Rear

Campagnolo's Super Record EPS Rear Derailleur's arresting beauty is entwined with the pinnacle in rear shifting accuracy and precision. Campagnolo uses an advanced-parallelogram design and the extremely high-quality servo motors for precise, fast shifting of up to all 11 gears from a single push of a button. Or stop on any cog and the position sensor makes micro-adjustments to ensure perfect alignment. And this top-tier Italian bike jewelry is constructed from carbon and cold-forged aluminum to create an ultra strong and extremely light derailleur. Plus, the pulleys roll on super-efficient ceramic bearings and are made from a special rubber that renders the drivetrain virtually silent.

The heart of the connected cadre. The SRAM RED eTap AXS rear derailleur is AXS enabled for easy personalization and designed for both 1x and 2x systems.

It's an all-new derailleur that's specifically designed and optimized to be motor-driven instead of cable-actuated. AXS powered components enable customization and scale to an individual rider's liking via the AXS App. It features a shorter cage for 10mm more ground clearance, with more chain wrap on the cassette to sit slightly further forward, and further inboard from mechanical Eagle. The Eagle AXS derailleur is smart enough to protect itself thanks to its incredibly resilient Overload Clutch. In the event of an impact, the motor gearbox disengages, giving the derailleur freedom to move, and instantly returns back to its position for a seamless experience for the rider. The system is tested to IP69K water and dust proofing standard for creek crossings, mud splatterings and the resulting post-ride pressure washings. - Enduro focus and trail ready - Forged aluminum cage - Stainless hardware - Black/Polar colorways - Eagle technology - Overload Clutch protection - AXS enabled componentry software that makes it possible to both program and personalize new SRAM and RockShox components - System is completely water and dust proof to IP69K - Eagle AXS is designed to work with X-DOME Eagle cassettes only, providing the most precise, silent, and reliable shift performance available.

More than a mechanical derailleur with a battery and a motor bolted on, the Eagle AXS derailleur is the heart of the whole AXS system.

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.
