The more data, the better, and with the Rotor 2INpower SL Dual Sided 2x Power Meter Crankset, we can get accurately measured power from each leg individually. Designed for demanding cyclists, the 48/31t chainrings feature an aerodynamic design that optimizes airflow, while the optimized sprocket set provides quick and accurate shifting on any terrain. In addition to a power measurement accuracy of /- 1. 5%, we are provided with data including cadence, balance, torque effectiveness, and pedal smoothness, helping us measure our overall cycling performance.
