AUTOFOCUS MECHANISM
When the force is applied to the pedal, the chain moves outward. You feel the ring increases the diameter as the chain runs higher on the ring. As amount of moving will fluctuate by the force applied, it maximizes the benefits of non-circular ring, and assists your pedal stroke to remain efficient.
*there is no need of pedal stroke analysis to identify peak point or adjustment of mounting position.
