Once the valve core leaks, it will seriously affect the speed of the bicycle, so it must be dealt with immediately, but sometimes the valve core leaks are not so obvious. It shows a slow leak. The situation cyclists must pay attention to. Slow air leakage of the valve core generally occurs in winter. Because the valve core is mostly made of rubber, it will become very hard in cold weather and its elasticity will be greatly reduced. At this time, the sealing effect is the worst, so slow air leakage will occur. The phenomenon, then, what is a good solution at this time?
In view of the slow air leakage of the tire valves, a layer of valve sleeve can be placed on the outside of the valve core, which can play a certain role in heat preservation and prevent the influence of bad weather on the valve core. Or you can take the time of pumping up to pull out the valve core, and then apply a layer of glue around, but be careful not to block the pores, and then immediately plug it back onto the valve mouth.
The above two methods can solve the slow air leakage phenomenon of the valve core, which mostly occurs in winter, and car owners only need to pay more attention to protection when the weather is cold. Air valve core leakage is a matter of concern, because air leakage in the tires will reduce the speed of the bicycle.
