The air injection valve was looking for a rice type type used for automobiles etc.
However, in the desired size 22 × 1-3 / 8, only English type used for bicycle etc. can be found.
Although rice type requires a little accustoming to the operation at the time of air injection,
It is much more durable than British style and has less air leakage,
I absolutely wanted a rice expression.
So we bought 22 × 1 thin one sizey of this one.
At this time the wall of the tube is stretched in the tire,
There was concern that the space between rubber molecules spread and air leakage became faster,
Because the quality of rubber is good for the highest level, the decrease in air pressure is kept to a minimum.
However, complete satisfaction can not be obtained if there is no object of the proper size.
A hole in a pinhole was opened. Since it can not be helped, trying repair is also thinning the thickness of the pollen flooring tears when rubbing the surface with a file because of adhesion · · · It is thin. I think that it is better to stop handling.
