[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. [Remoable Valve Cores] The removable valve cores in bicycle inner tubes make it easier for riders to inspect and prevent air leaks, enhancing the convenience of inner tube maintenance. Variety of Sizes: These TPU inner tubes are available in almost all common sizes on the market. We offer a more professional and comprehensive experience than other TPU inner tubes that only offer a limited range of sizes. For example, 520 size is compatible with 24 inch wheel road bike.

During installation, inflate to 0.35 bar(5 PSI) first, ensuring the inner tube is close to the tire's inner wall. Adjust the inner tube by pressing. Avoid heavy inflation without a casing to prevent irreversible damage; exceeding 0.35 bar(5 PSI) will cause irreparable expansion. Packing List: Each package contains one inner tube and two patches.

【NOTE】

1.Before purchasing, please verify the size of your bicycle tires.

2.Prior to replacing the inner tube, check for any rocks or sharp objects inside the tire to avoid puncturing the inner tube.

3.When installing the new inner tube, remember to add a small amount of air (enough to shape the inner tube, but not exceeding 6 psi), and inspect the bicycle inner tube for any damage. This will prevent the inner tube from twisting, causing pinch flats, or potentially blowing the tire off the rim (when fully inflating immediately), ultimately resulting in inner tube failure.

4.Do not overinflate.

5.Ensure you check tire pressure before every ride.
