(google translate)From Italy there's news regarding an innovative system that could compete on the card to the now proven Tubeless, especially in disciplines where Gravity is still used very air chamber for risks bead. This system uses an internal palmer (without a tubular tire that seems to be produced by a large company) and a classic tire outside.
The tube is used without being inside the tire tread because there is neither the need, and so also reduce the cost and weight. The palmer has the function to reduce to almost 0 pinch flats because acts as a protection to the rim. In case of puncture of the tire outside the palmer we will arrive at the finish without any problems.
The system say it also works on the road bike and is recommended for races such as the Paris-Roubaix where we saw how many times the runners lose the right group because of a puncture. In case of problems or else you can go back to using the normal circle mode 'only tubeless' or inner tube.
