Overview
About this bike
Niner's new AIR 9 is the perfect blend of cross-country quickness mixed with a rowdy attitude. Run it geared. Run it singlespeed. Comfortable enough for all-day riding and quick enough to pin it at the races, the new AIR 9 handles what you throw at it. Modern geometry puts the rider in the balanced spot on the bike and Boost spacing gives you tire and wheel options to suit your style and location. Top it off with internal routing for a dropper post and you're looking at one very capable bike. The 1-star build gives you a SRAM NX 1x11 drivetrain, Level hydraulic disc brakes, and a RockShox Judy Gold fork with 120mm of travel. 29-inch Niner alloy wheels wrapped in Maxxis Ardent rubber supply the perfect mix of traction and speed for hot pursuits, and the Race Face Aeffect R bar and stem combo complement the AIR 9's geometry for precise control when you want it most.
