Osymetric for the road
There are 56 products.

Osymetric for the road has been designed so that the radius of the chainring varies in proportion to the force produced by the leg from top dead center to bottom dead center.
In fact: at top dead center the leg is twice weaker than when the crank is horizontal, which implies a slowing down of the angular speed at top dead center which produces asphyxiation of the muscles, in particular the vastus lateralis due to resistance torque too strong for the leg, and not a recovery zone as is commonly accepted.

The objective of the geometry of the Osymetric road chainring has been to make it easier to work where the leg is weak (top dead center and bottom dead center which implies a small radius) and to provide work where the leg is strong.


With Osymetric for the road, the legs pass through dead points more quickly, which are therefore relatively less "dead": therefore more efficient.
