Silca EnduranceChip Description: Silca Hot Melt Wax Additives help craft hot melt wax formulas that in turn improve the qualities of wax melt formulas, allowing riders to craft a blend that perfectly matches their needs. Silca crafted their podium-winning Secret Chain Blend Wax utilizing 4 different types of wax for a result that set the standard for chain wax performance in the industry. In a move to provide blends that better suit the needs of all riders, Silca offers wax customization in the form of SpeedChip and EnduranceChip, two distinct wax additives that aim to further tune the properties of chain wax to perfectly suit rider needs.
