    Cross check sizing?

    How do you determine the proper size for a cross check? Going to a shop isn't a possibility.


    (I only found one other thread on this issue and that was for some guy's wife)

    Should the book stop at the balls, or should it go all the way to the area on which the balls are connected?

    And I'm guessing if I "need" a 51cm according to the site then I should go down to a 50cm? And if the measurement is like 30.25 inches then I should input 30 inches?

    The book should be pushed firmly into the crotch, attempting to apply nearly the same pressure that sitting on a bike saddle would apply.

    I tried a trek 1.1 with a 52cm frame and found it better than the 54cm frame. I'm too stretched out on the 54cm, but just by a smidgen.

    I tried a cannondale synapse and the 51cm felt great. a caad 10 in 54cm felt too long.


    So, what say you?

    To me it looks like the 50cm is the right choice. There's only .2 inches difference between it and the 52cm, so I could just get a longer stem if I found later that it was too short I think.


    Here are some geometry charts.

    The top tube length is more important for fit than the standover height.

    Tob tube length

    cannondale - 52.5cm
    trek - 53.4cm
    surly cc - 53.5cm

    The 52 trek looks very close to a 50 cross check

    Also, would you buy a 52 from a shop you trust or a 50 from one you don't (because the other one doesn't have a 50)?
