Details
The SIR 9 is a comfortable, capable, hand-built bike made from proven, air-hardened, heat-treated Reynolds 853 steel. 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.
Expect the best from our fan-favorite 3-Star SRAM GX Eagle kit. Mated to the SIR 9 frame and FOX 34 Float Factory suspension, every feature of this adventure-seeking singletrack slayer is fully optimized.
