High performance Shimano HG-EV 11-speed road cassette
Hyperglide EV 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.
Largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity.
Sprockets are cut away and drilled to further reduce weight without reducing rigidity.
Pearl-bright steel cassette lockring.
