A revolutionary dual chamber system makes it possible to ride with very low air pressures and, as a result, improve tire performance enormously. Initially, Schwalbe and the wheel manufacturer Syntace were working on such a system independently of each other. Now, the two companies have joined forces to further develop the dual chamber system...
The solution is an innovative dual chamber system. There is an additional air chamber inside the tire. This inner chamber is filled with high air pressure and effectively prevents the tire hitting the edge of the rim. At the same time, the inner system also secures the tire on the rim and prevents the dreaded "burping", a loss of air of the tubeless system in the case of low pressure. Depending on the situation, the air pressure in the outer chamber can now be reduced to 1 bar (14psi) without running any risk.
