For model year 2008 the derailleur range was the same as it was in the 2007 catalogue. The range therefore was:
- Campagnolo Record (RD4-REXS)
- Campagnolo Record (RD4-REXM)
- Campagnolo Chorus (RD4-CHXS)
- Campagnolo Chorus (RD4-CHXM)

- Campagnolo Veloce (RD7-VLXS)
- Campagnolo Veloce (RD7-VLXM)
- Campagnolo Veloce Infinite (RD7-VLNXS)
- Campagnolo Veloce Infinite (RD7-VLNXM)
- Campagnolo Mirage (RD7-MIXS)
- Campagnolo Mirage (RD7-MIXM)
- Campagnolo Xenon (RD7-XEXS)
- Campagnolo Xenon (RD7-XEXM)
- Campagnolo Comp Triple (RD7-COXL)
- Campagnolo Race Triple (RD7-RAXL)
- Campagnolo Champ Triple (RD7-CP9L)
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.
