12-Speed Cassettes
5 cassettes that work with a 12-speed drivetrain. Speed compatibility here comes from each part's recorded specification, not from guesswork — mixing speeds across a drivetrain is the single most common upgrade mistake.

Fitment values come from each component's recorded manufacturer specification. A dash means the value is not recorded for that part, not that it fits everything — check the individual component page.
