NOTE* This is a return. This frame has minimal wear from shipping and is in excellent condition.

The Air 9 is a super light geared-only (i.e. not single speed compatible) frame utilizing custom drawn Easton GX2 Scandium. Combining a truly advanced proprietary alloy with higher strength properties than 7005 series aluminum with the rare earth element of scandium, Easton achieved the impossible: a super lightweight tube with a compliant ride characteristic. Blending Easton’s tubing with custom drawn and shaped rear s-bend chain stays and seat stays, the Air 9 is a light, agile ripper of a frame that offers a surprising amount of comfort to the long haul.

Niner worked directly with Easton engineers to dial in the Air 9’s tube set, including the custom bent Niner down tube, which strengthens the head tube/down tube junction while simultaneously increasing fork crown clearance. Chain stays and seat stays have maximum tire clearance and heel clearance, and the top tube is radically sloped to allow for better stand-over height.

Whether you’re a racer or a fan of lightweight, high-tech bikes, the Air 9 delivers the goods in a stunning, wicked fast masterpiece that combines the best Easton tubing with Niner’s proven geometry and gives it to you with the hope that you will set it free.
