FWIW the frames you mention all have the same BB
thread and shell. Italian frames are the major outliers
and many of these are sold with English threading as
are all frames sourced in the US and from the far East
that are shipped to the US. There will be outliers and
oddities, but this generalization is valid especially at the
low and midrange frame level for frames made in the last 10yrs or so. If using an older frame then outliers are more likely if the frame is European in origin. Campy square taper is slightly different from the other European square taper BB but usually not enough to be a problem. If you stick to East Asian BB then this will not be a problem. Steve
