Performance & Ride Feel
A conventional inner tube can lose pressure after a puncture or pinch flat, immediately affecting handling and potentially ending the ride. A mousse uses a solid cellular construction inside the tyre, so there is no air pressure to lose and no inner tube to puncture.
The approximate 10-12 psi feel provides dependable tyre support while allowing the rear tyre to conform to uneven terrain. This can improve traction and control across rocks, roots, ruts, loose climbs and changing trail conditions.
Because the mousse maintains a consistent feel throughout the ride, riders can focus on the terrain without regularly checking or adjusting rear tyre pressure. Correct installation, lubrication and tyre compatibility remain essential for achieving the intended performance.
Compatibility & Fitment
This mousse is intended for compatible 18-inch rear off-road tyres requiring a 340 mm mousse. Tyres with the same wheel diameter can have different internal dimensions, carcass profiles and construction, so compatibility should not be determined by rim diameter alone.
Confirm the required mousse size for your chosen tyre before installation. Correct compatibility helps provide the intended 12–13 psi feel, supports easier installation and reduces the risk of excessive heat or premature mousse wear.

German-Made Quality
Manufactured in Germany using high-quality materials, Mefo Mousses are trusted for their consistent performance, dependable fitment and long service life. Their cellular construction is designed to withstand the repeated impacts, heat and deformation encountered during demanding off-road riding.
Installation & Care
Mousse gel is included for the initial installation. Apply the entire sachet evenly during fitting to reduce friction and heat between the mousse and tyre.
Periodically remove, inspect and re-lubricate the mousse to maintain flexibility and maximise its service life. Riding speed, temperature, terrain, tyre construction, lubrication and storage conditions can all affect mousse wear.
Use appropriate mousse-fitting equipment and take care not to damage the tyre bead or mousse during installation. Professional installation is recommended if you are unfamiliar with fitting mousse tubes.
Use Rim Locks
Rim locks are strongly recommended to help prevent the rear tyre from moving on the rim during hard acceleration, braking and technical riding. Correctly installed rim locks support consistent performance and help keep the tyre securely positioned.
Off-Road Use Only
This mousse is designed specifically for off-road riding and competition. It is not intended for extended highway or high-speed road use, where sustained heat can shorten mousse service life.
