2013 Niner AIR 9
The Air 9 is Niner's lightweight, geared-only alloy racing hardtail that is remarkably fast! The new frame integrates hydroformed tubing throughout. More than a cosmetic feature, hydroforming allows Niner to shape tubes and optimize strength and stiffness in key areas, giving them 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, Niner was 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.
Bottom line? A lighter, stiffer frame with better ride feel and improved steering results in better power transfer and an overall efficiency improvement.
