Designed for fitness and E-Bike use, the Shimano CUES RD-U4020 rear derailleur is ideal for carefree riding in the city and in nature. In doing so, the rear derailleur for 2x9-speed drivetrain systems convinces with reliability in everyday use and a smooth, defined shifting behavior.
The flat design and the Shadow RD chain stabilization system provide safety reserves in rougher terrain. When paired with a Shimano LinkGlide cassette (sold separately), the RD-U4020 rear derailleur provides smoother, quieter pedaling and barely noticeable shifting.
Exclusively compatible with the Shimano LinkGlide shifting system.
