Its innovative technologies include flat-mount disc brakes with 12mm front and rear thru-axles and the vibration-damping D-Fuse integrated seatpost. The oversized and tapered OverDrive 2 steerer tube boosts cornering precision. And the MegaDrive downtube and PowerCore bottom bracket deliver precise handling and class-leading pedaling efficiency.
