Overview
About this bike
For a snappy whip that caters to podium-driven racers and personal record chasers alike, the AIR 9 RDO delivers lightweight responsiveness you'll appreciate on sustained, leg-busting efforts. The carbon frame's refined tubing shapes and modern geometry tweaks lend the AIR 9 RDO a smooth ride with powerful acceleration capability, while Boost hub spacing keeps the chainstays short while allowing for stronger wheels, giving you impressive tracking at speed over rough terrain. The 2-Star build features SRAM's value-packed GX Eagle 1x12 drivetrain, powerful Guide R hydraulic disc brakes, and a RockShox Reba RL Solo Air 100mm fork that all come together to make a bike that goes just as hard as you.
