Super lightweight 11-speed HG-EV cassette with a rigid carbon and alloy carrier for excellent shifting even under the most demanding gear changes. 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 lightweight alloy and carbon carriers to reduce weight and increase rigidity. 5 largest sprockets are made from titanium to reduce weight without sacrificing strength. Sprockets are extensively cut away and drilled to further reduce weight without reducing rigidity.
•Nickel-plated finish offers hard wearing resistance to corrosion.
•Alloy cassette lockring.
