The derailleur range changed a lot for model year 2007. All the groupsets from Centaur down were new 10 speed models. The long cage derailleurs were not included in the usual named groupsets, but were separated out with their own model names. The only remaining 9 speed derailleur was the Champ Triple.
The range now was:
10-speed
- Campagnolo Record (RD4-REXS)
- Campagnolo Record (RD4-REXM)
- Campagnolo Chorus (RD4-CHXS)

* New for model year 2007
From 2004 onwards the part numbers were made up as follows:
- 'RD' for 'rear derailleur'.
- Numbers to indicate the year of introduction. So, for example, '4' indicated 2004.
- A dash for good measure
- Two letters that indicated the model/group name. So, for example, 'RE' meant Record.
- Some, slightly random, optional, letters that indicated colour options. So, for example, 'G' meant Century Grey.
- A character to indicate the number of speeds. So '9' for 9-speed and 'X' for 10-speed.
- A letter to indicate cage length. So 'S' for short, 'M' for medium and 'L' for long - all of which was curiously not in Italian.
