Bike is fully functional, but does have some signs of wear and tear. Some finish blemishes, marks, and scuffs - including a spot where the decal on the top tube appears to have started peeling, and a bubble. Shifters show some marks. I've tried to picture all cosmetic damage, please check out the photos. The rear hub could stand to be torn down and greased. As far as I can tell most of the bike is original, except for the saddle (I believe it is a Butterfly Ti saddle), the front derailleur (original Ultegra was replaced with what appears to be a Microshift front derailleur, before I owned the bike), and the rear wheel, which is an Alex Rims wheel, rather than the original Bontrager. New bar tape.
