Performance without compromise
Three key words have emerged as the theme for the DURA-ACE® system: Speed, Smooth and Strength. Speed and Smooth result in effortless shifting, improved braking operation, enhanced ergonomics and an attractive feeling and design. Strength is focused on the critical need for lightweight without sacrificing rigidity, durability or precision. "100% Power Transmission" is the goal pursued by the fusion of these three concepts. Ride Dura-Ace® to see why Lance has ridden to 7 Tour de France victories aboard Dura-Ace components.
Hollowtech II® crank and bottom bracket combines race-proven hollow forging technology with the integrated crankset & bottom bracket. Weight is reduced while rigidity & power transfer is radically increased. In addition to Hollowtech II® integrated design; the crank arms are hollow which provide amazing strength and rigidity at a light weight. Finally, SG-X chainrings enable super smooth front shifting. Special tooth profiles, pick-up spikes and ramps help make the front derailleur shifts quiet, easy and trouble free for you the rider.
Shimano Dura-Ace FC-7800 Hollowtech II Crankset offers optimum balance of light weight and rigidity and features splined crank and 53-39T gearing.

Was this useful? Yes | No A bold new look for Dura Ace, the 7800 crank has elegant styling and a beautiful 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. 730g Does not include bearing cups (see item SH-SMFC7800). Specify Arm Length 170, 172.5, 175. 53/39 only.
