The mousse bounces more slowly than an air-filled tube. This is due to the inertia of the material. Some riders report a rather unstable ride feeling in the beginning. This sensation usually only occurs during the acclimatization phase after switching directly from tubing to mousse. If one is the first day on Mousse on the road, however, this feeling turns off with time.
What a mousse does not tolerate at all, are maximum speeds, the rear wheel can swing strongly, the temperature of the mousse rises extremely and can act up to the destruction of the mousse.
So - do without high speeds in any case!
