Super narrow lightweight Ultegra 6701 10-speed directional chain for optimum cassette and chainset interaction and maximum power transfer (recommended for use with double systems only). 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 pedaling, increased rigidity and near silent running.

• Chain uses a directional design with specifically shaped inner and outer plates to optimize shifting over the chainset and cassette
• 5.88mm chain width optimized for 10-speed Super Narrow HG drivetrains
• Weight: 267g
