Silent as a shadow.

With Shimano's new Shadow technology at play in their redesigned Ultegra Di2 Derailleur, Shimano is ensuring that you get effortlessly easy, intuitive shifting all ride long. With a redesigned body, the Ultegra RD-R8050's sleek integrated appearance and optimized slant angle improve the responsiveness, performance, and stability of shifts. With their Synchronized Shift technology, the front and rear derailleurs communicate with each other to ensure that you're always in the optimal gear placement, shifting the front derailleur automatically with the rear, or vice versa.

The Shimano Ultegra Di2 RD-R8050 Rear Derailleur is available in two sizes, the Short Cage SS version will accept up to a 30T rear sprocket, while the Medium Cage GS version will accept up to a 34T sprocket.
