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 time without linkages and complicated shock settings. A time where all the energy you put into the pedals moves you forward. The PF30 bottom bracket allows you to run a standard press fit bottom bracket or, if simplicity is your thing, throw in an eccentric bottom bracket and run singlespeed. A hidden plate inside the chainstay yoke stiffens and strengthens in order to improve power transfer, and 18 mounting points allow you to pack it full of the things you need for a long weekend of mountain bike adventure.
