The Inpower Road crank arms from Rotor Bike Components are a highly advanced solution for cyclists who want to measure their performance accurately. These crank arms are equipped with innovative watt measurement technology that captures power unilaterally from the left leg. By using opposing strain gauges in the bottom bracket axle, they provide precise measurements for cadence, pedaling efficiency, as well as force and torque effectiveness. The high-quality measurement technology is fully integrated within the axle, which not only offers an appealing look but also ensures excellent protection against external influences. The crank requires no expensive maintenance or frequent battery changes, as a standard AA battery lasts for about 300 training hours. The quick battery replacement is made easy with a sealed battery compartment. These crank arms are ideal for road cyclists who value precise performance data and want to enhance their training efficiency.
