Discover real power with InfoCrank®

What does the InfoCrank measure?

The InfoCrank® has been developed for the cyclist who wants accurate and real power meter readings.  

A cyclist’s power comes from the amount of Tangential Force or Torque applied through the cranks.  The InfoCrank® only measures this force and ignores other force loads which, whilst being present, don’t benefit the cyclist’s power output.

The InfoCrank® uses a Wheatstone Bridge to measure Tangential Force.  This means there is no calibration necessary, there’s no re-zeroing and it operates accurately at any temperature, second by second, day by day and year by year.  It’s also fully waterproof.

What this means for the cyclist

As InfoCrank® only measures the Power Generating  force, the rider gets a genuine measure of the power generated.  

And because this measurement is accurate, throughout a ride and from day to day, it is possible to track performance gains with complete confidence.  

InfoCrank® only measures Torque
1. Tangential Force

A cyclist generates power by applying Tangential Force, or Torque, to the cranks.  This is the only force the InfoCrank® measures, in both the Left and Right Crank, giving you impressively accurate power readings (0.06% error at 3000W as measured by British Cycling).

2. Axial Load

Axial Load produces tension or compression in the crank arm. It is highest when the rider’s weight acts downward on the pedal when the pedal is at its lowest point.

3. Side Load

 Side Load can be present when the rider leans the bike during hard acceleration.

4. Pedal Axis Torque

 It is not possible to apply Pedal Axis Torque to the crank through the pedal unless the pedal bearings are faulty.

5. Crank Axis Torque

Crank Axis Torque is always present since the pedal centreline is necessarily offset from the crank.

6. Side Torque

Side Torque bends the crank towards or away from the frame. This load is highest when the rider’s weight acts downward on the pedal when the pedal is at its lowest point.
