Are these meant to fit a 46mm or 48mm OD head tube?

Thanks.

    it depends on the frame.

    there are versions for both steerer tube sizes. measure the bearing size.

    Bearings are 41.9mm OD so designed for headtube ID of 42mm - headtube external diameter is fairly arbitary as it can also depends on the thickness of material:

    Make mine an Italian, with Campagnolo on the side..

    Well, that was my thinking as well. However, 'Campag fit' 45x45 11/8 integrated headsets are mostly suited to head tubes with an OD of 46mm - the OD is not insignificant, as it were.

    I've just ordered an FSA Orbit CF 42/48, which, as the name implies, is for an ID of 42mm and an OD of 48mm. This is, by the way, a tapered headest, with 1.5" at the bottom.

    I'm having to buy this from Italy because it is not available in the UK.
