The Niner Air 9 2-Star Hard Tail Bike is a lightweight aluminum hardtail, that is a very capable trail bike for the up and down.  The frame is crafted of tried and true hydroformed aluminum, that is both lightweight, snappy peppy and poppy. It’s a stiff frame that really gets you up to speed fast when you stomp on the pedals.   With Revolution geometry, you are always in a balanced spot along with Boost 148 spacing for a wide variety of wheel and tore options to run.  A dropper post makes the bike even more trial worthy. The Niner Air 9 2-Star Hard Tail Bike is comfortable enough for all day riding but quick enough to suit up at your local cross-country race too.  Whatever you throw it, this bike is ready roll! Tis Niner Air 9 comes with a 2-star build.
