The fact that a performance measurement system for systematic training is almost indispensable and provides numerous advantages over the training control over the pulse, should have spoken among cyclists already around. The ever-increasing demand for performance measurement systems, Shimano has developed the Dura-Ace FC-R9100-P a power meter that fits optically perfect in the current Dura-Ace 9100 Top Group. Despite its compact, discreet design, it has all the features you could want from a power meter. Also on the scales fall of integrated power meter negligible. Compared to the standard Dura-Ace 9100 Crank the PowerMeter version weighs 60-70g more.
The brain of the power meter is integrated into the Spider of Shimano's current FC-R9100 aluminum handle. With its hollow, extra wide Hollowtech 2 crank arms, it is distinguished by its extremely high stiffness at low weight. The performance is measured by strain gauges in two crank arms. Dehalb this system enables accurate impact analysis. Force discrepancies between the legs can be detected after a workout and even while driving. With a maximum measuring error of +/- 2% is Shimano's power meter at par with the top dogs on the market. The battery is integrated into the crankshaft and is charged through a small magnetic adapter. This supports the clean look of the power meter. By eliminating the USB port the sensitive electronics is sealed and the system is therefore completely waterproof. Dirt, splash and Hochdruckreniger are therefore no problem for the power meter.
