UNIQUE IN ITS KIND, LIGHTWEIGHT & EXTREMELY STABLE: THE INNER TUBE REVOLUTION MADE FROM AEROTHAN

Schwalbe's revolutionary new Aerothan inner tube achieves unprecedented top values ​​in elasticity, weight, and puncture resistance—and does it entirely without rubber. For road bikes, mountain bikes, and trekking bikes.

100 grams lighter on a road bike, puncture resistance for extreme touring cyclists, or tire pressure around a bar on a mountain bike without increasing the risk of punctures: what sounds tempting is now a reality thanks to the new thermoplastic polyurethane called Aerothan. With the Aerothan tube, cyclists and touring riders can push the boundaries of their capabilities further than ever before. Aerothan tubes are much more robust and durable than butyl, latex, or other plastic inner tubes.

The transparent Arothan tubular tire, weighing just 41 grams, is thoroughly innovative: "For over five years, we've been perfecting the material down to the smallest detail in collaboration with BASF, making groundbreaking improvements. This is the only way we could combine the apparent contradictions of minimal weight and maximum puncture protection," says Felix Schäfermeier, Schwalbe Product Manager.

The result exceeds all our expectations! The material, a thermoplastic polyester-polyurethane, impresses with its outstanding 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 light 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 granulate. This is precisely what causes many punctures in practice. Here, Aerothan lasts twice as long as other materials: 47 Newtons are required to penetrate the Aerothan tube – more than twice as much as with other materials. Even in the snakebite test with a guillotine, the new Schwalbe inner tube can withstand significantly greater drop heights than butyl, latex, or other plastic inner tubes. Its heat resistance is also excellent: it was tested at temperatures of over 150°C at 78 km/h in a specially developed process.

When it comes to weight, Aerothan scores with its low weight, ranging from 41 grams for road bikes to 61 grams for all-around riders and 81 grams for MTBs. In the rolling resistance test, the results are consistent with traditional fast latex inner tubes and tubeless systems.

The material's exceptional dimensional stability offers even more advantages. Aerothan tubes don't burst suddenly, but the air escapes slowly in the event of a defect. Even at extremely low air pressure, the shape and stability of the tire remain stable. This reduces the risk of punctures or burping. And: installation is much easier: the tube doesn't slip or become pinched.

Unparalleled driving experience

"Despite the high surface tension, the resetting properties are excellent, providing a soft yet dynamic and precise riding experience I've never experienced before," says Felix Schäfermeier, a former professional cyclist himself, about the incomparable riding experience. The inner tube fits so smoothly and snugly against the tire, as if it were part of it.

Like all Schwalbe products, the new inner tube wasn't just created in the lab, but also perfected through thousands of test rides. Professional cyclists, triathletes, World Championship mountain bikers, and world cyclists provided valuable feedback to the developers.

Including Patrick Lange, Ironman Hawaii World Champion 2017 and 2018. His conclusion: Aerothan is my first choice. Firstly, because compared to conventional inner tubes, it can save 100 grams per set of tires.
