Shimano Dura-Ace CN-7901
10-Speed Chain
- 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.
