Product Details

NN05 Niner R.O.S. 9 4-Star X01

On the outside, Niner's R.O.S. 9 looks like your typical steel hardtail; on the inside, it's pure monster truck. The 4130 steel frame gives you the durability and stellar ride quality you've come to expect, while the R.O.S. 9's aggressive attitude comes from the short chainstays that make it a whippy beast in tight singletrack and the slack head tube angle that keeps everything under control at high speeds. A RockShox Revelation RCT3 fork gives you cushy landing gear when you huck, and the Stan's NoTubes ZTR Flow EX wheels make gnarly rocks and roots insignificant rattles. And with a SRAM X01 11-speed drivetrain providing the push, you get the perfect gear for ups, downs, and everything in between.
