Elevate your riding
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 singlespeed. 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.
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 peepy, the AIR 9 has plenty of stiffness to get you up to speed when you stomp on the pedals. Next, apply our [R]evolution geometry which puts the rider in the sweet, balanced spot 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.
- Boost 148 spacing allows for tire/wheel options and more clearance.
- A proper tapered head tube allows riders to keep up with front fork technology.
- Internal dropper post routing.
- [R]evolution geometry makes for better handling.
- Forged chainstay/bottom bracket junction allows for better stiffness and tire clearance
You're looking for a capable bike. You just found one. Modern geometry and amenities make this bike hard to pass up. And sure, you can say what you will about other aluminum hardtails, just don't say it about this one.
