I need to replace my old Campy Chorus 7-speed RD because of a crack in the inner eye hole of the pivot bolt. I'm thinking about buying the new '04 10-speed carbon Chorus RD but I'm not sure if it will be compatable with my existing drive train. I don't want to buy a whole new groupo if I don't have to. I have had these components for years and they still work great.
Here is what I currently have for the drive train:
RD - Chorus 7-Speed
FD - SuperRecord
Shifters - Synchro2
Cassette - Chorus 7-Speed (11 x 23)
Chain - Regina (I think?)
Crank & Chainring - Chorus (53 x 42)
Any help would be great.
