Construction and Materials

These roller weights feature a low-friction coating that helps prevent flat-spotting, ensuring consistent shifting during operation. Made from heat-resistant polymer, they retain their shape even in high-temperature environments typical of variator systems. This construction improves performance longevity and reliability.
