Silca Wax Additives—SpeedChip and EnduranceChip—bring pro-level drivetrain tuning into the hands of everyday riders and elite athletes alike, offering unprecedented control over wax performance. SpeedChip is the fastest lubricant additive Silca has ever produced, trusted by WorldTour powerhouse Visma Lease-a-Bike for time trials and one-day classics. It’s made from the same ultra-synthetic base oils found in Synergetic, enhanced with a mix of nanoscale and sub-micron Tungsten Disulfide platelets to further reduce friction and wear. When added to Silca’s Secret Chain Blend, SpeedChip can permanently improve drivetrain efficiency by up to 0.6%, giving racers a clear mechanical edge. The tradeoff? A shorter lubrication interval—ideal for high-stakes events where speed outweighs longevity.

For long-distance athletes and daily trainers, EnduranceChip is the go-to optimization tool. This semi-synthetic wax additive is engineered with some of the longest molecular chain structures ever used in cycling lubrication, delivering outstanding durability without compromising speed. When blended with Secret Blend, a single EnduranceChip can extend waxing intervals up to 550km, while two chips can stretch it to an incredible 750km—more than double standard longevity. Designed to work seamlessly with Silca’s multi-wax system, including StripChip for chain prep, these additives allow riders to fine-tune their wax formula for the perfect balance of speed, endurance, and efficiency. Whether you're chasing a Tour de France stage win, grinding through a 200-mile gravel race, or just want your training chain to go the distance, Silca’s Wax Optimization system delivers elite performance, customized to your ride.
