Somebody needs to tell me how to quote your comments!

I knew that every bike manufacturer had different sizing, and confirmed that on my first day of test rides. My next LBS stop has Bianchi, which I want to try. The snooty pro-shop also has Bianchi, so I would like to look at Bianchi at the LBS before I venture into the elite shop so I maybe sound like I know what I'm talking about. If I think I like the Bianchi the best, I will get it at the pro-shop if their price is reasonable, just to get a more professional fit. I was also disappointed that the two shops I've been to so far didn't have very many bikes in the 58 cm range to try. Is that not a common size? Do most people ride something smaller than that?
