Every M2R hardness matches a fixed tyre pressure. Quick rule: the more technical and slow the terrain, the softer the mousse; the faster and heavier, the harder.
| Mousse | Equiv. pressure | Discipline | Ideal terrain | |
|---|---|---|---|---|
| Bubble Gum | 0.3–0.4 bar | Extreme enduro | The softest in the range. Extreme grip on rock and roots, built for racing. | View |
| Spongy | 0.5–0.6 bar | Hard enduro | Great traction. The durable, affordable choice for enthusiasts. | View |
| Steady | 0.8–0.9 bar | Enduro / racing | King of the track. Hard, durable and reliable, ride after ride. | View |
| Rock Like | 1.2 bar | Trail / raid | Stays on your rim like a rock. The hardest in the range. | View |
Frequently asked questions
Which mousse hardness do I need for enduro?
For traditional enduro and racing, Steady (0.8–0.9 bar) is the benchmark: hard, long-lasting and stable on track. If you ride hard enduro with trials sections, drop to Spongy (0.5–0.6 bar) for extra traction.
Which mousse should I pick for extreme enduro?
Bubble Gum (0.3–0.4 bar) is the softest in the range: maximum grip on rock and roots. Because it is built for extreme use, it needs 2 rim locks fitted so the tyre cannot unseat.
And for trail or rally raid?
Rock Like (1.2 bar) is the hardest: made for heavy trail bikes and long adventures where stability and durability matter more than extreme traction.
How long does an M2R mousse last?
It depends on use, weather, maintenance and the state of the tyre. Store it somewhere cool and dry (below 30 °C) and re-grease it after periods without use.
Can I use the mousse on the road?
No. M2R mousses are strictly off-road; using them on public roads is not allowed.
