Michelin Bib Mousse Enduro Rear Inner Tube 140/80-18 55071

When you're pushing limits on the track or trail, your tire system needs to match your commitment to performance. The Michelin Bib Mousse Enduro is purpose-built for off-road competition, delivering consistent pressure and enhanced traction where traditional inner tubes fall short. This is the tube choice of serious competitors who refuse compromises on terrain control and durability.

The Bib Mousse system uses multi-cellular butyl construction to maintain a stable pressure equivalent of approximately 13 psi, giving you predictable handling across rocky, sandy, and mixed terrain. Its engineered compliance reduces pinch flats and allows for lower effective pressures without the risk of rim damage—critical advantages when you're racing hard. Installation is straightforward with the included Bib Mousse Fitting Gel, which ensures proper seating and eliminates air pockets that could compromise performance.

Designed exclusively for Michelin off-road tires, this tube is engineered to work in harmony with proven tire compounds and carcass construction. Not rated for on-road use, so keep this system where it belongs: in competition.
