• Vortex patented tooth design — unique profile maximizes sprocket longevity and chain engagement
• Hardened teeth — maintain structural integrity over thousands of miles without loss of strength
• Cupped body design — material removed between the tooth ring and sprocket body to minimize weight wherever possible
