Niner's Air 9 Carbon is your private jet for all your cross-country trail travels. Feather-light with a stiff twist, the Air 9's carbon layup keeps vibration at bay so you feel like you're floating on cloud nine while pushing hard up the climbs or soaring down your favorite descents. A tapered head tube adds to the precision steering, while a Fox 32 Float CTD fork gives you 100mm of cush. A Shimano XT 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 XC wheels built for sailing over the rough stuff, and when it comes time to slow it down, rely on Shimano XT discs to haul it down. And, with Niner's carbon seatpost and handlebars rounding it all out, you get a light, tough rig ready for the long haul.
