Rotor Inpower V3 R50/34D Crankset with potentiometer - 172.5

The Rotor Inpower V3 R50/34D potentiometer crankset is an easy-to-use power meter that can be paired with cycle computers, allowing you to measure and monitor your efforts and fitness progress. It is a light and precise set, which measures the power developed with the left leg. INpower technology measures the torque of the axle, and at the same time locates all the electronics inside, creating a reliable, protected and durable product that you don't have to worry about inclement weather, external agents and/or possible knocks. Its interchangeable battery, which is located together with the electronics inside the axle, positions the entire rotational mass of the power meter centred with respect to the crankset, eliminating negative inertias during pedalling.
