The S.I.R. 9 is the most versatile bike in the Niner stable, fusing the "steel is real" feel of Reynolds tubing with the ability to run the frame as either a geared bike or single speed. The S.I.R. 9 uses the same custom drawn Reynolds 853 tubing as the M.C.R. 9 and combines it with Niner's ultra-light eccentric bottom bracket.

Niner has revamped their entire line over the past year or so, and the latest bike to receive a reboot is the SIR 9 hardtail. The SIR has been in Niner's catalog pretty much since the beginning as a classic XC steel hardtail. Then, a few years ago Niner introduced the ROS 9, a steel hardtail with much more aggressive intentions.
