Campagnolo Super Record 12 Speed Rear DerailleurThe 12-Speed Campagnolo Super Record Rear Derailleur is the heart and soul of the Super record 12-Speed drivetrain. Super Record components are designed for competitions and to provide the optimum performance required to win at the top level. This new model still provides professional racers with the certainty of fast and exceptionally accurate shifting, even under load. However, you don't have to be a professional to take advantage of Campagnolo's best performance features, the significant increase in shifting will be noticeable to any road cyclist.More Efficient, Better Power Transfer, Smoother ShiftingThe revised shape of the external components of the Super Record 12-Speed rear derailleur allows it to move efficiently to give maximum performance at any angle across any cassette ratio. The design of the cage keeps the chain closer to the cassette to ensure better power transfer, a more positive drive, whilst perfectly following the curve of the cassette sprockets. This better chain/sprocket interface also gives greater durability of components and is silent during use.Features: ULTRA-LIGHT main derailleur body Stiffer, less weight Optimised trajectory curve, improved shifting Close contact with each sprocket 3D-Embrace Technology Inner mechanism embraces more teeth per sprocket Greater shifting retention and efficiency Unique 72.5mm Cage, One Size Fits All (11-29 and 11-32T cassettes) Larger 12-Tooth pulley design, greater contact and cassette versatility Increased adjustability, durability and rider safety Massive performance increase and just 3 grams difference, compared to the previous model Weight: 181gBuy Campagnolo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
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. 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 techno-polymer plastic reinforced with carbon fibre, 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. Technologies: Upper body in ULTRA-LIGHT technopolymer reinforced with UD Carbon Fibre3D Embrace Technology: Movement of the rear derailleur is designed to make the chain embrace more teeth per sprocket to guarantee maximum traction,Optimised trajectory: Movement of the rear derailleur means that the upper pulley wheel is at constant distance to the sprocket in use, 12-tooth pulley wheels: Perfect for cassettes that have a wide range of teeth,Optimised return spring: This guarantees constant chain tension regardless of road vibration,Versatile Hanger System: Standard or Direct mount hanger, perfect compatibility of rear derailleur with any frame: disc or rim, direct mount or classic hanger,. Key Features:Constant precision: On rough roads, the spring positioned between the upper body and the pivot absorbs the vibrations, ensuring the chain always rests properly on the sprockets,The pulley wheels on the 12-tooth derailleur cage allow the chain to move more smoothly,The initial position of the rear derailleur can be adjusted to suit any cassette,Easy wheel replacement: The rear derailleur is positioned further back, making it easier to slide the wheel out and replace it,Removable pivot on the upper body: Perfect functionality with standard drop-out (with pivot) and direct-mount (without pivot),Weight: 181g.
