Shimano CN 7901 Dura Ace Chain 10-speedA legend sharpened to a new level of perfection. Providing the ideal symbiosis of lightweight, stiffness and performance. and finally out there to set new standards in professional cycling.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.
