Niner Air 9 Frame
This item is currently not available.


Let's face it. The AIR 9, Niner's lightweight aluminum hardtail, has always been capable. So how do you make capable even better? For one thing, you keep the excellent qualities of Niner's tried and true, hydroformed aluminum. Lightweight and snappy, poppy and peppy, the AIR 9 has plenty of stiffness to get you up to speed when you stomp on the pedals. Next, apply their [R]evolution geometry which puts the rider in a balanced position on the bike, and the ride experience goes up, way up. Then, add Boost 148 spacing because tire and wheel options are a good thing. Top it off with internal routing for a dropper post and you've made one capable bike even more capable.

Niner's AIR 9 is the perfect blend of cross country quickness mixed with a rowdier attitude. Run it geared, with 1x or 2x compatibility. Or, run it singlespeed, using Niner's Biocentric BB. It's comfortable enough for all-day riding and quick enough to pin it at the races. It's got a tapered headtube for front-end stiffness and accepts up to a 120mm fork. With room for tires up to 29 x 2.4" or 27.5 x 3.0", the AIR 9 handles anything you throw at it.
