This is a Giant OCR3 size "Large" (57 cm--advertised to fit people 5-11 to 6-3). I bought the bike new in 2007 for $650. The OCR3 is an entry level road bike with an aluminum frame, carbon fork and Shimano Sora components. Many parts of the bike have been replaced in recent years: both wheels, bottom bracket, drive train and cables have been replaced, and I've taken care of maintenance items like changing the bar tape and adjusting the shifters. The frame has some scratches. Brand new Thick Slick front tire. It's a fun light bike for commuting and a good way to explore the roads. More pictures available on request.
