The Aerothan Tube 29" MTB+ from Schwalbe is the high-end alternative to traditional bicycle tubes. The Aerothan is a next-generation tube that sets entirely new standards in weight, puncture safety, riding characteristics, ease of installation, and packing size. It is approximately 40 percent lighter than a comparable Schwalbe Extralight butyl tube. It is made from durable and fully recyclable Aerothan. The material was developed in collaboration with BASF and is a thermoplastic polyurethane (TPU) that meets extreme demands. Another special feature is the processing with a high-precision laser that welds the valve and tube together. This patented process allows for extremely flat seams that not only ensure precise riding behavior but also play an important role in puncture safety. Ultimately, the seams are subject to extreme mechanical stress. As a result, the tube impresses with its remarkably low rolling resistance at tubeless level. It remains extremely stable even at low air pressures. Additionally, the high puncture protection prevents sudden air loss, making it ideal for cross-country and marathon use, even on challenging trails.
