Niner’s AIR 9 RDO is designed with cross-country racing in mind. With the culmination of over ten years of research, design, and rigorous lab and real-world testing, The AIR 9 RDO is ready to tackle your short track, cross-country, marathon, or ultra-endurance goals. The AIR 9 RDO is beautiful from the inside out because of Niner’s Carbon Compaction System, which utilizes rigid internal molds for tighter, more consistent carbon compaction and precise wall thicknesses, or more precisely: more strength with less material. The AIR 9 RDO accommodates up to a 120mm-travel fork for stable, precise steering and handling that lets you relax, stay confident, and focus on being fast.
The AIR 9 RDO 2-Star brings you the best cross-country frame Niner has to offer with a reliable, practical build kit. The RockShox Reba RL Air fork dutifully soaks up 120mm of trail chunder and firmly sticks the fast-rolling and tenacious Maxxis Ikon tires to your line of choice (the fast one). SRAM delivers a streamlined, thorough range of gears in a precisely shifting GX1 drivetrain so you can effortlessly find the gear you need while keeping your cockpit clutter-free. And, SRAM’s DB5 hydraulic disc brakes deliver the power and modulation to flirt with lockup while maintaining traction, translating into higher speeds less momentum loss.
