    Elite road racers demand reliable and precise shifting, 11-speed Dura-Ace R9100 delivers with its super-lightweight yet durable design

    Lighter and intuitive shifting operation thanks to toggle link leverage construction

    Thanks to improvements in the cage design outer trim is no longer required allowing the rider to focus on racing

    Extra wide pivot link and optimised spring tension gives a rigid, flex free shift while being smooth and light action

    Forged aluminium construction reduces weight without sacrificing durability

    Hard-wearing finish expected of Dura-Ace

    Integrated cable tension adjustment

    Maximum capacity of 16 teeth, for use with outer rings 50-55T
