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. In numbers: weight of this crank set (including bottom bracket) is 709 grams and it is 10% stiffer than the aluminium Dura-Ace crank set FC-7800 that is already famous for its rigidity.

FC-7800C has been developed with Shimano’s proven HOLLOWTECH II technology with an integrated bottom bracket. It uses identical bottom bracket bearing cups as FC-7800. The left crank arm features the same installation technology as current Shimano XTR to save some weight and to make installation even easier.

This state-of-the-art crank set will be available in gear combinations 53/39T and 52/39T in crank arm lengths 170, 172.5 and 175mm.

Michael Boogerd (Team Rabobank) and Markus Fothen (Team Gerolsteiner) have taken this crank set already to the ultimate test: the Tour de France. The crank set will be available as after market product from spring 2008.
