This is a replacement 11T sprocket wheel for compatible 11-speed HG cassette assemblies. The built-in spacer design makes it the correct small sprocket option for the specified CS-M8000 cassette combinations, helping you refresh the part that sees the most frequent use without replacing serviceable sprockets elsewhere.
The sprocket is compatible with 11-40T, 11-42T and 11-46T cassette ranges and uses an HG spline M freewheel interface. It is listed for LINKGLIDE and HG 11-speed chains, with the recommended chain options including CN-HG901-11, CN-HG701-11 and CN-HG601-11.
For installation, face the group mark outward and align the sprocket’s wide projection with the wide groove on the freewheel body. A TL-LR15 or TL-LR10 is recommended for lock-ring work, with the lock ring tightened to 30–50 N·m. Check your cassette range and freewheel standard before ordering.
A practical choice for anyone servicing a compatible 11-speed cassette and replacing a worn or damaged 11T outer sprocket rather than the complete cassette.

Generic is a catalogue designation for products presented without a distinct store-brand identity. The term describes the retail classification rather than a separate manufacturer history or geographic origin. Generic-labelled products can still have clearly defined specifications, standards and compatibility requirements. For this component, the catalogue designation is retained while the fitment details identify the relevant road bottom bracket application.
