This Shimano Dura Ace FC-R9100 HOLLOWTECH II Crankset (2x11-speed) is wider than its predecessor but is still very lightweight by utilising the Hollowtech II technology.

Equipped with the Shimano FC-RC9100-P power meter, this crankset gathers real-time accurate and reliable power output data so you can track and analyse every detail of your ride to fine tune your training and racing program.
