Versatile Size Range: The ultra-light road bike inner tube fits a range of tire sizes, including 700x32-47C, ensuring compatibility with various gravle bike tire sizes. Ultra-Lightweight & Durable: Made with advanced TPU technology, weighing only 45g—striking a perfect balance between lightness and durability. Enhanced Air Tightness: These inner tubes feature metal valves instead of plastic ones, ensuring superior air tightness and reliability. The metal valves are also more corrosion-resistant. Multiple Valve Length Options: With a choice of 45mm, 65mm, or 85mm Presta valves, you can select the valve length that best suits your needs. Proper Inflation Tips: Do not overinflate when not installed in the tire (to avoid irreversible damage).
