Description

Shimano's R9100 series crankset achieves the ultimate in optimal power transfer. It does this through its broader Hollowtech II arm and a more reinforced outer chainring on its unique asymmetrical four-arm spider construction. The R9100 cranks set the highest standards for stiffness and lightness. With the first integrated power meter, you can expect extremely accurate data. The FC-R9100-P is Shimano’s first power meter, as well as Shimano’s first crank-integrated power meter on the market. It retains its unique asymmetrical four-arm spider construction, but with a ‘brain’ mounted on the inside. On its crank arm are the strain gauges. Working perfectly in sync with each other, you can use the extremely precise power data to improve your performance.
