Twenty years and four generations in the making, Campagnolo has finally presented not just one but two electronic groups, Record EPS (Electronic Power Shift) and Super Record EPS, both with identical functionality but slight differences in weight and bearing performance just like the mechanical analogues.
While consumers are only just now seeing the production version of Campagnolo's new electronic group, the company actually first began its first development work in 1992 – back when eight-speed drivetrains and integrated brake/shift levers were still considered state-of-the-art and about a year before Mavic's first ill-fated commercial attempt.
Campagnolo's first working prototype was – like everything else in those days – an eight-speed system and the company's developers tucked the electronics and battery inside a gutted water bottle. The necessary derailleur motors and actuators were quickly deemed too heavy and bulky to be practical, though, and the idea was relegated to indefinite development status. While the company was convinced a motorized transmission represented the next logical step in terms of performance, it nonetheless also felt no pressure to bring a system to market on a specific timeline.
