Shimano Dura-Ace FC-R9100-P PowerMeter Crankset 11-Speed



The Shimano Dura-Ace Dual Sided FC-R9100-P Power Meter HollowTech II Road Crankset 11-Speed is Shimanos first pedaling power measurement product and also the first crank-integrated power meter on the market. It is built to provide riders with one of the most accurate systems of power measurement, utilizing technology from bikefitting.com, a Shimano-owned company specializing in highly advanced bike fitting and bike measuring instruments.

The power meter allows integration and easy installation (pairing) with third party display units to enable the most sophisticated and accurate level of performance measurement and anatomic analysis available today. Not only can the pure output of watts be measured, left and right legs can be measured separately, as well as cadence, giving you the truest measure of performance, isolated from external factors such as gradient, road surface and wind.
