With a unique four-arm spider and Hollowtech II construction putting strength just where it's needed, the Shimano Ultegra FC-6800 crankset attains new standards for stiffness and low weight. Not only has Shimano eliminated the fifth chainring bolt, but it uses this new bolt pattern to accommodate both compact and standard chainrings on the same crank. Additionally, Shimano's super-stiff Hollowglide chainrings are available from the factory in a wide variety of sizes, including 36 x 52. 11-speed compatible.
