Built for eager weekend hammerheads and professional racers alike, the AIR 9 RDO delivers lightweight responsiveness you'll appreciate on sustained, leg-bursting 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. This 5-Star build features a no-compromise list of components, including SRAM's X01 Eagle 1x12 drivetrain and powerful Guide Ultimate hydraulic disc brakes, a fabulous Fox 32 Float SC Factory 100mm fork, and Niner's own carbon RDO seatpost and handlebar for race day performance.
