The Pedal Center Offset 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 also known as Platform Center Offset
