Features:
- The evolution of the exclusive Sunstar Works-Z sprocket, now made from the highest quality stainless steel.
- Weighs up to 50% lighter than standard steel sprockets.
- Offset tooth design allows the sprocket to be 50% thinner than a traditional 520 steel sprocket making it the lightest STEEL sprocket available on the market.
- 100% heat treated AND even lighter than before with new weight reduction hole cut outs, but still has a hardness 5 times that of an aluminum sprocket and twice that of a standard steel sprocket.
- Up to 4 TIMES more durable with 1.2 times the lateral strength of any aluminum sprocket.
- Great self cleaning capabilities due to the alternating offset tooth design, same as the original Works-Z sprocket which extends the life of the entire chain drive system.
