JB Racer

Pure XC heart and soul.

Born from years of riding cross-country singletrack, the JB Racer is a great race bike or all around cross-country rig. The geometry is dialed for shredding ribbons of fast singletrack and there’s lots of tire clearance for riding in the mud. Built light and right for all-day rides to the highest mountain passes. We like it best with the optional internal brake line routing.
