The most representative piece of the new Shimano Ultegra R8000 group. The Cobra has been completely redesigned, with a new design inspired by the Dura-Ace group. Thanks to the hollow arms, the crank is extremely light, without sacrificing stiffness and strength. The crank spider has been equipped with 4 arms, which also has a positive effect on weight, and the transfer of energy from the crank to the rest of the drivetrain.
More clearance between the chain and the teeth makes the crank compatible with O. L. D. frames.
The Ultegra FC-R8000 is available in five different disc combinations, and four crank arm lengths. Properly beveled teeth make it easier to flip gears and improve chain action.
