Niner SIR9, size XL, frame only. Root Beer brown color--really nice metallic brown. There are numerous rock chips and scuffs on the frame, but no dents, and overall it's in good shape. Creak free, slip free, Biocentric EBB included. I've tried many different single speed mechanisms, and this is one of my favorites. It gives an easy, one bolt adjustment, with no fussing over wheel centering like with sliding dropouts. It also lets you play with bottom bracket height and chainstay length. For my 32x20 gearing, I have it set back and low, giving a true chainstay length of only 437mm. Includes a rear derailer hanger if you want to add gears later.
$325 OBO, shipping not included.
