Tube of the strongest class (Front)
I used to favor IRC's Heavy tube usually "SUPERHeavy tube for competition" I am also interested in what exactly what is called, I purchased it.
I took it out of the box, removed the musk from Valve, and threw it out with a point, I sucked in air and inflated like Donut naturally. It does not become like a NORMALTube, it becomes a state of a picture w
As the name of Super heavy, it's thick and very strong.
That's probably, people who are not familiar with exchanging Tire think that Tube is too thick to have trouble.
And of course it is heavy.
What you get is more secure than the Heavy tube "It is hard to puncture".
However, weight and replacement are also included without omissions.
【Condition that is terribly prone to puncture, inevitably you have to run on Tube】
【In case of Situation that Ikan is absolutely Puncture】
I think that I will use Super heavy again when it comes to the situation, otherwise I felt that normal Heavy tube was enough.
