Cassette
Shimano XT CS-M8100-12 (10-51T)
12-speed 10-51T Hyperglide+, Micro Spline, alloy 45/51 cogs
$144.95 best current price across tracked retailers
What this fits
12-speed drivetrains. Mixing speed counts across shifter, derailleur, chain and cassette is the most common upgrade mistake — check every part in the chain, not just this one.
Requires a Shimano Micro Spline freehub body. A freehub standard cannot be adapted — the wheel either has it or it does not.
Intended for mtb builds.
