ROTOR 2InPower Power Meter Crank

$ 1.500,00

The Rotor 2Inpower Power Meter is here to show you the way into the realm of accurate and precise power measurement. The dual-sided 2Inpower meter measures power individually from each leg to provide precise data about balance and power output allowing you to see where you can make improvements to your pedaling performance. The Rotor 2Inpower is the evolved form of the Inpower, which is a power meter integrated inside the crank axle and measures the power from the left leg. To achieve power measurements from both legs, the 2Inpower features 2 additional sets of strain gauges that have been placed on the right crank arm to measure exclusively from the right, allowing for complete and accurate power measurement.
