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 pulleysAs 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. Imagine tackling a steep climb or sprinting for the finish line with less resistance holding you back. The CNC-machined precision and high-quality bearings in the rear derailleur guide wheels ensure every rotation is silky smooth, saving precious watts with every pedal stroke.Before purchasing, it is crucial to the compatibility with your specific rear derailleur model. This system is designed to integrate seamlessly with a variety of popular bike component brand and drivetrain component groupsets, but selecting the model is key to achieving a optimal installation and optimal performance.
