Which has the larger diameter? I have a pair of Ultratorque cups that are 1.370"x24 TPI, are they English or Italian? Are Colnago BBs around 2009 English or Italian? Thanks

    In terms of your Colnago, what model of frame? - only some Italian-built ones use ITA BBs, the latest use BSA. All the Giant-built Taiwanese model are BSA. Italian thread is 36mm x 24TPI RH on both sides which is a 'bastard' size if ever there was one.
    Make mine an Italian, with Campagnolo on the side..

    We don't do inches in Italy, so you've got your answer... :wink:
