Shimano 11 speed Dura Ace Hollow pin chain

    Top of the range Dura-Ace Super narrow lightweight 11-speed directional chain for optimum cassette and chainset interaction and maximum power transfer
    Chain uses a directional design with specifically shaped inner and outer plates to optimise shifting over the chainset and cassette
    Outer plate design has been developed to reduce the chance of chain suck
    The inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity, and near silent running
    Hollow link pins offer great weight savings
    Hyperglide (HG) series 11-speed compatible chain
    Durability is assured through a chromising treatment on link pins, and the heat treatment of rollers, pins, and plates
    Zinc-alloy silver finish offers the longest lasting and best resistance to corrosion
