ThreeD 520 GP Chain Black 120 Links 520GP3D-120KG

Precise Forging process leads to a stiff chain for better acceleration and more efficient engine work, Lightening hole allows for a lighter chain without compromising strength while removing mud and dispersing heat more efficiently, Improvement in transmission efficiency, Special pin with holes in both ends allow the chain to be lightened, Edge-cut inner plate reduces friction and allows for smooth engagement with sprocket, Chromium Carbide pin surface coating increases hardness and reduces chain wear
