Mistake 1: You skip the gel (or skimp on it)

The silicone gel is not a bonus. It is a necessity.

Without gel, friction occurs between the mousse and the inside of the tire. This leads to:

• Shortened lifespan

• Overheating

• Uneven performance

Solution: Always use the included brush and apply plenty of silicone around the entire mousse before assembly.

Mistake 2: You're using the wrong tire size

The mousse must match both the tire's inch size and dimension.
Example:

• Are you running 110/90-19? → Choose SpeedGrip MX (110/90-19) 0.8 bar

• Do you have 80/100-21 or 90/90-21? → Choose SpeedGrip MX / ENDURO (90/90-21) (80/100-21)

Wrong size = unnecessary hassle during assembly and poorer driving feel.

Mistake 3: You stress during assembly (and damage the mousse)

Forcing the mousse in with too much force, the wrong tool, or without patience is a recipe for:

• Depressed parts

• Uneven fit

• Damage to the foam

Solution: Take it easy. Warm up the tire beforehand – it makes it a lot easier.

Mistake 4: You reuse old mousse “just one more time”

It may sound tempting. But mousse is a consumable item – and once it loses its elasticity or becomes dry and cracked, it's time to replace it.

An old mousse can:

• Feeling “dead”

• Release the grip

• Roll unevenly

And that increases the risk of injury to both the bike and the rider.

Mistake 5: You forget to check the condition of your tires

Mousse + worn out tire = bad combo.
It doesn't matter how good the mousse is if the tire is dry, cracked or unevenly worn.

- Always check the tire before mounting.
- Replace both at the same time if necessary.
