Modern aluminum racer for "Trail Country" adventures.
The Niner AIR 9 Hardtail 29" in silver/blue (2023 model) combines the efficiency of an XC bike with the capability of a trail hardtail. With its balanced geometry, the Fox Float 32 Rythm suspension fork, and a complete SRAM 12-speed Eagle drivetrain, this bike is ready for fast marathon laps, more technical trails, and long days in the saddle.
The elaborately hydroformed 6061-T6 aluminum frame offers an excellent balance of stiffness, weight, and comfort. Niner's "Trail Country" geometry, with a steep seat angle for climbing efficiency and a slacker head angle for stability on descents, puts you in a centrally positioned, controlled riding stance - perfect for challenging terrain and modern trail profiles.
The suspension is controlled by a Fox 32 Rythm 29" suspension fork with 100 mm of travel (GRIP damper, 44 mm offset, Boost 15x110 mm). Combined with the Niner 29" wheels (30 mm internal width) and Schwalbe Racing Ray / Racing Ralph Super Ground TLE Evo tires, this delivers a fast yet versatile setup for cross-country, marathon, and more aggressive rides.
Power comes from a SRAM Eagle 1x12 drivetrain with SX Eagle Rear Derailleurs & Trigger, SRAM PG-1210 11–50T cassette, and SRAM X1 1K Eagle DUB crankset with a 32-tooth chainring. The wide gear range gives you plenty of reserve for steep climbs without sacrificing top speed on the flats.
Braking is handled by a SRAM Level disc brake and G2CS brake rotors (180/160 mm). The Race Face Aeffect R handlebar (780 mm, 20 mm rise, 35 mm clamp) and the short 40 mm stem provide a direct, trail-ready cockpit. A Niner saddle, Niner seatpost, and Niner Grrrips round out the package perfectly.
Tubeless setup note: The wheels are already tubeless-ready (tubeless installation without an inner tube, sealant is included but has not yet been added). The bike is delivered without air in the system - add sealant, inflate, and ride.
