Stan's NoTubes bicycle wheelsets and tire sealants

Stan's NoTubes is a pioneering brand in the cycling industry, credited with revolutionizing the tubeless tire movement. Founded by Stan Koziatek, the brand initially gained fame for its liquid tire sealant, which allowed mountain bikers to ride without inner tubes, reducing weight and improving performance. Today, the brand is a global leader in high-performance mountain bike and gravel wheels.

In early 2024, Stan's NoTubes was acquired by the British cycling group Upgrade Bikes Ltd. This acquisition secured the brand's future and transitioned its headquarter operations to the United Kingdom. While the brand remains deeply rooted in its American heritage through its research and development history, the current manufacturing and distribution networks span across the UK, Taiwan for rim production, and the USA for specific assembly needs.
