I was planning on replacing the pulley wheels on the 90's Colnago Master Olympic with Campag Record I'm currently restoring, but I'm a little confused about which ones to get.
There is an easily available version called RD-RE500 that I bought that's supposed to be for 8-speed derailleurs, but the screws that go in the cage through the pulleys were too thick to fit them. My thought then was that maybe there's an upgraded version of the screws with a smaller diameter to fit these new pulleys, so I bought the screws called RD-RE106. These screws fit the wheels, but then I noticed that the new wheels are actually thicker than the original ones and wont turn properly when mounted.
This is the type of pulleys originally on the bike:
And these are the new ones:
Should I just give up and try to salvage the old pulley wheels or is there some other currently available version that is compatible with my derailleur?
