Everything on the bike is in race-ready condition and functions perfectly. No mechanical issues. This bike has been ridden in several races, so it comes with some history, which is part of why this is a bittersweet sale for me. The next owner will be getting a bike that's proven itself on race day, not just in a showroom.
