Revolutionize your training with the Rotor 2INpower! This dual-sided power meter with integrated power measurement in the axle and the right crank arm enhances the quality and experience of your workouts. 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 done in the typical INpower manner using two pairs of strain gauges in the axle, arranged in opposite directions, so recalibration due to temperature fluctuations is unnecessary. 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 the Optimum Chainring Angle (OCA) and Torque360 metrics with the free user software.
