Constructed from high-quality 1045 high-carbon steel, this SUNSTAR rear sprocket is engineered for durability and performance. The material is heat treated to enhance overall strength and improve wear resistance, ensuring reliable operation under demanding riding conditions. To optimize the component’s mass, computer-designed weight reduction holes are incorporated into the design wherever structurally feasible.
Surface protection is prioritized to extend the service life of the sprocket in various environments. Most units feature a zinc plating finish, while others utilize a baked-on durable paint process. These corrosion-resistant treatments help maintain the integrity of the steel against environmental factors, providing a robust solution for drivetrain maintenance and upgrades.
