Foam insert" for tubeless tires and rims. Tire inflation approx. 80 %. You can ride with normal air pressure in the tire. If you lose air, you can continue riding on the foam insert without any problems and the tire will not come off the rim. You can easily repair the tire later.
air pressure corresponds to approx. 0.7 bar. You can ride off-road with a lower air pressure, the airmousse stabilizes the tire and prevents punctures on the rims.
