Mr. Wolf’s Mousse Balls are the link between versatility of an inner tube and the anti-puncture and performance features of a traditional mousse. Thanks to the innovative and patented segmented structure, it is possible to completely customize the firmness according to terrain conditions and rider preference. They are ready-to-ride from the very first minute with optimal performance without drilling. Mousse Balls are suitable for any brand or size of tire and offer easy mounting compared to a traditional mousse. Another benefit of the higher surface/volume ratio is the operating temperatures drop up to 33% which greatly improves durability.

Sizing:  90/90-21″, 80/100-21″

Depending on the internal volume and carcass stiffness of the tire and what "PSI" feel desired will determine spacing of the balls. If you lube and load the balls with no spacing, it would tend to equal 16+ psi (more or less depending on how stiff or large the tire is), 1/2" gap 13-14 psi, 1" gap 10-12 psi, 1-1/2" gap 8-9 psi. How much life you get out of a set is greatly increased with the ability to be regenerated by adding additional balls, available separately (see 3-piece option).
** Contains 26 balls.

*** Oversized 90/100 "Fatty" front tires may require additional balls. Sold separately (see 3-piece option).
