The assembly of a Mousse is in any case different from the assembly of a conventional hose. Whereas with hose assembly you have the option of even driving the prepressure of the hose close to zero, it is only possible to reduce the existing volume of the mousse to a limited extent. Limited in this case means that I can minimally compress the mousse with pressure over my knees once it has been inserted into the tyre and the tyre has already been pulled over one rim flange. The installation instructions included with each Gibson Mousse illustrate how to install it. However, if there are any uncertainties, it is advisable to ask for assistance from a specialist dealer for initial installation.
