Strong Compatibility: One size fits most rims, making the selection and transportation of bicycle tubes much easier. Low Rolling Resistance: The TPU inner tube is lighter and softer, creating less friction on the outer tire and rim, resulting in lower rolling resistance and easier pedaling. High airtightness: There is only one circle of connections around the valve, reducing the possibility of air leakage and ensuring that you do not need to inflate frequently during long rides. Puncture protection: The high elasticity and toughness of the TPU material provides the inner tube with additional puncture protection and makes riding safer. Note : 1. After receiving the bicycle tube, do not rush to install it. Please do a thorough inspection to ensure the quality of use. 2. Inflate the inner tube, put it in the water and rotate it slowly to check whether the inner tube is leaking. 3. Do not inflate the tire heavily without installing the outer tire, otherwise it will cause irreversible damage. 4. Please inflate the tire a little before installation to check the tightness. When fitting the tire, first pump some air to make sure the tube adheres to the rim. The tube must then be adjusted by pressing on the tube. 5. Vacuum pump 2-3 times no more than 0.5bar, if more than 0.5bar will cause the expansion cannot be repaired.
