A hub (10 for a wheel incorporating resilient spokes (36) to connect the hub (10) to a rim (38). The hub (10) comprises a hub body (12) having a through hole (14) defining an axis of rotation (A) of the hub (10) and a plurality of spoke mounts (16) for connection, in use, to resilient spokes (36) extending between the hub (10) and a rim (38). The spoke mounts (16) are pivotably mounted in pairs about an outer circumferential surface (18) of the hub body (12) at locations equidistantly spaced from, and about the axis of rotation (A) of the hub (10). Each pair of spoke mounts (16) is mounted for pivotable movement about a common pivot axis (B) extending generally parallel to the axis of rotation (A) of the hub (10). The spoke mounts (16) in each pair are mounted about the outer circumferential surface (18 ) of the hub body (12) so as to be located on opposite sides of a circumferential hub line (C) from each other. The circumferential hub line (C) extends about the outer circumferential surface (18) of the hub body (12), around the axis of rotation of the hub (A) The hub (10) further includes a plurality of damping elements (20), each damping element (20) being coupled between a respective spoke mount (16) and the hub body (12) to control pivotable movement of the spoke mount (16), about the respective pivot axis (A), relative to the hub body (12).
