Overview
About this bike
Niner's R.O.S. 9 Singlespeed features a slack head tube angle, but it's no slacker when it comes to shredding the gnarliest trails. With its 4130 steel frame giving you the durability and stellar ride quality you've come to expect, the R.O.S. 9's aggressive attitude comes from the short chainstays that make it a whippy beast in tight singletrack, while the slack head tube angle keeps everything under control at high speeds. Up front, a RockShox Revelation RCT3 gives you cushy landing gear for those natural kickers and drops, and the Stan's NoTubes Rapid wheels make rough rocks and roots insignificant rattles. And with a Niner Cogalicious cog out back, you get the perfect gear for ups, downs, and everything in between.
