One of the secrets behind Secret Chain Blend is that it's a mix of four unique types of wax, not just paraffin like most other hot wax products. This blend of waxes, along with our proprietary WS2, has kept Secret Chain Blend on top of the ZeroFrictionCycling charts for the last three years. Many competitors have reformulated in an attempt to match it — none have succeeded.
The four-wax mix has allowed SILCA to achieve what we believe is the ideal balance of high performance, dirt resistance, and application longevity. However, as we’ve worked with professional gravel athletes, WorldTour teams, Olympic medalists, and others, we’ve received consistent requests for custom wax formulations tailored to specific events or conditions. Rather than producing endless variations, we began shipping two different wax additive kits in early 2024 to athletes and teams for testing and optimizing blends based on their specific needs.
The challenge in wax formulation is clear: the fastest, most exotic waxes typically don’t last long per application, while the most durable waxes are often not the fastest. Instead of compromising, we gave athletes the ability to tune their own wax, and the results have been incredible — more than 100 victories across the WorldTour, Lifetime Grand Prix, the Olympics, and beyond.
This new system puts wax optimization directly into the hands of the athlete.
Want a training wax that lasts 600 km between applications? You've got it.
Need a race wax that’s won multiple Tour de France stages? You’ve got it.
Chasing the fastest possible TT wax for your 40 km time trial? You've got that too.
Internally, we first called this system “Wax Doping”, but with so much involvement from elite athletes, we’ve refined the name to “Wax Optimization.” Introducing SpeedChip and EnduranceChip — wax optimization agents that let you blend the perfect wax for your performance goals.
EnduranceChip
EnduranceChip is a semi-synthetic wax blend featuring some of the longest molecular chain lengths available in any wax. This results in extreme durability. When added to Secret Chain Blend, EnduranceChip can increase the interval between waxing by up to 2.5× (up to 750 km), while still maintaining speed on par with top wet lubricants — and significantly outperforming any dry lubricant on the market.
