This bike was ridden by my wife, which means it was ridden very lightly. She keeps both wheels on the ground. I would estimate that it has 2-300 miles on it. There are some very light scratches on the seatstay. The bike has been VERY well taken care of, and was definitely a fair weather bike: no mud, no wet rides.
