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