This super nice, gently ridden, 51.5 cm carbon frame bike has been ridden twice over the past 5 years. It is in great condition with new tires and 105 components throughout. The frame is meant for a person 5 ft to 5'7". No crashes on the frame. We bought this cyclocross bike so that my wife would have the option to ride on gravel trails . It was not used for off road at all.
