With its distinctive and unique four-arm spider and Hollowtech II construction putting strength only where it's needed, Shimano's Dura-Ace 9000 crankset pushes the bar further in stiffness and low weight. Shimano has eliminated the fifth arm allowing the new bolt pattern to accommodate both compact and standard chainrings on the same crank.
