TPU Inner Tube, Ultra-Light Inner Tube, 45mm Schrader Valve, 45/65mm Presta Valve, for Adult Bicycles or Mountain Bikes

【Wide Compatibility】This inner tube fits most road bikes and is compatible with many tire sizes: 700C x 18C-32C. It also features a 45mm or 65mm Presta valve. Please check the markings on your tire sidewall before purchasing and choose the appropriate size.
【Ultra-Light and Portable】Our road bike inner tube is made of TPU, a material much lighter than traditional butyl rubber inner tubes. When folded, its volume is only 1/3 to 1/5 that of a standard inner tube, saving half the storage space. Lightweight and portable, it's the ideal spare inner tube for your bike.
【Premium Material】The inner tube is made of TPU, a material that offers better puncture resistance than butyl and latex inner tubes. It is also flexible, abrasion-resistant, age-resistant, oil-resistant, and water-resistant. Its low rolling resistance also makes pedaling easier.
【Practical Design】Our inner tubes feature a one-piece, leak-proof valve, ensuring excellent sealing, long-lasting air retention, and reducing the risk of leaks. The wall thickness is 0.2 mm ± 0.03 mm, offering a perfect balance of lightness, strength, and wear resistance. Our inner tubes withstand temperatures ranging from -40°C to 70°C, ensuring stable use even in extreme temperatures.
【Easy Installation】Our inner tubes are easy to install, even for beginners. Before installation, inflate them slightly to a low pressure to prevent them from kinking or twisting. Ensure the rim and the inside of the tire remain clean to minimize the risk of punctures.
