I stepped on the nail with the rear wheel and replaced the Tube.
I did not puncture the front wheels, but it is a purchase to make it free shipping as it will become necessary later.
Quality is of course domestic production Manufacturer IRC so it is safe.
Moreover, I am satisfied that it can purchase at a low price.
This time I made it to NORMALTube, but as I go to a more hard place in the future
HardTube - I would like to install a bead stopper too.
