“Best performing non-circular chainring”
PowerOval® is the result of an optimization exercise carried out with our “torque-driven bicycle rider computer model”.
This mathematical model allows to identify a non-circular chainring configuration that:
– for the same joint load as with a round chainring, generates maximal crank power gain,
– for the same crankpower as with a round chainring, results in minimal peak-load on knee and hip joint.
