SIR 9: rugged, reliable, comfortable Reynolds 853 steel. There’s a new bike in town. It’s built to last and not let you down. When you’re spinning up the steeps, bombing down the backcountry and grinding out the final miles as the sun sinks into the horizon, you need a bike you can trust. A comfortable, capable, hand-built bike made from proven, air-hardened, heat-treated steel. That’s right, steel. Because Steel Is Real and it’s fully optimized in the SIR 9.

Expect the best from SRAM’s GX Eagle drivetrain. Mated to Niner's SIR 9 frame and FOX 34 Factory suspension, every feature of this adventure-seeking singletrack slayer is fully optimized.
