X-Sauce (formerly Sincamaras) was founded in 2001 when the idea of building ones own tubeless bike wheels without special rims and tires, started to become popular. Trials and tests where many and long until September 2003 we decided to do a modest soft launch of the product to the market during the Festibike in San Lorenzo de El Escorial (Madrid). We have now lost track of how many tubeless kits and bottles of anti-puncture sealant are circulating within our national borders. Our half liter bottle of anti-puncture sealant is our best-selling product as well as the dismountable UST compatible valves. Our products are used by professional mountain bike teams like Primaflor – Mondraker – X-Sauce or previously by road bike teams like Caja Rural Seguros RGA, Saxo Bank and Movistar.
