Rear Derailleur SH RD-U6050 10-speed GS 03015388

Shimano CUES RD-U6050 is a Di2 electronic rear derailleur designed for touring and electric bikes using 1x10 speed systems with LinkGlide cassettes. It offers intuitive automatic shifting that frees the rider from having to think about the exact gear – the system shifts gears automatically based on riding dynamics. It features a Free Shift option, allowing shifting without pedaling.

The mechanism is designed with a low profile (Shadow RD) to protect against impacts and ensure quieter operation. It mounts directly to the frame and supports a medium cage suitable for cassettes up to 43T. It connects via a Di2 cable (EW-SD300), works smoothly under load, and is a reliable choice for daily, touring, and e-bike riders.
