The brand new non-circular crowns compatible with most cranksets on the market.

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!

Profile with wide and narrow teeth to prevent the chain from falling in accordance with the expired patent US 4,174,642

Compatible with FRMcranksets, Sram XX1 (BCD 76mm), X01, X1 (BCD 94mm) or cranksets BCD 104mm, with 10, 11 and 12 sprocket transmissions

The chain guide is not necessary but recommended anyway
