Niner's Air 9 Carbon is a smooth, cross-country bike that gets you there fast. Feather-light with plenty of stiffness, the Air 9's carbon layup keeps vibration at bay so you feel fresh while pushing hard up the climbs or soaring down your favorite descents. A tapered head tube adds precision steering, while a RockShox Recon Gold fork gives you 100mm of cush. A Shimano Deore drivetrain gets you up to speed with 2x10 gearing and quick, responsive shifting. Take this XC flyer to the dirt and roll smoothly thanks to 29-inch Niner wheels built for conquering straights and twisties, and when it comes time to slow down, rely on Shimano discs. And, with Niner's aluminum seatpost, stem, and handlebars rounding it all out, you get a light, tough rig ready for the long haul.
