Aerothan is a material that completely redefines bicycle tubes: extremely light, with maximum puncture protection and designed for minimum rolling resistance. AEROTHAN TUBE. IS THIS STILL A BICYCLE TUBE? 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. THE FACTS. - 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 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. THE WONDER MATERIAL FROM THE SCHWALBE INNOVATION HUB. 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. SETS NEW STANDARDS WHICH IS FURTHER DEMONSTRATED DURING TESTING Prior to market release of a Schwalbe innovation, we carry out numerous tests to assess its quality. The Aerothan test results speak for themselves. AEROTHAN TUBE RACE For road riding with tubes, the Aerothan tube is the first choice. It offers low rolling resistance with dynamic, smooth riding characteristics.Compared to butyl tubes, a total weight reduction of 100g may be achieved for the entire bike. Aerothan Tube Race offers not only reliable puncture protection, but also safety when descending a mountain: Even when several emergency brakes are applied with rim brakes in short sequence, one can count on its heat resistance capacities. AEROTHAN ENDURANCE RACE Purpose : Road/CX/Gravel Designation : SV16E Wheel size : 28" / 700C ETRTO : 28-622 to 35-622 Valve : SV, 80MM Weight : 54g - Made in Germany, 100% recyclable, Approved for rim brakes.
