Aluminum single speed disc brake 26" wheel bicycle frame only, no fork is included with this sale, works with a 1 1/8" straight steerer fork. I had both a Rockshox short travel and a rigid on this frame and handling was good for me both ways. I'm not sure what the original bike was equipped with, but this would probably also work well with the Surly suspension corrected fork (100mm I believe). Designed by Sky Yaeger of Bianchi. This frame shows a lot of wear to the finish, hard to overstate how many little paint chips, looks like it has the measles, but the damage has been confined to the paint. Very light and rides great, but I need more than one gear around here these days. Will include one wheel tensioner for the right side dropout. If I can track down the disc brake caliper (Avid BB&? not sure) I will include it, but no promises. Thanks and if you have any questions, please ask before purchasing. Rear spacing is 135 O.L.D.
