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 HG or SRAM XD / XD-R freehub body. A freehub standard cannot be adapted — the wheel either has it or it does not.

Intended for mtb builds.
