Silca Wax Additive - Endurance Chip 1 Piece Tires HEADSET Zero-Stack InternalSILCA EnduranceChip is the other half of the wax optimization system designed for riders who want fewer wax intervals without sacrificing efficiency. A single EnduranceChip added per 250g of Secret Chain Blend extends wax longevity to around 550km. Add a second chip and you can push that to 750km, making EnduranceChip the right choice for high volume training blocks, bikepacking, or ultra endurance events where stopping to re wax isn't an option.
