The InfoCrank was developed for cyclists who want precise and real performance data - directly on the bike and for later analysis.
Cycling power is generated by the tangential force or torque acting on the pedal crank. The InfoCrank only measures this force and no other forces. Because only the tangential force drives the wheel. The InfoCrank measures the force directly. It is not derived or calculated. Therefore, the InfoCrank needs no zero offset, no smoothing and works reliably and accurately at any temperature, at any altitude and is also absolutely waterproof.
The InfoCrank Professional comes in a bundle with matching bottom bracket and chainrings. You only need the crank? You can find it here!
