Shimano Ultegra R8050 Di2 11-Speed Rear Derailleur, GS
Electronic shifting with precise and perfected movement across your rear derailleur, the Shimano Ultegra R8050 Di2 11-Speed Rear Derailleur, GS is a refined choice that provides the highest levels of technical accuracy in your groupset, allowing you the smoothest shifting experience possible.
A programmed automatic motion allowing you to range across your gearing at the simple touch of a button, this derailleur is reducing its reliance on mechanical cabling, which is more prone to contamination, corrosion and stretching. With a high tolerance, cold forged aluminium link plates and a body construction providing a light net weight as well as a strong, robust build quality, this derailleur makes use of four self-lubricating micro-machined fluorine-coated link pivot bushings, leading to greatly reduced friction throughout the course of your ride.
Compatible with 11-speed cassettes and Shimano Di2 levers, this electronic rear derailleur uses a low profile shadow design construction, keeping your derailleur close, reducing the risk of damage in the lamentable event of a crash, or just in daily use. This derailleur is compatible with a maximum 34 tooth sprocket and good down to 11T.
