<p>A hub assembly has a hub body (51) for carrying a rim support, a mounting structure (54) fixedly mountable to a bicycle fork and a bearing structure (57) between the hub body (51) and the mounting structure (54). A drive sleeve (52) is suspended for rotation about the main axis and coupled to the hub body (51) for driving rotation of the hub body about the main axis. A drive wheel carrier (53) is coupled to the drive sleeve for driving rotation of the drive sleeve (52). A bearing member (56) between the drive wheel carrier (53) and the drive sleeve (52) axially guides the drive wheel carrier (53) along the drive sleeve (52). At least one projection (53; 520-523; 531-533; 534-536) projects between the drive wheel carrier (53) and the drive sleeve (52). The bearing member (56) includes a bearing part circulatable about the projection (53; 520-523;531-533;534-536).</p> |
