If the air of an old bicycle begins to escape, suspect the deterioration of bug rubber before puncture




My bicycle. I have been riding for more than 10 years.

The day after I got on recently, the air was a little out, and I was putting in air each time.

I had no knowledge of bicycle maintenance, but there was a puncture repair kit, so I removed the tires and looked for a hole in the tube.

Then I found that air was escaping from the vicinity of the valve, not a hole.

When I examined it, I found that rubber rubber deteriorated and seems to leak air

When I looked into it, I found a product that doesn’t need rubber and lasts 6 times longer than that of rubber.

Bridgestone Super Valve Set

There is no problem with quality because it is made by Bridgestone!

Easy to replace. If you put in the air, there will be no air loss the next day.

I wasn’t punk

Since there are two, I exchanged both the front and rear wheels

It was happy
