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. The highly rigid hollow structure cuts down on weight but still maintains strength resulting in better power transfer and more precise front shifting. 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.
Power Meter The Shimano FC-R9100-P power meter has a reliable, completely sealed crank-integrated design that is waterproof in all conditions.
