Trail Blazin'

Why We Love It
The Niner Air 9 RDO is a lightweight trail rocket. This hardtail's primary focus is on maximizing your power to the pedals and propelling you quickly down the single track. However, contrary to many cross country hardtails, Niner wisely incorporated a few trail focused strands of DNA in its geometry to give you the upper hand when the terrain turns choppy, leaving your competition in the dust.
Master Mechanic’s Notes
  • New bottom bracket
  • Light scratches on the bar ends
  • Light scuff on the rear derailleur & crank arms
  • Small paint chip on the drive-side top tube
