Stans notubes products

Their Story:

It all started in 2001, when a rider named Stan Koziatek had an idea. Frustrated with punctured inner tubes and believing that mountain bike tires could perform better without them, Stan developed a way to replace the inner tubes with a liquid sealant. Stan's system created a tire that sealed almost instantly when punctured, but that was just the beginning. Without an inner tube, tires treated with Stan's sealant offered more traction, more control, and more comfort. They also rolled faster. The performance advantages were tremendous, and soon riders at the highest levels of the sport were asking Stan to help them go tubeless.

Stan's ability to solve problems and create innovative solutions was matched by co-founder Cindy Koziatek's drive to grow the business and commercialize those innovations.

It was Cindy who realized the company needed a website to help reach new customers and explain tubeless technology to more users. At races and online, Stan and Cindy's efforts to introduce the concept to more people helped establish modern tubeless systems.

Today, cyclists and racers around the world rely on the tubeless technology developed by Stan, and our sealant has been recognized as one of the most important innovations in cycling history. For us, “The First Name in Tubeless” is more than just marketing. It's who we are.

Everything we learned about sealing conventional rims for tubeless use led us to develop our own line of rims and wheelsets. With our patented Bead Socket technology, our rims and complete wheelsets are considered the easiest and most reliable to manufacture.

For over a decade, our products have set entirely new performance standards, created entirely new categories, and redefined what others thought was possible. Our Dual Action Tubeless Repair Tool (DART) offers a whole new level of tubeless repair for mountain, road, and gravel bikes. The DART is a quick and easy puncture repair insert that seals even large punctures and rim cuts by physically filling the puncture while also reacting to Stan's tubeless sealant, creating a near-instant airtight seal. Unlike conventional plug tools, the DART requires no trimming and can be mounted instantly without interfering with tire performance and feel, even on soft road tires. Our line of ultralight, high-performance carbon rims and wheelsets was designed based on the insights we learned from tubeless tires. To create a better carbon rim, we developed our Radial Impact Absorbing Carbon Technology (RiACT), a special rim shape and manufacturing process that absorbs vibration radially while remaining incredibly stiff laterally to resist torsional forces and improve handling.

We also continue to drive the development of high-performance tubeless systems for road bikes, offering carbon fiber and aluminum rims specially designed to withstand the higher pressures of tubeless road tires.

Our latest asymmetric rim designs took years to develop and bring Stan's legendary ease of inflation and reliability to offset rims that allow for stronger overall wheel builds and, in most cases, a single spoke length for both front and rear wheels. By focusing on details like this, we continue to improve tubeless performance for all cyclists.

With nearly eighteen years of constant evolution, Stan’s Sealant continues to distance itself further and further from imitators. In 2016, we also introduced a second formula, capable of sealing even larger punctures. Innovation will always be the driving force behind Stan’s NoTubes. Why? Because we ride bikes. We ride bikes to test our designs, refine them, and then test them some more. But mostly, we ride bikes for ideas. Every innovative product we’ve created started as an idea we had while out for a ride. There’s something about cycling that makes you want to go even further next time, even faster. There’s something about cycling that pushes you to the limit. That’s our inspiration. By constantly looking ahead, beyond those limits, we continue to build truly revolutionary products—products that aren't just a little better in one or two categories, but raise the bar in every way. Our wheelsets and tubeless systems are lighter and, at the same time, more reliable. They grip better for greater control while rolling faster to help you push your limits. For us, true innovation means always looking beyond limitations. That's how we develop our products, and that's why we ride.
