EnduranceChip is the best option for ultra-endurance events or training chains to get the most longevity out of your components. EnduranceChip is a semi-synthetic wax blend boasting some of the longest molecular chain lengths possible in a wax for ultimate durability. Adding EnduranceChip to SecretBlend can permanent increase the distance between re-waxing by as much as 2.5X (up to 750km) while still being as fast as the top wet lubricants and significantly faster than any dry lubricant. Add a second chip for even further single application longevity. 1 EnduranceChip/250g increases longevity up to 550k 2 EnduranceChip/250g increases longevity up to 750k Compatible with StripChip Silca Endurance Chip Wax Additive Lubricant UPC: 810093162840
