UltraLight TPU Inner Tube for Road, MTB, Gravel, and EBikes Experience a lighter, stronger, and more reliable ride with our advanced thermoplastic polyurethane elastomer (TPU) inner tube, engineered for performance across multiple cycling disciplines. Key Features and Benefits UltraLight Construction: Made from quality TPU material, this inner tube is approximately 70% lighter than traditional butyl rubber tubes, reducing overall bike weight for improved handling and easier portability. Ideal for riders who value speed, efficiency, and convenient storage. Puncture Resistance and Durability: TPU offers outstanding puncture resistance, wear resistance, and longlasting performance. It minimizes the risk of sudden flats and maintains stable function even at lower tire pressures, making it dependable in challenging terrains. The material is also resistant to oil, water, and aging, ensuring consistent loadbearing capacity over time. Enhanced Air Retention: Equipped with precisionengineered presta valves (45mm or 65mm length options) to match various rim profiles. Optimized internal structure reduces air leakage, while valve pad rubber helps minimize friction between the tube and tire for smoother rides and prolonged tube life. Wide Compatibility: Designed to fit a range of tire sizes for different bikes, including MTB, ebikes, and gravel bikes. Suitable sizes: 24', 26', 27.5', and 29' wheels Compatible tire widths: 1.3–2.0 and 1.9–2.5 Includes a bike tube patch kit for quick, onthego fixes. Practical Applications Road Cycling: Reduce bike weight for faster acceleration and maintain air pressure stability during longdistance rides. Mountain Biking: Enjoy strong puncture resistance for rugged trails while keeping handling light and responsive. Commuting and EBiking: Dependable air retention and robust load support for daily travel, wet conditions, and varying road surfaces. This TPU inner tube delivers the combination of light weight, strength, and versatility that modern cyclists need for both performance and reliability.
