The new Super Record 12x2 Speed rear derailleur: pure technology. Functionality combines with the highest quality materials and exceptional weight to generate unparalleled performance. A connector rod has been added to the new Super Record 12x2 Speed rear derailleur, as well as a unidirectional front rocker arm in carbon fiber that further reduces the weight of the component, lends uniformity to the aesthetics, and magnifies the incredible performance of Campagnolo's signature component. The new Super Record 12x2 Speed rear derailleur can be described as a sculpture with an innovative shape that uses 3D Embrace technology to better cradle the smaller sprockets. The technology serves a double purpose: it enables the chain to maintain optimum traction at all times, thus increasing the speed, power, and precision of shifting; it also ensures that the rear derailleur is always at an ideal distance from the sprockets. The rocker arm was optimized to interface with sprockets that have from 11 to 32 teeth, thus requiring only one version for all of the sprocket packs available. The upper body of the new Super Record 12x2 Speed rear derailleur is made of technopolymer plastic reinforced with carbon fiber, which contributes to the robustness and lightness of the component, whilst the titanium stop screw ensures a reduction in weight and matches even better with the technical and aesthetic aspects of the component.
Campagnolo's Athena EPS Rear Derailleur uses an advanced-parallelogram design that assures quick, precise shifting, while high-power servo motors make it effortless. The near-instant response is as impressive as being able to shift all 11 gears with a mere button hold. No matter what gear, the position sensor automatically adjusts for perfect alignment on every shift. And, in the unlikely event of a system malfunction, the manual release allows you to move the rear derailleur to your desired gear to get you home. Plus, the aluminum and carbon construction keeps weight low and boosts strength and the pulleys are made from a special rubber for whisper quiet drivetrain action.
