The Gibson Mousse Assembly Gel is mandatory when using the Mousse products.
Primarily, this silicone-based gel is designed to affect the temperature of the mousse created by the rotation and friction of the mousse against the inside of the tire while riding - in other words, to cool the mousse.
Secondarily, this gel also serves as mounting support. The mousse must in no case be used only with talcum powder, as known from conventional tube mounting. The use of the gel is essential because the gel has a significant influence on the durability of the mousse and prevents damage to the mousse.
