Niner Air 9 Carbon 3-Star XT Bike



For every model, whether it's their lightest cross country hardtail or the burliest full suspension bike, Niner considers how each angle or length will interact with big wheels to affect the finished build.

Rather than just offering the same carbon products, Niner makes sure they are maximizing the benefits of the material so that their carbon products are purpose-built from the ground up.

The basic concept of the larger diameter is simple: it will keep your wheels on top of oncoming obstacles. Rather than riding IN the terrain, you'll be riding ABOVE it, gaining more control and stability on even the roughest trails.

Niner Air 9 Carbon 3-Star XT Bike

Lighter than air? That's what you might think, once you try out the Air 9. With years of research and development put into the Air 9 series, these machines are race-ready cross country hardtails designed for maximum speed. Featuring the same, sleek frame design as the high-end RDO model, the Air 9 Carbon uses a simpler layup resulting in a slight (albeit negligible) increase in weight. Rigid and fast, the Air 9 Carbon provides excellent acceleration and power transfer through its refined frame geometry. A favorite among hardcore XC racers, the Air 9 Carbon was even used to win the Singlespeed World Championships. If you are in search of a bone fide cross country machine, the Air 9 Carbon should already be on your radar. This particular version, the 3-star build, offers high-level components like Shimano's XT M8000 drivetrain, a RockShox Reba RL fork, and XT M8000 Series disc brakes.
