Elevate your biking experience with this high-performance oversized pulley wheel system, an essential upgrade for any dedicated bike racer or biking enthusiast. This premium two-wheeler component is constructed with a high-strength, exceptionally-lightweight carbon fiber derailleur cage that provides exceptional rigidity without adding unnecessary weight. The pulley wheels themselves are made from hard-wearing POM (Polyoxymethylene), a material known for its low friction wear resistance, and self-lubricating properties, ensuring a longer service life compared to standard alloy pulleys
As a drivetrain part, this system is designed to provide a significant performance boost. The oversized 13T upper and 17T lower pulley wheels the angle of the chain as it runs through the derailleur, which drastically cuts down on friction. This translates to smoother, crisper gear change and a more efficient transfer of power from your legs to the road.
