  • Shimano Dura-Ace R9100 Cassette

    Shimano's Dura-Ace R9100 Cassette has been designed to be as lightweight as possible. The cassette's sprockets are made from alloy and carbon, reducing its overall weight without compromising on durability. Featuring Hyperglide EV sprockets, which are computer designed for ultimate performance, this cassette provides quick shifting for whatever the trails throw at you. 


    • Materials: Spider Arms: CFRP (Carbon Fibre Reinforced Polymer) & Alloy; Sprockets: Alloy & 5 Titanium sprockets for lightweight performance
    • 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 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
    • All cassettes in the range will be compatible with the one rear derailleur so you can easily swap your cassettes out based on terrain.
