Shimano Dura-Ace Hollowtech II Road Bicycle Crankset 11s FC-9000 52-38T

With a unique four-arm spider and Hollowtech II construction putting strength just where its needed, Shimano's Dura-Ace FC-9000 11-speed Crankset sets new standards for stiffness and low weight. On the surface, the FC-9000 is a complete departure from the traditional aesthetics of Dura-Ace. Gone are the days of the five-arm spider, with their new four-arm design allowing cyclists to run either compact or standardr rings on one spider, while shaving weight. The FC-9000 ds however keep Shimano's Hollowtech II construction. Strategic placement of hollow aluminum throughout the crankset and chainrings allows more structural material to be used, and when coupled with Shimano's integrated bottom bracket, creates a superior crankset more stiff, lightweight, and reliable.172.5mm 52-38T Shimano FC-9000 CranksetHollowtech II & Hollowglide construction4 arm spider design allows compact and standard ring sizes110mm Shimano Dura-Ace SM-BB9000 bottom bracketCompatible with Shimano Dura-Ace 9000Claimed weight: 637g
