The new 5.5 millimetre thickness has been combined with new materials and a special anti-friction treatment which permits outstanding fluidity.

We have reduced the width of the chain to 5.5 millimetres with the new spacing and a new material has been envisaged for the outer links. The pins are hollow inside to reduce the weight while maintaining strength. It is necessary to use tool UT-CN300 to fit it. The Ni-PTFE treatment ensures smoothness and long life. The Ultra-Link™ fastening system guarantees strength and operation with the new 11-speed sprockets.

The super-narrow, lightweight Shimano Ultegra CN-6700 10-speed directional chain provides optimal cassette and chainring interaction for lightning quick shifts and maximum power transfer. Shifting precision has been significantly improved using different inner and outer plate chamfers and dimensions to accommodate the different shifting requirements of a chain moving inward or outward on the drivetrain. The outer plate design significantly reduces the chance of chain suck, while the inner plate provides better contact with the gears for smoother shifting under high loads.

The new asymmetric design of the Dura-Ace chain has redesigned plates that improve the contact interface with the cogs and reduce the chance for chain suck on the chainrings. Other improvements to the links provide greater durability and life with less noise and smoother function. The chain uses hollow pins and weight drops by over 18 grams even with the addition of a quick connection / removal link. A departure from the traditional Hyperglide connection pin, the SM-CN79 quicklink provides a reusable connection and removal point for the chain. The quicklink can be used on any Shimano 10-speed chain and the new chain can also be joined by a traditional Hyperglide 10-speed connection pin if necessary.

• Innovative outer plate shape: for reducing chain suck
• Redesigned outer & inner plates: for improved contact with gear teeth and smoother shifting<.li>
• Hollow pin: weight saving
• Perforated plate: weight saving
• Quicklink: for easy chain connecting without use of tools
