The Dura-Ace 9000 cranks represent a radical departure from traditional crank design resulting in unrivaled performance. Utilizing a new x-shaped spider, Shimano was able to do away with the fifth arm, lowering the weight. They were somehow able to do this while retaining the stiffness of their previous five arm 10 speed version.

Q: Can I use this crankset in a Madone 4.5 with BB90? Also I have Ultegra's 10 Speed Drivetrain, there will be a problem?
A: It is recommended to stay with a 10 speed crankset rather than using an 11 speed, however, this 11 speed crankset should work with your 10 speed drive train.
