Campagnolo Centaur 11 Speed rear derailleur, comes with many technologies from Campagnolo's top rear derailleurs. The Cantaur switch has a medium arm which makes it possible to have a cassette of up to 32T on the cassette.

The rear derailleur has pulley wheels at the top with large long teeth and small smoother wheels at the bottom to guide the chain well through and further around the cassette.
