I need to replace my FSA Orbit CE Plus headset on my 2008 Bianchi 928 Carbon.

The headsets come in two sizes for 46mm and 50mm O/D Headtube.

Can someone tell me which I need? And whether or not I need an 8mm or 15mm stack height?

    Measure your frame?

    The stack height refers to height of the top race cover i.e the bit that fits on top of the bearing and undernesth the stem.
    Make mine an Italian, with Campagnolo on the side..

    Ah.

    Can't believe it was that obvious. Feel a bit foolish now.

    Measures up for a 46mm.

    Thanks for the advice.
