LENGTH: 112 links with rivet joint (ZJ) It uses X-Ring technology, the best technology available for transmission chains. The lubricating grease is in fact retained by torsion and not crushing, resulting in a lower drag resistance or greater smoothness and less dispersion of power (more horsepower and less fuel consumption), and a longer duration of the chain over time. The chain must in any case be cleaned and lubricated at regular intervals using only specific detergents and lubricants. Chain developed for super-powerful road bikes, with very high operating loads and torque. The use of new materials and sophisticated heat treatments of the external plates make this type of chain more resistant to wear, ensuring about 30% more than a professional O-Ring chain.
