This bike was basically given to me along with another bike that I purchased from a friend. It's a Dawes Lightning Sport and I don't know too much about it, but it looks to be about 54 - 56 cm and everything seems to be in pretty good shape. It also has a cateye computer on it. I have no use for it, but it could turn into a neat little commuter. First 50 bucks takes it or 25 and a 12 pack of good beer...lol.
