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 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.
