Centaur rear derailleur.
The rear derailleur is the defining component of the Centaur groupset. Many technologies have been adopted from Campagnolo's top-of-the-range rear derailleurs, so Centaur offers a shifting performance capable of meeting all requirements, even those of the professional cyclist.
The new Campagnolo Centaur rear derailleur has been designed to be compatible with cassettes up to 32 teeth, with the upper derailleur pully having longer teeth, the lower with rounded teeth.
With it's long list of performance-oriented technologies, the Centaur rear derailleur is at the top of its class, weighing 230g, a total of 15 grams less than its competitors.
