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 BH-Coloma Team, MMR Factory Racing, Orbea Factory Team or previously by road bike teams like Caja Rural Seguros RGA, Saxo Bank and Movistar.


The story goes like this: I had just bought my new wheels and a few days later I discovered that a new tubeless tire system had come onto the market. I thought it was brilliant idea which is what drove me to research the way to get rid of the tubes on my brand-new wheels.
When I started thinking about how to make tubular ready my own wheels, I had no idea what this would involve given I had been trained as a lawyer. I only knew that these new tubeless wheels carried a liquid inside, a different type of rim tape and together with the valve, this is what sealed the tires.
In the midst of my experimentation process, I saw a documentary on the elaborate make up process of Star Wars characters and that´s when I discovered latex. After lots of trials and combinations with latex and other components, I finally came upon the formula for an effective sealant. Here Sincameras (literally “without tubes” in Spanish) was born.

We are constantly working on improving our formula, year after year, and we have broadened our range of products to include wax-based lubricants, more ecological than oil therefore contributing to lowering the impact on our environment, cleaners, rim tape for making tires tubular-ready, valves and other accessories.
What started as a hobby in order to convert my newly bought MTB wheels to tubeless, has ended, not only with new tubeless wheels for my bike, but also a passion that has become my profession.
