Valve Length


Schwalbe tubes are designed & manufactured to retain air pressure considerably longer than their competitors. Not only is each individual tube inflated & inserted into a mould to ensure that there is even wall thickness & excellent air retention, they are also stored under pressure for 24hrs to test air retention. Valve length of 40mm for Standard version. Weight 190g.

Applicable Tyre Sizes:
  • 37-622 700 x 35C
  • 40-622 700 x 38C
  • 42-622 700 x 40C
  • 44-622 28 x 1.65
  • 47-622 28 x 1.75
  • 50-622 29 x 2


Aerothan is a material that completely redefines bicycle tubes: extremely light, with maximum puncture protection and designed for minimum rolling resistance.



During the development of Aerothan Tubes, we have explored new avenues right from the beginning. The result was a high-end alternative to conventional bicycle tubes. The next generation Aerothan tube sets new standards for weight, puncture protection, riding characteristics, easy installation and packing dimensions. Specifically made for road bikes, MTBs and all-round purposes.


  • Fully light-weight, right to the valve - about 40% less weight than a comparable Schwalbe extra light tube
  • Puncture protection newly defined - the material itself prevents sudden air loss
  • Minimal rolling resistance - maximum riding dynamics
  • Extremely heat resistant - certified for rim brakes
  • A stable ride - even with low air pressures
  • Easy installation - without slipping or pinching
  • Made in Germany
  • 100% recyclable


Aerothan tubes consist of 100% thermoplastic polyurethane (TPU), including the valve, and are therefore fully recyclable. Like all Schwalbe tubes, Aerothan tubes may be returned to Schwalbe at no cost using the tube recycling programme. The material of used tubes is recycled to make sealing or insulation material.



Schwalbe aims to offer the ideal product for every cyclist. In terms of high-end bicycle tubes, this is an exciting challenge. The engineers had to combine seemingly opposing features, lowest weight and highest puncture protection. This is a case for the Schwalbe innovation hub, where material compositions and construction principles are redesigned to make entirely new products. Developed in cooperation with BASF and with experts from the German plastic manufacturing industry, the Aerothan tube emerged to not only meet all the requirements of a high-end bicycle tube, but to exceed them.


Prior to market release of a Schwalbe innovation, we carry out numerous tests to assess its quality. The Aerothan test results speak for themselves.


Interview with Schwalbe product manager Felix Schäfermeier about the development of Aerothan tubes.

How did you come up with the idea of developing a bicycle tube without rubber?

Bicycle tubes are a huge challenge for developers because one needs to combine completely opposing features in one product. A tube must be light-weight, but also extremely stable. With a classic butyl tube, one can achieve great puncture protection and excellent air holding capacities, but realising low weight is the limiting factor. Exactly this is why we wanted to completely rethink tubes and have decided to search for alternative materials. In cooperation with BASF, we have developed a thermoplastic polyurethane (TPU), which suits extreme requirements: Aerothan.

What was the biggest challenge during developments?

TPU-plastics already have many different applications in industry, e.g. as sealing or insulation material. And the approach to use this material for tubes is not new. However, past attempts have had significant limitations. For example, tubes were not approved for use with rim brakes due to a lack of sufficient heat resistance. We wanted to change this and have come up with special testing procedures to be able to test various materials. A thermoplastic polyurethane has allowed us to create an entirely new material base.

Is Aerothan a completely new material?

Yes, absolutely! In cooperation with BASF, we were able to reinvent Aerothan from scratch. Not only did we redevelop the base material, but we also redesigned the entire manufacturing process. During this phase, we got to benefit enormously from the expertise of German companies within the plastics processing industry. Aerothan tubes are produced in Germany using a patented laser welding process. This particular technique allows high precision welding of the valve and tube. In addition, it allows production of extremely flat seams that, not only secure a perfect form fit with the tire carcass resulting in extremely smooth riding, but also play an important role for puncture protection. After all, seams are subject to extreme mechanical stress. The durability of the seam was proven in several tests.

How was this tested?

Aerothan was subject to various lab and field tests where it was compared to existing materials and systems. An important point on the specifications sheet was also thermal resistance when used with rim brakes. Here, we have developed a specific test design which simulates high speed downhill rides on mountain descents. Aerothan has achieved an absolutely unique feature and is more heat resistant than all comparable materials.

What about real applications? Can you already tell us who is riding the new tubes?

Aerothan tubes have already been tried out by riders from our Schwalbe athletics programme at various events over the past year. These include MTB races such as Cape Epic, the Enduro World Series and long distance triathlons. The former Ironman World Champion Patrick Lange is very excited to use Aerothan tubes. This does not mean that Aerothan tubes are only intended for competitive athletes. We have also received very positive feedback from cyclists riding around the globe and bike packers. These tubes are just perfect for travelling by bike, because they are super light and stable, yet they do not take up very much space in the luggage.

And what is the verdict about the riding feel?

Aerothan tubes have been tested especially by riders with high tubeless affinity. At first, they were very sceptical, but the overall feedback was positive, some of them were actually surprised about how well the tube performed. Therefore, riding characteristics of Aerothan tubes are on par with the reference – tubeless – when it comes to performance. Normal cyclists also detected an obvious difference to conventional systems. Not only measured test results, but also subjective and individual opinions about the feel are convincing.

Are Aerothan tubes also puncture resistant despite the low weight?

Aerothan tubes are actually much more robust and durable than butyl, latex and other synthetic tubes. During developments, we wanted to focus not only on how Aerothan tubes would resist wear and tear when cycling, but also how the material would respond in the worst case scenario. In case of Aerothan tubes, air does not suddenly escape following a puncture, but slowly. If the carcass is cut, the tube will maintain its shape and does not push itself out. For all these reasons, it is much easier to control the bike in case of a puncture and cyclists do not have to worry about sudden air loss.

New materials, especially plastics, raise the question about sustainability. Is Aerothan recyclable?

An Aerothan tube is 100% recyclable – this was very important to us right from the beginning. Just like all other Schwalbe tubes, Aerothan tubes may be returned to us via the tube recycling programme. As opposed to conventional butyl tubes, Aerothan tubes are completely made of TPU – including the valve. This simplifies the recycling process even further. Reusing Aerothan as bicycle tubes is not possible yet; instead, the recycled tubes enter a second life cycle as sealing or insulation material.
