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.
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.

HG Cassette
Precisely positioned shift ramps and tooth profiles help control the chain during shifts, delivering fast and responsive indexed shifting.
DYNA-SYS 11
The 11-speed system provides useful climbing range while maintaining closely spaced gear steps for a smooth pedalling rhythm.
Wide cassette sprocket
The broad cassette range gives you more low-gear capacity for demanding climbs without sacrificing useful intermediate ratios.
Rhythm step gear progression
Carefully spaced ratios support efficient pedalling and stable shifting across changing terrain.
Combination of aluminium and steel gears
The cassette combines lightweight aluminium components with durable steel gears to balance low weight, reliability and long service life.
