The PCO measurement is calculated by identifying how force is distributed across the pedal platform during the pedal stroke. That means you can view and evaluate where force is applied relative to the center of the pedal platform and what the PCO distribution is over a given period of time. Analyzing this data can help you determine proper bike fit and cleat position. It may also be helpful in preventing injury and rehabilitation.

PCO is measured in millimeters. Positive values (e.g., +6 mm) indicate increased force toward the outside of the pedal, while negative values (e.g., -4 mm) indicate increased force toward the inside of the pedal. You can view this information in graph form on your Edge device. The red line indicates the current 10-second average value and the blue line represents the average for the previous 30 seconds.
