How springs work

The primary and secondary springs are mounted in such a way as to guarantee a preload which generates an initial resilient spring force.

How the primary spring works

When the lever is actuated, the preloading position of the primary spring is varied and reduced. The spring returns an elastic force of contrast to the action of the lever.

How the secondary spring works

The torque generated by the rear wheel tends to raise the drum. The secondary spring is compressed with respect to the initial resting position and generates an elastic contrast force.
