SHIMANO ULTEGRA RX RD-RX805 DI2 Shadow + Rear Derailleur Medium Cage GS 11-Speed

The Shimano Ultegra RX805 GS Di2 11-speed derailleur is the sister derailleur to the Ultegra R8050 Di2 derailleur but features a "clutch," or what Shimano calls Shadow RD Plus technology. This is designed to reduce chain slap, noise and improve chain retention on bumpy riding surfaces. It is ideally suited to cyclocross, gravel, and adventure riding. With its GS long cage, the derailleur is compatible with up to a 34 tooth cog. With Di2, you get fast, reliable, electronic shifting that is completely customizable via the E-TUBE Project.
