PBR Ultra-Light Hard Anodized Aluminum Sprocket 4684 - 525

Born from PBR's competition experience, this lightweight aluminum sprocket is designed for the final drive of roadsters and sport machines. Made from high-quality aluminum and treated with hard anodization, it combines lightness and strength for demanding road use.
