Agreed, they do. Am I better off just going to the bike shop (do they do fittings for free, if not around how much would I expect to pay?). I understand each bike is different, but I'm better off getting a decent idea of what bike frame to get. From the other calculators I was told 56cm is my fit. :S

edit (for the trek i posted) - 1) How much should I look to expect to haggle down + how much could I get down if I'm lucky (desperate seller)
