holy cow. a LBS sells a used bike, as new, to someone who comes in for their first road bike? that's borderline criminal. when you take it back for a refund, make sure you mention how you didn't identify their shop on this forum, so as not to embarrass them. but you would, if they don't take it back and give you a new bike. but only go there if they are uncooperative. if you charged it, just leave the bike there and dispute the charge with Visa or Master Card. as an aside, you should be able to get a carbon bike for not too much more than that aluminum model, maybe with a little more newbie-friendly geometry.
