[Difference: Metal vs. Plastic Valve] TPU inner tubes commonly use lightweight plastic valve, but they often lack airtightness, causing occasional leaks. We tackles this with metal (Aluminum Alloy) valve, maintaining the total weight under 36 grams for a reliable ultra-light experience. Metal valves are also more corrosion-resistant, ensuring added stability during rides.
