Our first integrated power meter ensures extremely high data accuracy. The FC-R9100-P is Shimano's first power meter and the first crank-integrated power meter on the market. It retains the unique asymmetrical spider design with four arms, but with a "brain" inside. The strain gauges are located on the crank arm. These work together in perfect synchronization, allowing you to improve your performance with highly accurate data.
