I bought this bike last fall on a trip out west and have come to the realization that it is too much bike for where I live (michigan). When I got home, I stripped the frame and powder coated it matte black (it was a reddish / orange from Giant). I replaced the entire back end of the bike, this includes the rear triangle, all the bearings, the links, and suspension axles. The frame is in perfect shape & is basically new. There are 2 spare sets of rear dropouts (1 at 442mm & 1 at 445mm in length). Both are anodized blue. The rear hub is included and is a Jumping Flea from Sun Ringle. The rear shock is a Fox DHX 5.0 with a 500 pound coil. To fill in some pertinent details the frame is something like a 66 degree headtube, 23.25" top tube, tapered steerer, 150mm rear end, 83mm bottom bracket, 30.9mm seat tube, & 7 inches of travel. It will fit 26 size tires.
