Campagnolo Super Record Rear Derailleur Black 12s / Max 34t

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 fibre 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 optimised to interface with sprockets that have from 11 to 34 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
