Because the racing bug doesn’t choose who it bites, Niner offers the AIR 9. With World Cup-tested mountain bike race geometry and lightweight hydroformed aluminum, this privateer-priced bike has the design to win. Hydroforming allows Niner to control the shape of the tubes and wall thickness to optimize strength and stiffness in key areas. The rigid sides of their signature down tube and top tube shapes maximize torsional stiffness, with a buttery smooth ride quality achieved via the flat sections on each tube, which act like leaf springs. A PressFit 30 bottom bracket and 142 x 12mm thru-axle complement and magnify this efficiency, ensuring lightweight stiffness where power might otherwise be lost to frame flex.
The AIR 9 2-Star demands respect, not a second mortgage. The RockShox Reba RL Solo AIR fork keeps the entire bike lightweight, while quietly delivering 120mm of speed-carrying travel, so you can focus on going faster and hitting your line, not holding on for dear life. The streamlined SRAM 1 x 11-speed GX1 drivetrain delivers a wide range of gears without weighing you down or cluttering your handlebar with a left shifter. And, SRAM DB5 hydraulic disc brakes team up with Maxxis’ incredible Ikon tires to ensure you reign-in that well-geared speed when you need to carve a tight line. The AIR 9 2-Star is your launchpad into cross-country dominance.
