Shimano
7900 Dura-Ace 10-Speed Chain

• Top of the range Dura-Ace Super narrow lightweight 10-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

• Comes with optional SM-CN79 reusable Quick Link for easy installation and removal without the need for tools
• Hyperglide (HG) series 10-speed compatible chain
• 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
• Weight - 252g 115 links
