We had a shop here that had a bunch of cheap steel road bikes with nice components (Ultegra mostly), the components were slightly used looking at a close look. Thieves steal good bikes, take the bikes apart and sell this a$$hole the parts to go on his "new" bikes. The stolen frames were thrown away, impossible to track the components. This guy left town after people were on to him, I hope that he's not operating in your town now.
