The Silca Secret Chain Blend brings professional, World-Championship-level speed and silence straight to your drivetrain. Composed of highly refined, laboratory-grade paraffin wax and heavily infused with three distinct sizes of nano-scale Tungsten Disulfide (WS2), this hot wax treatment doesn't just coat your chain—it actively modifies its surface at a molecular level, filling microscopic imperfections to dramatically lower friction and wear.
Watt Savings & Efficiency: Saves up to 8 watts of power by reducing dynamic friction significantly below standard PTFE or Molybdenum formulations.
Extended Component Lifespan: Keeps your drivetrain exceptionally clean and protected, extending the life of your chain and cassette up to 10x (up to 25,000 km).
Submersible Pouch Application: Packaged in a heat-resistant, sous-vide style pouch. You can melt the wax by submerging the bag directly in hot water on your stovetop—no dedicated crockpot required.
Environmentally Friendly: 100% free from harmful PFAS chemicals.
Seamless Compatibility: Works perfectly as a system with Silca Super Secret Drip Lube for quick, mid-interval top-offs without removing the chain.
Weight: 500g (17.6 oz) pouch
Interval: Re-wax or top-off approximately every 300 to 500 km (depending on riding conditions).
Compatibility: All modern bicycle chains (Road, Gravel, MTB, E-bike).
