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.

SRAM does it again with this 2-Star SX Eagle parts kit. It's a wallet-friendly yet high-performing parts kit. Mated to our SIR 9 frame and Marzocchi suspension, every feature of this adventure-seeking singletrack slayer is fully optimized.
