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. It's extremely powerful motors are capable of producing levels of torque without rival in electronic shifting which guarantee precise and effective shifting no matter the conditions or circumstances. 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. With an IP67 waterproof rating on the entire system rain gear is only necessary for the cyclist, not his groupset. The dérailleur is composed of a mechanical structure with dropout and a series of electronic parts. The outer Dérailleur Rod held in place by a double-finned pin that passes all the way through to increase rigidity. The System that links the dérailleur to the frame is made of aluminium co-pressed with the engineering polymer of the body of the dérailleur. This creates optimal solidity and rigidity ensuring that the dérailleur maintains a correct position with respect to the frame. The core of the dérailleur is composed of an electronic actuator; in turn composed of a gear motor with a built-in resolver that uses Magnetic Hall Sensor technology (as the sensor is not in contact it is not affected by the vibrations generated by the terrain, and is therefore always precise). The gear motor was developed in partnership with a Swiss company that produces electric motors used in missions to Mars. The actuator is also equipped with a ""cascade gearbox"" which allows movement to be transferred in an exact and rapid manner. AUTOMATIC CORRECTION: Compared to the traditional mechanical derailleur that could be adjusted with micro displacements made by acting on the levers manually, the EPS dérailleur is equipped with a very sophisticated electronic AUTOMATIC POSITION CORRECTION system. 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. WATERPROOF: 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.

With this Shimano Ultegra Di2 front derailleur board your ride, quick and smooth front shifting is guaranteed under all circumstances, even when you’re shifting to the large chainring while riding out of the saddle. Due to Shimano Synchronised Shift, the front derailleur will shift automatically when the rear derailleur is shifted, allowing both of your road bike's Shimano Di2 derailleurs to work together efficiently. Customisable Electronic Shifting With the Semi- Synchronised Shift feature that’s also on the Shimano Ultegra Di2 R8050 front derailleur, it’s the other way around. The rear derailleur shifts automatically when the front derailleur is shifted, obtaining optimal front/rear gear positioning. At the same time, Di2’s auto-trim feature will automatically centre the front derailleur precisely around the chain, avoiding chain rub as you move the chain across the cassette. This is how fast, precise and smooth your shifting can be.
This stunning model features oversized 13T pulley wheels, updated Shadow RD+ mechanism and is tailored specifically to provide maximum chain retention and shifting accuracy across the new Shimano 12-Speed drivetrain transmission system.
