The brand new non-circular crowns compatible with most cranksets on the market.
Designed with the same profile as the original Osymetric, with teeth with different thickness
Made in Italy
N-C Power crowns have been designed to transmit the greatest amount of energy from the legs to the pedals
Non-circular design conforming to Osymetric's patent
For example, our 34d non-circular crown is equivalent to a continuous variator from 30d pel point of maximum effort to a 38d in the lower dead center where the speed rotation is greater than with round crowns
Overcoming the impossible climbs for round crowns, producing greater acceleration and the higher top speeds you can!
