Extremely light, extremely robust: the inner tube revolution from Aerothan.
Aerothan is a material that completely redefines the bicycle inner tube: extremely light, high-quality puncture protection, and low rolling resistance.
The revolutionary Aerothan inner tube has unparalleled properties in elasticity, weight, and puncture resistance.
Specifically designed for road bikes, mountain bikes, and trekking bikes – all without butyl.
Aerothan Tube - The facts
· Consistently light right up to the valve – about 40% lighter than a comparable Schwalbe Extralight inner tube
· The new definition of puncture resistance – the new material prevents sudden air loss
· Minimal rolling resistance – maximum riding dynamics
· 100% recyclable
· Extremely heat resistant – approved for rim brakes
· Stable riding characteristics – even at low tire pressure
· Made in Germany

Spectacular and innovative: With the Aerothan tube, a new era in inner tube technology begins, completely without rubber!
Unique in its kind, light & extremely stable:
The inner tube revolution made from Aerothan
The revolutionary new inner tube from Schwalbe made of Aerothan achieves unprecedented top values in elasticity, weight, and puncture resistance – all without rubber. For road bikes, mountain bikes, and trekking bikes.
100 grams less weight on the road bike, puncture resistance for extreme touring cyclists, or tire pressure around one bar on a mountain bike without increasing the risk of flats: what sounds tempting is now reality thanks to the new thermoplastic polyurethane called Aerothan.
With the Aerothan tube, cyclists and tour riders can push the limits of their capabilities further than ever before. Aerothan tubes are much more robust and resistant than butyl, latex, or other plastic inner tubes.
The transparent Aerothan tube, weighing only 41 grams, is innovative through and through: “For more than five years, we have perfected the material in collaboration with BASF down to the smallest detail and made groundbreaking improvements. This is the only way we could combine the apparent contradictions of minimal weight and maximum puncture resistance,” says Felix Schäfermeier, Schwalbe Product Manager. “The result exceeds all our expectations!” The material, a thermoplastic polyester-polyurethane, impresses with its excellent physical properties: high resilience, unique tensile strength, excellent damping, extreme heat resistance, and maximum abrasion resistance. And of course, the Aerothan tubes are also recyclable.
Aerothan tube: The new benchmark for low weight and puncture resistance
The effects of these properties in the Aerothan Tube are impressively demonstrated by comparison tests with other models. The plunger test simulates the penetration of a small object, such as gravel. This is exactly what causes many punctures in practice. Here, Aerothan lasts twice as long as other materials: 47 Newtons are required to pierce the Aerothan tube – more than twice as much as with other materials. Even in the snakebite test with a guillotine, Schwalbe’s new inner tube can withstand significantly greater drop heights than butyl, latex, or other plastic inner tubes. Its heat resistance is also excellent: it has been tested at temperatures over 150 °C at 78 km/h in a specially developed process.
When it comes to weight, Aerothan scores with its low weight, from 41 grams for road bikes to 61 grams for allround riders to 81 grams for MTB. In rolling resistance tests, the results match traditionally fast latex inner tubes and tubeless systems.
The exceptional dimensional stability of the material offers even more advantages. Aerothan inner tubes do not burst suddenly; instead, the air escapes slowly in case of damage. Even at extremely low air pressure, the shape and riding stability remain stable – reducing the chance of flats or burping. And: mounting is much easier: the inner tube does not slip and cannot get pinched.
Unparalleled riding experience
“Despite the high surface tension, the reset property is excellent and provides a soft yet dynamic and precise riding experience that I have never experienced before,” says Felix Schäfermeier, a former professional racer himself, about the unparalleled riding experience. The inner tube fits so smoothly and snugly onto the tire, as if it were part of it.
Like all Schwalbe products, the new inner tube was not only made in the lab but also perfected through thousands of test rides. Professional racers, triathletes, World Cup mountain bikers, and world cyclists provided valuable feedback for the developers.
Including Patrick Lange, Ironman Hawaii World Champion 2017 and 2018. His conclusion: “Aerothan is my first choice. On the one hand, because you can save 100 grams per set of tires compared to conventional inner tubes. On the other hand, I am excited about the lower rolling resistance: the difference is especially noticeable when accelerating.”
