compete. A RockShox Judy Silver fork with remote lockout, a 1x12 Shimano XT/SLX drive train, and a wide-range cassette make it a great choice for fast singletrack riders who want a great bike that's ready to race straight out of the box.
