Campagnolo Super Record 12-speed RD20-SR124 rear derailleur

The Campagnolo Super Record rear derailleur is a state-of-the-art transmission component, featuring a particularly attractive design and crafted using carbon fibre to minimise the derailleur's weight. Thanks to 3D Embrace technology, the derailleur is designed so that the chain wraps around the smallest sprockets to maintain optimal traction, allowing for powerful, precise and fast gear changes.The pulley train has a specific design for efficient operation with 11-34 cassettes in particular, allowing Campagnolo to offer a single derailleur for all sprocket sizes, providing the same high level of performance and excellence.
