Shimano Dura-Ace 9000

Dura-Ace 9000 chainset employs an innovative four-arm spider, that is bound to start a new trend, and the more usual Hollowtech II construction to save weight.

Stiffness is supposedly the same as with the 7900 cranks.

Dura-Ace 9000 chainset is 11-speed specific.

Now the bolt circle diameter of the Dura-Ace 9000 chainset is the same for compact and traditional cranks, giving more opportunity to mix and match gearing if you so desire.
