Description
Competition off-road riding demands tire solutions that eliminate pinch flats and reduce rotating mass without sacrificing durability. The Michelin Bib Mousse® replaces traditional inner tubes with a multi-cellular foam construction that maintains consistent performance across rough terrain while keeping your front wheel lighter and more responsive. If you’re running Michelin StarCross or Desert Race tires in sanctioned events, this is the proven choice for maximizing grip and minimizing mechanical failures.
