MICHELIN Mousse — Off-Road, Butyl foam

Bib Mousse™ is a proven foam-based insert placed between rim and tyre instead of a conventional inner tube. It cannot go flat and offers a pressure equivalent of 0.9 bar, while being lighter than a reinforced inner tube. 🛡️🚵‍♂️

Proven competition record: 36 Dakar victories since 1983, 22 Enduro World Championship titles and 7 MX World Championship titles.

How it works: the foam composition sits between rim and tyre, eliminating the rapid loss of pressure that a puncture causes. The system provides consistent contact pressure and predictable handling across rough terrain.

• Eliminates the risk of punctures during trail and competition use.
• More durability: designed to fit precisely into compatible tyres for outstanding robustness.
• Optimised grip and handling: developed to enhance tyre performance in grip and control.

Important: designed for trail and competition use only; not approved for road use.
