The belts are manufactured in Switzerland according to the original dimensional specifications but achieve greatly improved elasticity, service life and traction through an improved rubber compound.
Rotational stability is assured through the elimination of slippage and maximum economy of rotational force.
Optimal decoupling of the chassis from the plinth requires the correct balance of rigidity and elasticity in the decoupling "mushrooms". Over time, the rubber becomes hard and brittle, reducing its elasticity and damping properties. Brittle, damaged mushrooms must be replaced. We have worked to develop higher quality replacement mushrooms with extended life and improved damping. Replacing old, brittle mushrooms in many cases is sufficient in itself to dramatically reduce rumble.
Metal supports for the decoupling mushrooms (mushroom tops) facilitate propoer adjustment of the chassis. Friction is reduced by eliminating direct contact between the mushrooms and the levelling mechanism on the chassis rim. Horizontal levelling can be achieved with greater ease and precision.
