I just got an 06 Bianchi Vigorelli. Most of the other bikes I was trying out were 54 cm. I tried Cannondale, Trek, Specialized and Felt in that size. The Lemond and Bianchi came in 53 and 55 cm sizes. The Lemond 55 felt too big, but the Bianchi 55 felt just right. I don't know if the Lemond ran a little larger or the Bianchi ran a little smaller, or a combination of the two.
