Prolink Chain Lube is a chain lube and cleaner in one! It dramatically extends the life of your chain and works in wet and dry conditions, keeping your chain and drive train clean and seamlessly drag-free. The thin-bodied lubricant greatly reduces friction and wear with friction reducer technology for smoother shifting and a quiet drive train. Does not build up or become tacky; sheds dirt, mud, and abrasives. Also repels moisture and prevents corrosion.
