Niner Air 9 Carbon

As its second foray into carbon fiber, Niner is launching its Air 9 carbon bike this spring. The Air 9 Carbon is a 2.8-pound (for a medium) 29er (29-inch-wheeled bike) with completely original components.

The company claims it’s the only carbon 29er in the world that can be run as either a single-speed or geared bike – there are non-carbon frames currently on the market that can as well. For added strength, the hardtail, designed for downhill, freeride and all-mountain use, incorporates alloy at key junctions like around the bottom bracket and head tube.

It has a hexagonal downtube made for strength and stiffness and the bottom bracket shell accepts CYA inserts for BB-30 and X-Type bottom brackets as well as fits Niner’s BioCentric bracket. The shifter cables are routed through the bike’s frame for a clean look.

The Air 9 Carbon frame, which comes in white or yellow-orange, will be available in April for $1,899.

maybe the only carbon bike that can be run single speed and geared?

I’m pretty sure you could get a redline monocog flight 29er with a derailleur hanger, same with lynskey.

Guys, you’re exactly right.

I double checked with the company and they say it's the only carbon 29er that lets riders run it as a single speed or geared. I just edited the post.

I want that. I’m not usually a carbon guy, but this thing is beautiful.

I’m with TC, this thing is sweet. And looking at the picture, I notice it is so light that the back end floats, whoa.

That thing is, categorically, a succulent morsel of buttery goodness. Do I hang it on the wall or ride it? Yeah Stanley, I see what you are talking about. That thing’s rear end must be so light—I want that.

“designed for downhill, freeride and all-mountain use”

I’m not sure this is quite correct. This seems to be a cross country machine to me.

Brandon is right on. Cross-country race for the most part. A few ss geeks will run it on endurance rides (maybe this will end up being me if I get one…). It is definitely a thing of beauty, and not like the uppity Gary Fisher Superfly which you can’t get singlespeed unless you know someone

maybe the only carbon bike that can be run single speed and geared? Yes. Redline and Lynskeys don’t make carbon bikes, they are Steel, Aluminum or Ti. Lynskeys are nice too!

how does it compare to the S Works HT Carbon Stumpjumper 29er?? Both very light but Specialized comes with a front suspension. Wheelbases both similar I notice and closer to a 26 bike for good handling.
