    Product description


    The Rotor 2INpower crank-based power meter offers ambitious athletes and pros a dual-sided power measurement thanks to a combined strain gauge system in crank axle and right crank arm. Four strain gauges placed in the right crank arm and four in the crank axle independently measure left and right side power, analyse the values and transmit all data on power, cadence, balance, torque efficiency and pedal smoothness to the end device. The data can either be transferred to a smartphone with a respective cycling app via SmartBluetooth (update required) or to a bike computer via ANT+. Besides, the 2IN power power meter comes with a special analysis software that can even help you find the perfect pedalling technique when used on a desktop computer or notebook (PC or Mac). Graphical tools like OCA (optimum chainring angle) and Torque 360 help you assess force variations in your pedal stroke. Based on a power analysis, the OCA system also helps you to find the perfect OCP set-up (optimum chainring position) of oval Q-rings (not included).
