• Front derailleurs are pretty obliging, having a wide range of movement and not doing anything that is too sensitive.

    The difference in external width between 8v, 9v and 10v chains is minimal and wouldn't require the distance between the derailleur's plates to be reduced.

    Unlike rear derailleurs and Ergos, Campag don't mark the front "nine speed" etc, so it's reasonable to assume there's no need to differentiate between them.

    So yes, it should work.
