Niner SIR 9 Frameset - 2020

Take charge of your ride with this Reynolds 853 Steel frame designed around Niner´s [R]evolution trail geometry which begs the rider to push their limits. 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 harkens 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.
