Campagnolo Super Record EPS Rear Derailleur (RD19-SR12EPS)

The Campagnolo Super Record EPS Rear Derailleur (RD19-SR12EPS) is the high-performance electronic evolution of Campagnolo’s 12-speed flagship. Unlike the newer "Wireless" generation, the EPS (Electronic Power Shift) system uses a central power unit and internal cabling—similar to Shimano's Di2—to deliver consistent, high-torque shifts. It features the innovative 3D Embrace technology, which allows the upper pulley to follow a trajectory closer to the cassette for increased chain wrap and better power transfer. Built with a combination of unidirectional carbon fiber and titanium, this derailleur includes a unique UnLock System, allowing the rider to manually move the derailleur into a desired position in the event of a system malfunction or impact, effectively acting as a fail-safe during races.

Key Features

• EPS Digital Intelligence: Communicates with the DTI (Digital Tech Intelligence) to ensure the chain is always in the optimal position for the selected sprocket.

   

• 3D Embrace Technology: Maintains a constant distance between the pulley and the sprockets for more precise shifting across the entire 11-29T or 11-32T range.

   

• Magnetic Hall Sensor Resolver: A specialized sensor that ensures the derailleur always knows its exact position, providing laboratory-level accuracy in every shift.

   

• Multi-Shifting Capability: Allows the rider to shift through all 12 sprockets in a single continuous movement by holding the shift lever down.

   

• IP67 Waterproofing: Fully protected against dust and water immersion up to 1 meter for 30 minutes, ensuring reliability in the worst racing conditions.
