Abstract
A free wheel assembly with front clutches comprising a hub sleeve rotatable on a hub pin and a cassette rotatable on the hub pin, a first annular body rotatable on the hub pin and comprising a first crown gear, a second annular body associated with the hub sleeve and comprising a matching second crown gear facing the first crown gear. The first annular body is axially movable relative to the second annular body between a motion transmission configuration and a free wheel configuration and coupling members operate between the first annular body and the cassette. In the free wheel configuration, rotation of the cassette relative to the first annular body forces the coupling members to axially translate the first annular body towards the second annular body, and magnetic members active on the first annular body and opposing the rotation of the first annular body with respect to the hub pin.
