Take charge of your ride with this Reynolds 853 steel frame designed around Niner's [R]evolution trail geometry. Ride it hard. Ride it fast. After all, it's made from a truly time-tested material that's been air hardened and heat treated. The efficient, yet compliant ride quality of the SIR 9 hearkens back to a simpler time. A SRAM X01 Eagle 1x12 drivetrain and Guide RSC brakes provide wide-range gearing with ample stopping power in a lightweight combo, and a Fox 34 Float Factory 120mm fork, Stan's Arch wheelset, and a KS Lev Integra dropper seatpost create a solid platform for getting rowdy on the trail. Niner knew you'd also enjoy loading this steel steed for a weekend of bikepacking adventure so they added 18 mounting points to accommodate those needs. However you choose to use the SIR 9, its simple design will inspire a renewed desire for exploration and reward you with that comfortable ride only a high-grade steel hardtail can supply.
