For model year 1993 Campagnolo made the following changes to their range:
- Record, Chorus and Athena got a makeover.
- Veloce was introduced as a new low-end road group.
- Record OR and Icarus got a makeover.
- Centaur also got a makeover, but the short cage Centaur was discontinued. Centaur appeared to have an aluminium outer pulley cage plate.
So I think that the rear derailleur range might have gone as follows:
- Campagnolo Record (RD-11RE)*
- Campagnolo Chorus (RD-11CH)*
- Campagnolo Athena (RD-11AT)*
- Campagnolo Veloce (RD-01VL)*
Mountain bike 8-speed
- Campagnolo Record OR (RD-11OR)*
- Campagnolo Record OR (RD-12OR)*
- Campagnolo Record OR (RD-13OR)*
- Campagnolo Icarus (RD-11IC)*
- Campagnolo Icarus (RD-12IC)*
- Campagnolo Icarus (RD-13IC)*
- Campagnolo Centaur (RD-12CE)*
- Campagnolo Centaur (RD-13CE)*
*New models first appearing in this catalogue
From some time around 1992 the part numbers were made up as follows:
- 'RD' for 'rear derailleur' - which was not particularly Italian.
- A dash for good measure
- A number to indicate the 'generation' of the model. So, for example, generation '2' replaced generation '1', etc...
- A number to indicate the cage length. So '1' indicated short, '2' indicated medium and '3' indicated long. etc...
- Two letters that indicated the model/group name. So, for example, 'RE' meant Record.
In this catalogue the rear derailleurs are featured from page 26 to page 32.
