Specifically designed for racing and intense training on road bikes, the new Smartube RS sets new standards in terms of speed, weight, and puncture protection. Thanks to a completely revised formula, it is up to 26.5% faster than its predecessor and even lighter—without compromising reliability. Whether used with classic wire tires or tubeless-ready setups, the Smartube RS integrates seamlessly and offers maximum versatility for all road enthusiasts. Its outstanding rolling characteristics have been proven in independent tests, reaching the level of modern tubeless systems—without their typical drawbacks such as sealant, dirt, or complicated maintenance. Available with a Presta valve in three different lengths: 42 mm, 60 mm, and 80 mm.
