Features1TPU Material: Made from TPU (thermoplastic polyurethane) material, it offers exceptional abrasion resistant and puncture resistant. Even in complex road conditions, it effectively reduces the risk of punctures and prolongs service life. 2Suitable for Various Road Conditions: TPU inner tube allows it to better conform to the inner shape of the tire, providing more uniform pressure distribution. This ensures good contacting between the tire and the ground during rides, enhancing comfort and handling. 3Strong Air Tightness: It features sealing performance, making it less prone to leaks. Whether for daily cycling or long distance trips, it maintains stable tire pressure, eliminating the need for frequent inflation, providing convenience and peace of mind. 4Ultra Lightweight Design: Compared with traditional rubber inner tubes, the TPU inner tube significantly reduces weight, achieving a 244% decrease in weight compared to ordinary inner tubes, enhancing cycling efficiency and making it easier to carry. 5All Season Use, Heat and Cold Resistant: TPU material has good temperature adaptability, maintaining stable performance in both hot summer and cold winter conditions. This ensures a seamless and safe riding experience year round.SpecificationItem Type: TPU Inner TubeMaterial: TPUPackage List1 x TPU Inner Tube
