ROCKBROS Bicycle Inner Tube 700C 23 25 28 35 Butyl Rubber Inner Tube Road Bike Tire Schrader Presta Valve

Precautions for the use of inner tubes

1. Before installation, clean the inner side of the outer tire to avoid the sharp objects of sand and gravel remaining in the outer tire from piercing the inner tube.
2. It is normal for the new inner tube to be inflated unevenly, because the rubber of the inner tube is different in thickness, and the valve will be thicker. When the pressure is the same, the expansion size is also different. The following can be used normally, and it is not a quality problem.
3. Due to improper installation, the inner tube is damaged, and there are non-quality problems such as air leakage after use, which cannot be returned.
4. To ensure the service life, please do not expose it to the sun for a long time.
5. The inner tube is a consumable item. If you encounter problems within 7 days of receiving the goods, please contact us in time.
