Rotor InPower 3D+ MAS Full Crankset

Modern cyclists who are serious about their progress will require an accurate and reliable power meter. Rotor has designed an axle based power meter system, which is fully enclosed inside the crank spindle within the frame. This protects the power meter from the weather, temperature changes and shock.

This system was designed to provide the most consistent and reliable power readings across all disciplines and when used with multiple frame designs. As the power meter is centralised to the bottom bracket shell, it enabled this continuity to become reality.

Conveniently this system requires just one AA battery to function, which provides over 300 hours of battery life. The same as riding the three Grand Tours back to back

The large oversized 30mm axle that houses the power meter is compatible with the majority of frame designs thanks to Rotors modern bottom bracket options. The advancement of this power meter enables the measuring of your torque output (Torque 360) and also your Optimum Chainring Angle (OCA), which is the physical force you are applying to the pedals.

Created in unison with the design of this crankset is the INpower software, which collects the data that you have created when using the power meter. The software is free and will transform your training and performance output.
