The use of road big tires and low pressure inflation are the guide lines for this device, which can combine the highest level of safety and the lowest possible increase in weight.

The best in terms of run flat performance.

It lacks the lower air channel because inflations are too high to make it work properly.

Specifically designed for 28c to 32c tires paired with modern wide rims.

Tested in the worst conditions, already winner at the Giro dItalia in the Montalcino stage.
