The Sunstar Works Z Rear Sprocket represents the evolution of the exclusive Works-Z design, constructed from high-quality stainless steel to deliver superior performance characteristics. This component features an offset tooth design that reduces thickness by 50% compared to traditional 520 steel sprockets, resulting in a weight reduction of up to 50% over standard steel alternatives. The inclusion of new weight reduction hole cut-outs further optimizes mass without compromising structural integrity, establishing this as the lightest steel sprocket available on the market.
Durability and longevity are enhanced through a 100% heat-treated process that achieves a hardness five times that of aluminum and twice that of standard steel. The sprocket offers up to four times the durability of comparable components, with lateral strength 1.2 times greater than any aluminum sprocket. Additionally, the alternating offset tooth design provides self-cleaning capabilities that help extend the operational life of the entire chain drive system.
