Schwalbe SV17E Aerothan 37/50-622 IB 60mm inner tube

UNIQUE OF ITS KIND, LIGHT & EXTREMELY STABLE: THE INNER TUBE REVOLUTION MADE OF AEROTHAN. The revolutionary new inner tube from Schwalbe made of Aerothan achieves unprecedented top values ​​in terms of elasticity, weight, and puncture resistance – and does so entirely without rubber. For road bikes, MTBs, and trekking bikes. 100 grams less weight on the 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 reality thanks to the new thermoplastic polyurethane called Aerothan. With the Aerothan tube, cyclists and touring riders can push the limits of their capabilities further than ever. Aerothan tubes are much more robust and resistant than butyl, latex, or other plastic inner tubes. The transparent Aerothan tube, weighing just 41 grams, is innovative through and through: “For more than five years, we have perfected the material down to the smallest detail in collaboration with BASF 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 wear resistance. And of course, 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 granules. This is exactly what causes many punctures in practice. Here, Aerothan holds up twice as long as other materials: 47 Newtons are required to puncture 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 exceeding 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-round riders to 81 grams for MTB. In the rolling resistance test, the results match those of traditionally fast latex inner tubes and tubeless systems. The material's extraordinary dimensional stability offers even more advantages. Aerothan inner tubes do not burst suddenly; instead, air escapes slowly in the event of a defect. Even with extremely low air pressure, the shape and riding stability remain stable. This reduces the likelihood of punctures or burping. And: installation is much simpler: the inner tube does not slip and cannot get pinched. Incomparable riding experience "Despite the high surface tension, the reset property is excellent and ensures a smooth yet dynamic and precise riding experience that I have never experienced before," says Felix Schäfermeier, a former professional cyclist himself, about the incomparable 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 created in the laboratory but also perfected through thousands of test rides. Pro 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. On the one hand, because 100 grams per set of tires can be saved compared to conventional inner tubes. On the other hand, I am enthusiastic about the lower rolling resistance: the difference is particularly noticeable when accelerating. Properties :
