We have replaced the rear tire of Naoyan's SR400.
This bike was once his ride, when in high school.
We will continue to use the valve cap.
This tire has too scuffing. It has reached the cloth.
We were working with me and Naoyan, 2 people.
Uncle are close to each other.
I showed off a finger power.
When fitting the tire, it was allowed to puncture the tube. It is a tragedy.
It's no use crying over spilt milk.
After a few tens of seconds of silence,
We remove the tire, it confirmed the tube.
It was impossible to repair. Hole is too large.
We ordered the tube again,
At a later date, re-assembly.
So tragedy was ceased.
