Okay...I'm a roadie, but new to the fixed gear/single speed world. My local bike shop has a used Surly Steamroller for $300. It comes with a flip-flop hub which I will have them put a free wheel on the other side, and a front brake. I think everything else is stock. The bike looks to be in great shape. I guess the guy bought it, rode it a few times and then stored it. Is this a good deal, and is there anything I should be looking for that a road cyclist wouldn't know to look for?
