Hi all, I have measured the following Campagnolo pullies with their hardware attached, and the measurments are as below. the old dark grey ones suffer from old age cracks, if caught in time can be super glued for use, but mainly not caught in time and need thrown out. I've found some that suffer from a lot of sideplay, this can be remided by sanding the pully sidefaces smooth on a flat sheet of 600 grit wet & dry sandpaper and shortening the centrebush so that when assembled with sideplates will only have .010" or .25mm sideplay, this will improve shifting, if shifting is not the best. The C records ones are nice, but 2 things are required if using in an older RD, the proper adjusting spanner, really makes that job easy, and secondly some shim washers to get back to the 10.50mm spacing. Can't see the need for fitting old pullies to a modern OT RD, could be done if you really wanted.....regards wayne davidson Invers NZ......
