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