#Silca Super Secret Chain Coating can be used alone (after a thorough chain stripping) or, our favorite method, to extend the life of a hot waxed chain between applications. Apply one drop per roller and let it dry overnight. This top off will keep you rolling for another 200km or more. Important Note: Never apply immediately before a ride! The wax carrier needs time to evaporate for optimal performance. When to top off? Listen for it! Chains typically start to "chirp" or squeak at the beginning of wear. Noisy waxed chains are still better than oil based lubes at protecting against wear. Where as oil based lubes have no real indicators when they need to be re-applied.
