Niner Air 9 Frame 2012

The Air 9 is Niners fast, light, geared-only alloy racing hardtail. This upgraded version integrates hydroformed tubing throughout. More than a cosmetic feature, hydroforming allows Niner to shape tubes and optimize strength and stiffness in key areas, giving the ability to create beautifully tuned frames with precise ride characteristics. You will find hydroforming in the toptube, downtube, headtube, chainstays and seatstays.

Because of the larger welding area created by the new tapered headtube, we are able to include a massive hydroformed downtube as well as a significantly larger diameter toptube, contributing to a much stronger frame. Chainstays, seat tube and seatstays also benefit from hydroforming via controlled wall thicknesses and enhanced butting profiles. This translates to a rear triangle that is tuned for stiffness, strength and vertical compliance – in other words, ideal ride feel.

The Air 9 features a tapered headtube with an integrated headset. By allowing for the use of the newest generation of 1.5” tapered steerer suspension forks and integrated headset, Niner create the stiffest front end possible – leading to amazing steering precision as you carve a corner and descend toward the finish line, with the same stack height as their original Air 9 model.

Additionally, the updated Air 9 now features anodizing friendly tubing, allowing folks to get a rugged and extra-light finish in a stealthy black with low profile logos.

Bottom line? A lighter, stiffer frame with better ride feel and improved steering results in better power transfer and an overall efficiency improvement. In other words, the updated Air 9 will win more races.

      Sweet frame! Responsive and light. Zooms up hills. Put a rigid carbon fork on and bike is under 20 lbs. Very nice

        Comments about Niner AIR 9 Frame 2012:

        I bought this frame to build up a good solid bike I could ride for many years. I'm pretty new to mountain biking as I've spent most of my time in the saddle on the road. I rode this frame at Outerbike in Moab and absolutely loved it. I'm 5'8" and I could have gone with either a med or sm. After riding both sizes in Moab, I chose the sm frame as it just seeemed to be more responsive and did everything I wanted it to. I built it up with mainly Shimano XT parts. Nothing bad to say. Also Jenson had a smoken deal on this frame and I couldn't pass it up. I only gave this a four star rating as 5 would be perfect with no room for improvement. And nothing is perfect.
