Its fantastic UHC full-carbon frame and tapered fork hold your line, damp the ruts, and leave you feeling fresher than ever at the end of the race. The CX-specific geometry is dialed to perfection and there's even a flattened top tube section for easy shouldering. SRAM's crisp CX1 drivetrain streamlines your race with eleven 'cross-friendly gears and no risk of a dropped front shift. Whether you're flying over hardpack or slogging through the mud, TRP's Spyre mechanical disc brakes scrub speed quickly and smoothly. And, Mavic Aksium ONE wheels with Vittoria rubber spin through the muck and grab onto the terrain for exceptional cornering. It all adds up to a ride that'll bring a huge grin to your mud-covered face.
