If a cross-country bike met a trail bike out in the woods, they fell in love and had a child, what would that bike be? How about Niner's new AIR 9? The perfect blend of cross-country quickness mixed with a rowdier attitude. Run it geared. Run it single speed. 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.

Genetically engineered? Maybe not. But it sure is fun to ride.

The Niner AIR9 is a lightweight aluminum hardtail has always been capable. So how did they make capable even better? They kept the excellent qualities of their tried and true hydroformed aluminum - lightweight, snappy, poppy and peppy, the AIR 9 has plenty of stiffness to get you up to speed when you stomp on the pedals. Next, they applied their [R]evolution geometry which puts the rider in the sweet, balanced spot on the bike, elevating the ride experience. To top it off, they added Boost 148 spacing because stiffness and tire and wheel options are a good thing.  Add a dropper post with the AIR9's internal routing and you can make this capable whip go even bigger.
