Rear Derailleur Shimano CUES RD-U4000 GS 9-speed

The Shimano CUES RD-U4000 LINKGLIDE 1x9-speed rear derailleur with SHADOW RD technology delivers smooth and dependable shifting performance on trails, gravel roads and city streets alike. This versatile drivetrain component is engineered for uninterrupted riding enjoyment and efficient power transfer.

LINKGLIDE technology ensures noticeably smoother and more consistent pedalling during gear changes. The optimised derailleur design provides seamless transitions between sprockets, reducing shift shock and preventing jumps that can disturb pedalling rhythm. This advantage is especially important under higher loads and on e-bikes, where drivetrain stress is greater.

The low-profile construction is optimised for off-road riding and better protected against obstacles. Refined geometry and spring tension help reduce chain drop, ensuring stable drivetrain performance. The RD-U4000 is designed and tested for long-lasting durability, including demanding e-bike applications.
