•Niner Bikes’ lethal Air 9 hammer, Mountain Bike Action (November 2006)
•
“The Air 9 is the best handling hardtail 29er we’ve ever ridden; The Air 9 we tested is ready to win a cross-country race or to rule local singletrack”
Niner's all new Air 9 exemplifies high performance at O2 weights with the custom butted and drawn Easton Scandium GX2 geared only frame.
While the Air 9 is based on Niner's award winning One 9, we didn't just simply put a derailleur hanger and a standard bottom bracket into the One 9. We redesigned the frame from the ground up with an all new proprietary Easton GX2 tubeset. Everything from the drop outs to the head tube was re-examined for maximum weight savings while still maintaining the strength and ride quality that is paramount to all Niner frames.
The ever critical head tube junction is one of the most important sections on any frame, especially 29" frames. The larger lever arm (longer fork and taller wheel) combined with the shorter head tube increases forces on this critical area substantially, and while all Niner frames pass stringent testing standards, we wanted to improve this junction while decreasing the weight. Niner and Easton worked side by side to come up with a proprietary downtube designed to be used without a head tube gusset while still maintaining the necessary clearance for fork crowns. The bent downtube was the best solution and simultaneously increased the strength of the head tube area while decreasing the weight and created the clearance needed to fit any fork on the market on this frame.
In the rear triangle, we've also redesigned the s-bend chainstays and seatstays for increased heel and mud clearance while maintaining the vertical compliance and lateral stiffness of the stays. The drop outs are "Breezer" style drop outs with a replaceable derailleur hanger. All the details you've come to expect from Niner are, of course, standard here which include an internally butted head tube and BB shell, faced head tube and BB, reamed seat tube, a faced disc tab and chased BB threads for a frame that's ready to build right out of the box.
Niner ups the anti yet again with the Air 9: a super light frame with the smooth rolling, compliant ride of Easton Scandium, this time, for riders who prefer gears.
