Shimano CUES RD-U6000-GS 1x 10/11-Speed Rear Derailleur Medium Cage

Shimano CUES — Built for Versatility, Durability & the Long Haul

The Shimano CUES RD-U6000-GS is a 1x 10/11-speed rear derailleur from Shimano's CUES ecosystem — a range designed to simplify compatibility across MTB, gravel, hybrid, trekking, and city bikes. Whether you're on trail, gravel, or road, the RD-U6000 delivers smooth, reliable shifting backed by Shadow RD+ chain stabilisation and LINKGLIDE technology that's up to 300% more durable than standard HyperGlide drivetrains.

The GS medium cage suits most 1x setups with up to 48T (10-speed) or 50T (11-speed) cassettes. Part of Shimano's growing CUES lineup which is gradually replacing Acera, Alivio, Deore and Tiagra across multiple disciplines.
