Shimano RD-U4000 CUES Rear Derailleur 9-Speed
CUES — Shimano's new everyday standard
CUES replaces the old Altus, Acera and Alivio tiers with one system that works across 9, 10 and 11 speeds. Linkglide internals mean the parts last several times longer than the groupsets they replace.
Best for: Commuters, hybrids and entry-level mountain bikes — and e-bikes, where Linkglide really earns its keep.
