Niner One 9 RDO 2-Star SS Rigid

Niner’s ONE 9 RDO is a flat-out fast, singlespeed-specific, cross-country racing bike. Niner melded the reduced diameters and trimmed profiles of the ONE 9 with the stiff, lightweight carbon chassis of the AIR 9 RDO. The rear brake mount is tucked inside the curved stays to distribute twisting forces evenly, permitting smaller caliper mounts and decreased wall thicknesses. Even the headset races in the head tube are made of molded carbon to shave grams wherever possible, resulting in a frame that is very lightweight, very fast, and ready for your next punishing race. The ONE 9 RDO employs Niner’s Biocentric II bottom bracket, which allows simple, secure single-speed set-up and gearing adjustments without brakes or wheel position adjustments; it also enables you to customize the bottom bracket position for a perfectly dialed geometry.

The 2-Star SS Rigid keeps you connected to the trail using the Niner RDO full carbon fork that provides crisp, exact steering while maximizing the trail-damping properties of carbon. A pair of no-nonsense SRAM DB5 brakes halt your progress with precise modulation, and Maxxis Ikon tires roll fast and bite hard through loose corners. It’s a ready-to-rip, stripped-down race rocket that’ll go as fast and hard as you can.
