As good as it gets.
The world has come to expect nothing but the best from Campagnolo, so it should come as no surprise that the innovative Electronic Power Shift system is nothing if not astounding. The Super Record 11 EPS Front Derailleur is a celebration of harmony between alluring Italian design and the most innovative front derailleur that Campagnolo has ever created. After twenty years of research, development, and testing, the wait is over, the word is out, and the face of the game is forever changed. Campagnolo EPS is here.
The Super Record 11 EPS Front Derailleur is a technological marvel. Like the Super Record 11 EPS Rear Derailleur, it operates off of an electronic actuator comprised of a gear motor and an electronic sensor. Where it differs is in the details. The gear motor for the front derailleur's electronic actuator has been developed with a Swiss company that manufactures electric motors for space missions to Mars. Really. It operates with a high over-torque transmission resulting in a high gear ratio for precise strong pulls. The electronic sensor utilizes Magnetic Hall Sensor Resolver technology that both physically and digitally isolates the electronic sensor from terrain vibration, guaranteeing a constantly precise functionality for the derailleur's positioning and shift.
Campagnolo has spent a great deal of time on the Super Record 11 EPS front derailleur to guarantee precision by eliminating terrain vibration and maximizing rigidity. The frame-derailleur fixing system is comprised of an aluminum polymer blend, and has been co-molded with the derailleur body. The external derailleur rod, which works in conjunction with the electronic actuator, is held by a hollow hub and double wing with a double-finned pin passing fully through to achieve maximum stiffness. Additionally, the electronic actuator is housed in a cascade gearbox that minimizes vibration and allows movement to be transferred precisely. As for the monolithic derailleur body, it is constructed from a beautiful and efficient technopolymer-carbon blend that halts vibration and assures proper derailleur fork positioning.
Campy freaks can still spot the DNA of the mechanical Super Record in this EPS version, but of course with some high-tech twists. Most notably is the EPS exclusive, theAutomatic Position Correction system. APC is an auto-trim feature that permits any chain line combination without cage rub or risk of throwing the chain. To accommodate chainring shifts from these unique cassette positions, Campagnolo developed Extra Stroke technology that momentarily over- or under-compensates the derailleur movement during shifting to avoid pitching the chain. This is further enhanced by Campagnolo's decision to retain mechanical Super Record's XPSS technology. Extreme Performance Shifting Systems utilizes eight up-shift sectors of the large chain ring and two down-shift sectors of the small ring to ensure the smoothest and most direct chain transfer possible. Campagnolo has seamlessly integrated necessary mechanical Super Record technology into EPS, but injects heightened performance every step of the way.
Another achievement of EPS is the ability for real-time user correction, and Campagnolo's dedication to protecting componentry. The user of the Super Record 11 EPS front derailleur has been given the power to perform Micro Adjustment to the rear derailleur on the fly by engaging Ride Mode from the Switch Mode button on the Super Record 11 EPS Ergopower Shift Levers. This enables the derailleur to make seven incremental adjustments, at 0.1mm per adjustment. The Super Record 11 EPS front derailleur is also IP67 compliant, a rigid international standard for electronics that requires protection of electronic components from water and dust alike. To give you an idea of how stringent this test is, every Campagnolo EPS component has to operate perfectly while submerged under water for 30 minutes.
Campagnolo has relentlessly pursued perfection in their creation of the Super Record 11 EPS Front Derailleur, and along the way, have changed the performance expectations of front derailleurs forever. A work of art, and a pinnacle of design, the Super Record 11 EPS Front Derailleur proves that some things are worth the wait.
