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. And the new chain can also be joined by a traditional Hyperglide 10-speed connection pin if necessary. Some of the features of the new chain include: Innovative outer plate shape, for reducing chain suck, redesigned outer & inner plates for improved contact with gear teeth and smoother shifting and perforated plating which reduces weight.
