About this Product
The CZ 219 O-Ring ORS Black Box chain is an ultra-reinforced version of the RS chain, developed specifically for endurance racing and high-intensity applications. Featuring CZ’s proprietary O-Ring technology, this chain offers exceptional durability, reduced wear, and lower maintenance requirements.
The O-Ring design helps to retain lubrication, significantly reducing chain stretch and increasing its lifespan compared to the standard RS chain. This makes it perfect for longer races, such as endurance events and championships, where reliability is crucial. While it has slightly more friction than the RS version, the trade-off in durability makes it the ideal choice for drivers prioritising longevity over minimal resistance.
Like the RS version, the Black Box ORS chain is a multiple European and World Champion winner and is increasingly chosen by top-tier Racing Teams, including several Factory Teams. Its superior reinforcement makes it the ultimate choice for intense racing conditions, offering unmatched reliability and performance over the Blue Box O-Ring chain.
