Revolutionize your training with the Rotor 2INpower! This dual-sided power meter with integrated power measurement in the axle and right crank arm will enhance your training in both quality and experience. This crankset is based on the well-known INpower watt measurement system. The 2INpower measures power individually from each leg, providing accurate data on balance, performance, and potential improvements in pedaling efficiency. The power measurement of the left leg is typically measured using two pairs of strain gauges in the axle. These strain gauges are arranged oppositely, eliminating the need for recalibration during temperature fluctuations. Two additional pairs of strain gauges are placed in the right crank arm, measuring only the power of the right leg. This allows for independent or combined pedal analyses using Optimum Chainring Angle (OCA) and Torque360 metrics with the free user software.
