As with the mechanical parts, the rear derailleur represents the pride and joy of the EPS project and encompasses a series of technologies and innovations that allow shifting speed to be optimised and guarantee unprecedented precision, even in the case of multiple shifting with 11 sprockets at a timeThe EPS rear derailleur is comprised mainly of a mechanical structure, derived from the mechanical gear and composed of a derailleur rod/parallelogram/derailleur cage, of a worm screw enabled by an electronic actuator. As with the derailleur, the electronic rear derailleur actuator is composed of a gear motor and a sensor, the built-in resolver, that reads its movementsThe geometry of the parallelogram has been made more rigid and optimised to promote interaction with the electronic partsThe lower and upper bodies, the parallelogram and the carbon derailleur cage are moved by a screw system and lead worm screw (not a spring screw) which, in turn, is enabled by the electronic actuator that communicates with the DTI. The built-in resolver inside the actuator is capable of reading the movements of the rear derailleur at any time and optimising its position by communicating with the DTI (Digital Tech Intelligence)The rear derailleur is also equipped with a play recovery system using a helicoidal spring that optimises stability and precision and keeps operation and performance constant over time, even after many kms have been coveredAs with the mechanical rear derailleur, it is possible to optimise 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 optimise the installation of the rear derailleur and increase the precision of its operationDTI: 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 operationMULTI-SHIFTING: There are no longer any limits to Multi-shifting and the choice is at the fingertips of the cyclistRIDE BACK HOME: The uncoupling mechanism of the rear derailleur is useful if the battery runs out on the road, allowing you to manually uncouple the rear derailleur to position it on which ever sprocket you requireWATER 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
