This is our latest  front derailleur, and the only Campagnolo thing we stock. It has a short cage for good clearance when your bike has an 80 drop and a 46T big ring. Whatever you have, it works wonderfully. The clamp fits 28.6mm seat tubes, which all of our bikes and most classic steel bikes have. It may be labeled "Champ", "Mirage" or "Centaur", and 9 speed or 10 speed. They're fungible, all work really well.

Your choice of triple or compact double.
