ABSTRACT:
A bicycle wheel hub has identical endwalls which mount outwardly directed bosses for engaging in mating recesses of a self-contained freewheel mechanism to enable the freewheel mechanism to be mounted to the hub with a positive engagement to the hub rather than being threaded onto a hub extension. The assembly also incorporates sealed bearings which insert into seats recessed into the opposite ends of the axle bore, with the radially inner races of the bearings being captured axially on both sides, on the inside by an enlarged central axle length, and on the outside by sleeves which are slipped over the reduced axle end extensions and bear against the bicycle mounting forks to define a straight compressive chain through the sleeves, inner bearing races and central axle portion so that compressive stresses are not exerted on the bearings by the mounting of the hub to the fork.
