Shimano Dura-ace 10 speed chain for use with 7800 or 7900 groupsets. Top of the range Dura-Ace Super narrow lightweight 10-speed directional chain for optimum cassette and chainset interaction and maximum power transfer. This chain uses a directional design with specifically shaped inner and outer plates to optimise shifting over the chainset and cassette. The outer plate design has been developed to reduce the chance of chain suck whilst 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. The hollow link pins and perforated inner link plates offer great weight savings.

The new Shimano Dura Ace chain is hyperglide (HG) series 10-speed compatible and durability is assured through a chromising treatment on link pins, and the heat treatment of rollers, pins, and plates.

5.88 mm chain width, optimised for 10-speed Super Narrow HG drivetrains. Zinc-alloy silver finish offers the longest lasting and best resistance to corrosion. 115 links
