This CUES FC-U4000 has a riveted 32T steel ring and 170mm aluminum arms. It uses a square-taper bottom-bracket interface and a 52mm chainline, with a recommended spindle length of 123mm.
Shimano specifies LINKGLIDE shifting-system use with a LINKGLIDE or HG 11-speed chain. The 9/10/11-speed label does not mean every drivetrain at those speeds is compatible. Check the complete system and select the required bottom bracket separately.
