In the same way as the front derailleur, the rear one also exploits many developments achieved for its mechanical 12-gear predecessor. The same 45° trajectory angle corresponds to a new change of position that electronically improves chain engagement specific for each sprocket. Better power transmission and less wear and tear of consumer transmission components are just two of the advantages of the positioning of this new rear derailleur with respect to the cassette. Compatible with the two 11-29 and 11-32 cassettes, the two pulley wheels have 12-tooth design and the 72.5 mm derailleur cage ensures perfect performance. The slimmer, sturdier structure of the resistant derailleur cage gives more space between the derailleur and the spokes, making it easier to adjust. Moving the chain onto 12 sprockets in the cassette calls for greater precision, given the increased number of chainrings in the same space. The firmware not only manages this task efficiently and quickly, but the front and rear actuators do their job using the most powerful motors available on the market. Built with materials such as aluminum, ultra-lite technopolymer and long-fiber carbon, the EPS rear derailleur has been built to meet Campagnolo standards in terms of extreme durability, precision and reliability, despite weighing only 234 g.
