The Shimano Rear Derailleur 2x11s Di2 is designed for riders who demand fast, precise, and effortless shifting on modern 2x11-speed drivetrains. As part of Shimano’s Di2 electronic shifting ecosystem, this rear derailleur replaces traditional cable actuation with electronic signals, delivering crisp, repeatable gear changes at the touch of a button. Whether you are sprinting, climbing, or rolling along in the bunch, the derailleur is engineered to maintain accurate chain positioning across the cassette, helping you stay in the right gear with minimal effort.
Built around Shimano’s proven reliability, this 2x11-speed Di2 rear derailleur is suitable for performance-oriented road setups and is typically paired with matching Di2 shifters, front derailleur, and an 11-speed cassette. The electronic system reduces the need for frequent adjustment, as the derailleur automatically maintains alignment once set up correctly. Its compact, refined design integrates neatly with the bike, while the robust construction is made to withstand regular training and racing conditions. For riders upgrading from mechanical shifting, this derailleur offers a noticeable improvement in shifting consistency, especially under load or in adverse weather.
