The Campagnolo Chorus EPS groupset takes a great deal of its DNA from its mechanical counterpart as it represents a more accessible version of Campagnolo performance, quality and attention to detail but delivers it in the laser-like precision package of an EPS drivetrain.
The shifting performance of the Chorus EPS groupset is exactly the same as its lighter weight siblings, Record and Super Record, making for a transmission
fit for professional racing. Shifting even under heavy load is no problem for the Chorus EPS transmission and mud, grime and debris have met their match against such powerful motors.
The EPS rear dérailleur is comprised mainly of a mechanical structure, derived from the mechanical gear and composed of a dérailleur rod/parallelogram/dérailleur cage, of a worm screw enabled by an electronic actuator. As with the dérailleur, the electronic rear dérailleur actuator is composed of a gear motor and a sensor, the built-in resolver, that reads its movements.
The geometry of the parallelogram has been made more rigid and optimized to promote interaction with the electronic parts.
The rear dérailleur is also equipped with a play recovery system using a helicoidal spring that optimizes stability and precision and keeps operation and performance constant over time, even after many kms have been covered.
As with the mechanical rear dérailleur, it is possible to optimize its position with respect to the frame and chain by acting on two adjusting screws: the screw that adjusts the mechanical end stop and the screw that adjusts the distance between the upper pulley and sprockets. By using these screws it is possible to optimize the installation of the rear dérailleur and increase the precision of its operation.
DTI: Digital Tech Intelligence is housed inside the Power Unit and it continuously monitors the signals that arrive from all the EPS components, thus managing their operation.
MULTI-SHIFTING: There are no longer any limits to Multi-shifting and the choice is at the fingertips of the cyclist.
RIDE BACK HOME: The uncoupling mechanism of the rear dérailleur is useful if the battery runs out ""on the road"", allowing you to manually ""uncouple"" the rear dérailleur to position it on which ever sprocket you require.
WATER PROOF: In order to achieve the IP67 classification, all the electronic components of the EPS system underwent a series of tests, which proved their ability to function perfectly under one meter of water for at least 30 minutes.
Rating on the entire system rain gear is only necessary for the cyclist, not his groupset.
