For model year 1995:
- Every derailleur except Record OR was restyled.
- Stratos was replaced by Mirage and Avanti. Stratos only lasted for one model year.
- Long cage models were added in Athena (called Racing Triple), Veloce and Mirage.
- Record OR was only available in the mid-cage-length. It's possible that both the long-cage and short-cage versions had sold out and Campagnolo did not want to manufacture any more.
I think that the derailleur range was:
- Campagnolo Record (RD-31RE)*
- Campagnolo Chorus (RD-31CH)*
- Campagnolo Athena (RD-31AT)*
- Campagnolo Racing Triple (RD-01RA3)*
- Campagnolo Veloce (RD-21VL)*
- Campagnolo Veloce Triple (RD-03VL)*
- Campagnolo Mirage (RD-01MI)*
- Campagnolo Mirage Triple (RD-03MI)*
- Campagnolo Avanti (RD-01AV)*
Mountain bike 8-speed
- Campagnolo Record OR (RD-22OR)
* New for model year 1995
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.
From 1995 this plan was disturbed by the Racing Triple, which had a cage length digit of '1', and then a '3' at the end. Weird or what?
These images come from a slightly tacky pdf downloaded from the Campagnolo web site some years ago. The rear derailleurs are featured from page 18 to page 25.
