FC-7800C has an aluminium core and is super-stiff
The aluminium core ensures a stiff set-up for optimal power transfer while the carbon saves weight, said Shimano. Theweight of the crankset (including bottom bracket) is 709 grams and is 10 per cent stiffer than the aluminum Dura-Ace crankset FC-7800.
FC-7800C has been developed with Shimano’s Hollowtech II 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.
The crankset will be available in gear combinations 53/39T and 52/39T in crank arm lengths 170, 172.5 and 175mm.
