    help with a9 ss 32/18 gearing

    so I have an old 08 or so air9 running 32/18 ss without a tensioner . works out perfect using a 1/8 chain with half link . does anyone know if the 2012 design with pf30 has the same chainstay length? I would be using xo cranks with pf30 adapter. the new air 9 is on sale for $350 cheaper than the one9. thanks!

    Niner has full geometry listed on their site.

    AIR 9

    Click on the "Sizes and Geometry" tab

    You could measure yours and compare or you could contact Niner directly. They are very helpful.
