Shimano Dura-Ace FC-R9100-P crankset with powermeter without chainring 11-speed

Dura-Ace R9100

The new Dura Ace from Shimano is the answer to the question many professionals and ambitious amateurs have about whether and how the already incredibly high level of performance can be further enhanced. Each individual Dura Ace R9100 component is designed to work as efficiently as possible with all other components of the system. This clearly reflects the core of Shimano's philosophy of system-engineered components. The result is called System Supremacy - the superiority of the system over the sum of its parts.

FC-F9100 Crankset

The FC-R9100 enables optimal power transfer. This is achieved through its wider HOLLOWTECH II arm and a reinforced outer chainring on its unique asymmetrical four-arm spider design. In terms of stiffness and lightness, the new R9100 cranksets meet the highest demands.
