Installation lubricant from Mitas, formulated for fitting and running any Mitas Mousse insert. Cuts friction between the foam mousse and the inside of the tyre during installation, making the fit easier and protecting the mousse from damage as it goes in. After installation, the gel keeps coating the tyre's inner surface, slowing the heat-related breakdown that wears any mousse out over time. Using a proper mousse gel is essential, not optional. Fitting a mousse dry tears the foam during installation, and running one without lubrication dramatically shortens its lifespan. One tub typically covers several installations. The natural paired purchase for any tyre in the Mitas Mousse range, and worth reapplying whenever you swap tyres on a mousse-equipped wheel.
