The JT Sprockets JTA486.42BLK sprocket is a drive component designed for the replacement or modification of the gearing on roadsters equipped with a 520 pitch chain. Made from aerospace-grade 7075‑T6 aluminum (Ergal), it offers an ultra-light option to reduce the final drive weight without changing the mounting type.
This sprocket is suitable for riders looking for a reliable replacement for a worn part or a gearing change to adjust their road behavior. Its Ergal design ensures a good balance between lightweight and mechanical strength while maintaining the standard dimensions required for mounting on hubs designed for a 520 sprocket.
Common compatibilities (examples):
Always check the number of teeth, chain pitch, and hub pattern before ordering to ensure compatibility and hassle-free installation.
