A bold new look for Dura Ace, the 7800 crank has elegant styling and a gorgeous finish. Shimano also shed weight while increasing stiffness and pedaling efficiency by integrating the bottom-bracket axle into the right crankarm. The spider and large chainring feature more material, which enhances rigidity, too. To minimize the weight, the crank is Shimano's Hollowtech II design. Also, the bottom bracket places the bearings further apart for rigidity and reduced friction. 730gDoes not include bearing cups (see item SH-SMFC7800). Specify Arm Length 170, 172.5, 175.53/39 only.
