A wheel hub for attachment to a wheel rim which includes a hollow axle and a pair of annular bearing assemblies is disclosed. The bearing assemblies have inner and outer annular parts, inner and outer circumferential surfaces, and inner and outer side surfaces. The inner side surface of the inner annular part of each annular bearing assembly engages the ends of the axle in end-to-side abutment. The wheel hub also includes a pair of stops having a wedge end and an axle end. The axle end of each stop may be disposed through one of the bearing assemblies and into one of the ends of the hollow axle capturing a respective annular bearing assembly between the wedge end of the stop and the end of the axle. An annular abutment bracket is press fit over each bearing assembly. Each annular abutment bracket facilitates attachment of the wheel hub to a wheel rim. Each annular abutment bracket also has a lip which engages the outer side surface of the outer annular part of the bearing assembly to which it is attached and prevents the annular abutment bracket from slipping off the bearing assembly under the inward force exerted when the wheel hub is attached to a wheel rim.
