The original sealant formula, introduced 2.5 years ago, was engineered to optimize puncture repair by increasing the liquid latex's surface area for superior effectiveness. Professional racers appreciated its ease of use, as they often swapped tires depending on race conditions and could simply pour in new sealant without valve injection. However, casual riders raised two main issues: it dried out quickly when unused, and the longer strand carbon fiber content made injection challenging and messy if not managed properly.
Previously, the Natural Latex formula required a two-step method to maintain its liquid state for an extended period. This has been replaced by our new combination of natural and synthetic latex. SILCA Ultimate Sealant now offers a single-step application that lasts over six months while continuing to deliver reliable puncture protection on race day.
