CN 7901 Dura Ace Chain 10-speed
A 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.
