• Silver anodized finish — electrically coated to resist corrosion and provide a bright, clean appearance
• Patented unique tooth design — increases sprocket longevity and promotes smooth chain engagement
• Cupped body profile — material is relieved from the tooth ring inward to shed as much weight as possible without sacrificing strength
