The lightweight and space-saving TPU tube is suitable for both road and off-road applications. High-quality, micrometer-thick TPU is processed in seven layers, achieving optimal air tightness and durability. To ensure the highest material quality and avoid unwanted pressure loss, the tube is not colored. The base of the valve shaft is slightly conical in shape to improve the fit on the rim and reduce unwanted movement during riding. Additionally, the valve shaft features an internal thread that allows for the use of valve extensions or a replacement valve core.
