I had seen it on TV over this tube. Even the fishermen stole the patent and do not mind coming to a small business, since the giant Hermes puts logistics behind. I must say that I have 2 left hands as regards the craft. Never again will I buy another bicycle tube !!!! In 7 to 10 minutes is changed. Fahrraddecke solved one side. The old hose cut out and the new clean. Strictly again. I mean the Fahrraddecke and air inflate. Finish !!!!!!!!!!!!! Only important an air pump should have the Presta valves also inflates. Are there commercially. For the way a dream when one suddenly has a flat tire. No removing the wheel longer necessary and this very quickly. For me there is only this bicycle tubes !!!!!!!!!!!!!!!!!
