Freewheel hub and bicycle wheel fitted with the same

摘要

The hub (2) has a freewheel body (40) mounted around an end fitting (23) of a hub body (20). Hollow rollers (100) are arranged in an internal radial groove (41) of the freewheel body, where the rollers are made of polyacetal, poly-ether-ether-ketone (PEEK) or polyurethane. The rollers are elastically deformable between one configuration where the rollers roll on a bottom (411) of the groove and another configuration where the rollers support a radial internal surface (421) of a support (42) and a radial external surface (231) of the end fitting against each other.
