This bike is a well maintained road bike. It has no mechanical issues to the point that its ride ready right now. It has been sitting in my garage for almost a year so tires are about half life right now. They are still holding air cause i rode it to the store last week. Its a 25 inch frame on 20 inch tires with a kevlar rear tire and a michilan A2 front tire. Still has the Shimano crank and pedals original with bike as well as the Shimano SIS light action gear changing system that still works well. If interested please cal
