Shimano CUES RD-U4010 9/10 Speed Shadow Rear Derailleur

Shimano CUES offers high cross-compatibility within the CUES family and with certain compatible LinkGlide components, allowing 9, 10, and 11-speed shifters, derailleurs, cassettes, and chains to be mixed and matched. All CUES components use the same 11-speed chain and 1:1 cable pull ratio but are not compatible with older, pre-CUES Shimano groupsets from the Dyna-Sys or HG eras due to differing standards.
