SUPER RECORDDERAILLEURThe new Super Record™ 12X2 Speedderailleur: pure technology. Functionality combines with the highest quality materials & exceptional weight to generate unparalleled performance.A connector rod has been added to the new Super Record™ 12X2 Speedderailleur, as well as a unidirectionalrocker arm in carbon fibre that further reduces the weight of the component, lends uniformity to the aesthetics, & magnifies the incredible performance of Campagnolos signature component. The new Super Record™ 12X2 Speedderailleur 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 & precision of shifting; it also ensures that thederailleur is always at an ideal distance from the sprockets. The rocker arm was optimised 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 Speedderailleur is made from technopolymer plastic reinforced with carbon fibre, which contributes to the robustness & lightness of the component, whilst the titanium stop screw ensures a reduction in weight & matches even better with the technical & aesthetic aspects of the component. Weight 181 gr. FEATURES & BENEFITSOptimised spring return On rough roads, the spring positioned between the upper body & the pivot absorbs the vibrations, ensuring the chain always rest properly on the sprockets.12-tooth jockey wheel on the rocker arm Perfect for use with cassettes that have a wide range of teeth Ensures constant chain tension Adjustment of the initialderailleur position Allows for exceptional adaptation to any sprocket pack (11-29 & 11-32) Trajectory optimisation The shifting movement of thederailleur keeps the upper jockey wheel on the rocker arm at a constant close distance from the sprocket in use. Removable pivot on the upper body Perfect functionality with standard drop-out (with pivot) & direct-mount (without pivot)
