Full synthetic, ester-fortified bicycle chain lubricant formulated specifically to be used in wet and rainy conditions. Advanced, surface-active formulation penetrates deeply and tenaciously clings to the chain, minimizing fling-off while keeping water, mud and grime from contacting chain components. Proprietary anti-wear additives minimize chain noise, enable smooth shifts under load and extend chain life. Long-lasting, waterproof formulation protects over the longest rides without reapplication. E-Bike Approved.
