    I was looking at some campy record cranksets on the bay. found some 10 speed
    cranksets from 2003 which were said to have EXA chainrings. And a 2004 model
    which was said to have Ultra drive chainrings?

    any difference? Are they interchangeable? Ramps different btwn them? Do all
    10 speed chains work on both EXA and UD chainrings?

    thanks,

    Mike

    'Ultra drive' is the additon of smaller ramps inside the bigger ramps of the
    cogs. Mostly marketing and all Campagnolo stuff, from pre EXA to present UD are
    intercompatible.
