    10 Sp. rear derailleur w/9 sp system

    Can I use a 10 sp Campy rear derailleur with a 9 sp Campy system just by changing the pulleys to 9 sp? thanks!

    It'll work just fine...

    ...without changing the pulley's.

    On a sub-atomic level, a pulley swap will improve shifting just enuf that a scanning electronic microscope might see a difference...

    yes, but...

    The shifting will not be perfect, not because of the pulleys, but due to a change that Campy made to the RD's parallelogram.
