Nobody said that making an electronic shifting system would be easy, but Campagnolo doesn’t think of engineering in terms of easy, they think in terms of necessity. For twenty years, Campagnolo engineers have been obsessed with creating the most precise rear derailleur in the world, and the Super Record 11 EPS Rear Derailleur is the ultimate achievement thus far. In Super Record 11 EPS ,Electronic Power Shift, Campagnolo uses electronic shifting as an opportunity to enhance the performance of the esteemed Super Record series, not to simply go along with the electronic zeitgeist. What they have created is the pinnacle of Italian performance, and the object of desire for every bike aficionado on the planet. Campagnolo EPS is here, and there’s no going back.Simply put, the Super Record 11 EPS Rear Derailleur is smart. It operates off of an electronic actuator comprised of a gear motor and a built-in resolver sensor. The actuator controls a worm screw, in the place of a mechanical spring screw, to move the derailleur. In turn, the actuator’s resolver sensor is in constant communication with Digital Tech Intelligence, the brains of the system, charting every movement of the derailleur and positioning it optimally relative to the cassette. The relationship between the electronic actuator and DTI brings an exciting new feature to EPS:Multi-Shift Technology. The new Multi-Shift enables a shift through all eleven cogs, up or down the cassette, in one compression of the shift lever, and in one and a half seconds. You read that right. To help alleviate the necessity for auto-correction, Campy studied the detrimental effects of vibration on electronic components, and applied tin to the electronic actuator to reduce play. Going even further, the Campagnolo engineers bolstered the strength and rigidity of the derailleur by creating a parallelogram carbon fiber derailleur cage with an alloy inner plate.
