Product Info
High performance 9-speed cassette. 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. Six largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity. Double rivets on the 34T sprocket to the alloy spider for increased rigidity.
