Excellent condition; 2013 Niner Sir 9 Frame. The frame is steel and has Reynolds 853 tubes. The headtube is 44mm so that you can run a tapered fork or straight steerer type. Frame includes headset, EBB version 2, and both a SS and Geared der. hanger. Rear hub spacing is 142x12mm. Frame also comes with Rockshox Maxle rear thru axle. Frame size is a Large. I am looking to get $775 plus shipping for this barely used frame.
