Shimano SLX M7100 12sp Cassette

The new shift ramp designs provide the fastest and smoothest shifts.

The CS-M8100-12 reduces cassette inactivity resulting in faster acceleration and increased chain security.

Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load

Close ratio gearing allows a more efficient use of energy through finer cadence control

Sprockets are cut away and drilled to reduce weight without reducing rigidity
