This carbon road bike is in great shape. Measured at 53 cm center to center top tube and a deceptive seat tube length at 51 cm center to center (virtual). The top tube curve yields a physical measure of closer to 46cm but the bike as set up currently would fit riders up to about 6 feet (it is comfortable for me at 6' 1"). Shimano 105 gruppo. Price is firm at $600. The bike can be viewed at 244 Brittania Rd Wednesday from 5-8PM or Saturday from 12-5 PM From the company: Specialized's Roubaix Comp is a zippy road machine that rides so easily and comfortably that you can easily double your miles. Specialized's Zertz vibration-damping elastomer inserts boost the carbon fiber's inherent road-smoothing qualities, and the upright riding position delivers a custom fit and brilliant handling while being significantly easier on your neck and back. Plus, the 20-speed Shimano 105 drivetrain delivers the right gearing for every ride while the reliable Shimano wheelset rolls effortlessly and is built to last.
