The Shimano CUES RD-U4020 rear derailleur delivers stable, dependable drivetrain performance across trails, gravel paths, and city streets.

Built around Shimano’s durable CUES platform, it’s engineered to handle high mileage and demanding riding conditions with consistent, smooth shifting.

Its low-profile design helps protect the derailleur from obstacles, reducing the risk of damage when riding off-road or navigating tight urban environments.

With a total capacity of 41T and support for a maximum low sprocket of 36T (2x9-speed), the RD-U4020 offers a versatile gearing range suited to recreational MTB, trekking, hybrid, and commuter bikes.

Designed and tested for long-term durability, this derailleur is also E-BIKE RATED, meaning it’s built to withstand the added torque and load of electric-assist drivetrains.

  • Designed for Shimano CUES 9-speed drivetrains
  • Stable shifting performance on trail, gravel, and urban bikes
  • Low-profile construction for added protection from impacts
  • Total capacity: 41T
  • Max low sprocket: 36T (2x9-speed)
  • E-BIKE rates for high-torque applications
  • Built for long service life and reduced drivetrain wear
