Campagnolo EPS Electronic

2009 ~

In the works for more than 20 years, Campagnolo unveiled their electronic power shift systems, "EPS", in 2012.

The first version of Campagnolo electronic shifting dates to 1992. It was developed through a partnership with Professor Magnifico, teacher of Mr. Faggin, inventor of the micro chip. In 2011, a test series of the system, called "Campy Tech Lab", was used throughout the pro season by the Pinarello Movistar team. Victories included 2 titles at the Giro d'Italia, 1 at the Tour de France, and 1 at the Vuelta di Spagna.

Now available in Super Record, Record, and Athena 11-speed groups ~

Extensive BiKyle test rides confirm the reports we received from our friends and mechanics on the pro circuit: split second shifting with nearly perfect mechanical feel is dead accurate each and every time. And the front derailleur is automatically realigned for perfect clearance after every rear shift! Our extensive testing duplicates our team mechanic reports - the groups require no further adjustment after original setup, even after weeks of intense use. Our on-the-road report - the performance of existing Campagnolo 11-speed mechanical groups is truly outstanding. But, ride a new electronic group for a 100 miles and you'll be spoiled forever. You'll never want to go back to standard mechanical shifting again.

Dave M, 5/12 - "I own a number of top-end bikes but after 2 rides on my new Pinarello Dogma 2 EPS bike I don't want to ever ride my other bikes again!"

Bike Radar, 10/12 - "Our initial impressions of Campagnolo's Super Record EPS electronic group haven't changed since we first rode it back in November 2011. In short, it's still flat-out amazing, with impeccable shift accuracy, smoothness and consistency with tactile feedback at the short-throw levers that so far is lacking in Shimano's Di2 system. Moreover, the drivetrain was whisper quiet, with nary a noticeable hum on rare occasions when our forward progress was perfectly matched by an encouraging tailwind. As expected, braking performance was outstanding, with the mixed dual/single pivot calipers and generous machined aluminum brake track on the Shamal Ultra rims. Initial bite was aggressive without being overly grabby, modulation was smooth and predictable, and lever feel was communicative and firm, just as it should be."

EPS Features ~

ErgoPower Shifters ~

Instantaneous shifting up and down via a lever and button on the inside of the brake/shifter levers. Hold the shifter button down and the gears change across the entire 11-speed cassette - up or down. The hand motion required for shifting is truly minute and access from the tops and drops of the handlebars has never been so convenient. The position of the inner lever has been improved in comparison to the mechanical controls to make it easier to use even when your hands are gripping the lower part of the handlebar. And the levers simulate the classic Campagnolo click feeling so you always know what gear you are in.

Rear Derailleur ~

Driven by a small electrical motor that operates an LED encoder located under the derailleur's outer body. A recovery system takes over in the case of accidental impact. In the case of broken parts, an option for manually moving the rear derailleur is also included. An uncoupling mechanism on the rear derailleur is available if the battery runs out on the road.

Front Derailleur ~

Driven by a small electric motor and 2 contact limit switches. Compared to traditional mechanical derailleurs that need to be adjusted manually with micro shifts, the EPS derailleur is equipped with a very sophisticated electronic AUTOMATIC POSITION CORRECTION system - no fine tuning ever needed! Depending on the sprocket that has been selected with the controls, the EPS re-positions the derailleur to optimize its position with respect to the chain. This allows chain crossovers that are not optimal in traditional systems.

Electronics ~

Electronic component located in a small digital encoder to precisely read chain position as well as chain direction and speed of motion. This information is translated into a binary code and transmitted by wireless technology for continuously updated output to the drivetrain. This Digital Tech Intelligence is housed inside the Power Unit and continuously monitors the signals that arrive from all the EPS components.

Battery ~

Called the Power Unit and positioned inside a special casing that can be placed in different places on the frame according to the manufacturer's choice.

External Cable Routing ~

Some of the most current carbon frames include internal cable routing for Campagnolo EPS and Shimano Di2 electronic shifting systems. However, external cable routing is a nice option for all other road frames. Our BiKyle mechanics take considerable time and effort to run the cables in an unobtrusive manner so they are nicely hidden yet still accessible for easy servicing.
