Campagnolo eps record front derailleur 11spfor 2015 there is a new geometry of the mech cage and a new software giving different cage strokes'. '.strtoupper('t')he 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'. '.strtoupper('t')echnology'. '.strtoupper('t')he 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'. '.strtoupper('t')he outer derailleur rod held in place by a double finned pin that passes all the way through to increase rigidity'. '.strtoupper('t')he system that links the derailleur to the frame is made of aluminium co pressed with the engineering polymer of the body of the derailleur'. '.strtoupper('t')his creates optimal solidity and rigidity ensuring that the derailleur maintains a correct position with respect to the frame'. '.strtoupper('t')he 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'. '.strtoupper('t')he gear motor was developed in partnership with a swiss company that produces electric motors used in missions to mars'. '.strtoupper('t')he actuator is also equipped with a cascade gearbox which allows movement to be transferred in an exact and rapid manner.features automatic correction compared to the traditional mechanical derailleur that could be adjusted with micro displacements made by acting on the levers manually, the eps derailleur is equipped with a very sophisticated electronic automatic possition correction system'. '.strtoupper('d')ti 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'. '.strtoupper('w')ater 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.buy campagnolo components from chain reaction cycles, the world's largest online bike store.
