    Bianchi Cross Concept sizing?

    I'm 5'7" and am looking to get a Cross Concept. It seems like there is a big jump from 49cm frame to 52. Riding a 51cm Jamis Supernova and it fits great, but have had a 52cm Cannondale that fit way too big and caused some back pain. Anyone have experience with these frames? Do they run big?

    if the supernova fits great, why are you looking to replace it?

    were you too stretched out on the cannondale?

    the geometries of the 51 supernova and the 52 cross concept are essentially identical. they both have 53cm effective toptube lengths. the jamis does has a 5mm longer headtube though, which is insignificant. in my opinion, toptube and headtube lengths are the most important dimensions for fit. they both seem to have the same bb height as well... however, bb height has no affect on fit while riding, only when standing over it.
