Shimano introduces carbon Dura-Ace crankset
At Eurobike Shimano introduced a carbon fiber Dura-Ace crankset. The FC-7800C has an aluminium core to realize a lightweight yet very rigid construction. By using this technology, Shimano developed a crank set that combines the best of both materials. The aluminium frame ensures a stiff set-up for optimal power transfer while the carbon saves weight.
