For 2015 there is a new geometry of the mech cage and a NEW software giving different cage strokes. The Campagnolo EPS drivetrain is an organic set of mechanical and electronic components that work together in an integrated way to guarantee maximum performance.
In particular, the EPS derailleur interacts with the mechanical crankset and enhances the elevated derailleur speed and precision made possible with X.P.S.S. technology. The 8 special upward zones and 2 downward zones for the chainrings associated to the speed and precision of the new EPS derailleur guarantee top performance.
The derailleur is composed of a mechanical structure with dropout and a series of electronic parts. The outer Derailleur Rod held in place by a double-finned pin that passes all the way through to increase rigidity. The System that links the derailleur to the frame is made of aluminium co-pressed with the engineering polymer of the body of the derailleur. This creates optimal solidity and rigidity ensuring that the derailleur maintains a correct position with respect to the frame. The core of the derailleur 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.
