Bought a used 2011 Trek Madone 5.2 on CL. The original owner said he hadn't ridden it much prior to having health concerns and can't ride now. To my untrained eye the bike looks to be very low mileage/use. I am quite anxious to ride it but am wondering what maintenance/inspection things should I do before taking it out. Can I ride it without damaging anything prior to taking it to my LBS? Should I tell them the "story" so they can look for specific things?
