Thank you for the replies and useful information and insight. I hadn't considered the possibly the bike could be stolen. Since the seller was in law enforcement I think he is legit. obed 7 you mentioned taking it to the Trek dealer for servicing. There is a Trek dealer in my town that is a large chain sports retailer. I have always used the local bike shop that sells Specialized and Giant. I prefer to use them since they are local, family business and the money is more likely to stay in town. Is my thinking flawed that they could service the bike as well as a Trek authorized mechanic?
