Desviador Trasero Shimano Ultegra RX800 11-speed clutch

Descripción

The Shimano Ultegra RX800 rear derailleur is equipped with the Shadow+ technology. This technology allows the Ultegra RX rear derailleur to secure the spring of the cage. This reduces blows and vibration on the chain. The Shimano Ultegra RX800 rear derailleur is ideal to use on bad roads or on gravel. The Shimano Ultegra RX800 rear derailleur has been tested by John Degenkolb in Paris-Roubaix. The test results were praised, which is why Shimano started production of the rear derailleur directly for the consumer.
