  "textContent": "The invention discloses a freewheel system (1) for a bicycle hub (10), comprising an inner ratchet (31) fixed to a hub body (11) and an outer ratchet (21) fixed to a freehub (22). This system (1) is particular in that an internal surface of the inner ratchet (31) is coupled to an external surface of a connection shell (34) joined to the body (11), where a diameter of the internal surface of the connection shell (34) is larger than a diameter of a bearing (RC2) connecting the hub body (11) and the axle (E). Similarly, also the coupling between the outer ratchet (21) and the freehub (22) can be carried out by the interaction between the internal surface of the outer ratchet (21) and the external surface of the freehub (22). The invention is also directed to an inner ratchet (31) and to an outer ratchet (21).",
