I think you guys live in a different bike "world" than I do. I'm in NC and the shops don't carry all sizes of all models. I know there's more than one shop, but I travel the state a lot with my work so I can visit shops in all the major cities. If wanting a Madone in size 52, I would not be shocked if one doesn't exist as a stock bike available for test ride in the state. I wanted to try out a F8 and again, but again I'm pretty sure there aren't any around.
