Off-road, tire performance improves with lower air pressure. The tires can adapt better to the ground and react much more sensitively. They roll over bumps more easily and offer more grip and control. At less than 1.5 bar, however, the risk of punctures or the tire rolling too much increases.

The solution is a double chamber system. There is another air chamber inside the tire, which is filled with high air pressure and prevents the tire from puncturing the edge of the rim. At the same time, the inner system secures the tire on the rim and prevents "burping", a loss of air from the tubeless system at low pressure. The air pressure in the outer chamber can now be safely reduced to 1 bar, depending on use.In order to take advantage of the low tire pressure without risking a puncture, Schwalbe and the rim specialist Syntace worked independently on the same idea and also applied for patents for it. The two companies are now joining forces to make the system ready for the market.At the latest at Eurobike, Schwalbe will present precise information on the design and prices. Schwalbe will take over the production and distribution of this system, which is expected to be compatible with conventional tires and rims and weigh less than 200 grams.

One valve for each air chamber - the prototype of this new tire system.
