The shape of O.Symetric chainrings makes pedaling harmonic and more efficient. Performance increase of +10%, better acceleration and reduce lactic acid production of the muscle to -10%.
When a biker uses classical shaped chainrings, effort changes in different crank positions. The non-circular shape of the O.Symetric chainrings brings effort in balance and allows a "more rounded pedaling" for increased efficiency and performance. O.Symetric chainrings are used by professional bikers in several disciplines.
