This complete kit (sprocket, crown, chain) combines a gold-plated 520M3 chain and an ultra-light aluminum sprocket to reduce unsprung mass without sacrificing tensile strength and abrasion resistance. Gold/Gold finish for a polished racing look and better protection against corrosion in muddy conditions.
