For example, after a long time, some places will leak air quietly, accidentally hit nails and other problems, which are easy to repair. It is worth noting that our self-repairing inner tube can be used within the normal temperature environment and cold days -15 ℃ , and it is more conducive to travel in cold weather. 🚴‍♂️【Please note】 1. Because the Self Sealing fluid is flowing, in order to prevent the liquid from flowing out during operation, please do not concentrate the center of gravity or the liquid near the air nozzle when pumping up. 🚴‍♂️【Safe Bike Tires】 Pre-installed with Sealant to provide maximum puncture protection and prevent flat tires on your bike.The self-repairing inner tube is a thicker design, which is more durable than the normal inner tower. The bicycle inner tube rolls through the tire repair liquid to automatically fill the punctured area. After testing, the leak can be repaired within 5~8 seconds under normal conditions.
