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 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.
Niner built the 4-Star AIR 9 RDO to maximize speed, minimize weight, and maintain durability and ease of maintenance. The Fox 32 Float Factory fork delivers 100mm of smooth front-end travel, thanks to the on-the-fly compression damping adjustability of FIT4 and the seemingly frictionless action provided by Kashima-coated stanchions. The Niner Carbon XC wheels are lightweight and resilient, and mate nicely with fast-rolling, corner-devouring Maxxis Ikon tires. Enjoy the solid shifting action of SRAM’s X01 1 x 11-speed drivetrain, with a carbon crank, and a narrow-wide tooth profile for minimal weight, maximum power transfer, and unbeatable chain control. SRAM Guide RSC brakes give you immediate modulation with adjustable lever throw. Finally, Niner decked out the 4-Star with their carbon RDO stem, seatpost, and handlebar for the ultimate in lightweight strength, making the AIR 9 4-Star your perfect victory lap vehicle.
