With Shimano it is easy to find compatbile parts in a groupset because they will all share a model number system.
For example, Shimano 5800 series will consist of:
- FD-5801 Front Derailleur
- FC-5800 Crankset
- RD-5800 Rear Derailleur
Does Campagnolo have a similar system?
It can be quite confusing since names such as "Chorus" are recycled between years; "Chorus 10 speed" is not enough to indentify a groupset.
