Abstract
A bicycle axle assembly is provided with an axle including a rotational axis, a bearing, a bearing adapter and a conical element. The bearing includes a cone disposed on the axle, a cup and a plurality of roller elements disposed between the cone and the cup such that the cup rotates relative to the cone about the rotational axis. The bearing adapter includes a tubular mounting section for mounting to a tubular member and a bearing housing section housing the bearing therein. The bearing housing section has a tapered abutment angled relative to the rotational axis at a first abutment angle and contacting a tapered contact surface of the cup. The conical element is disposed on the axle. The conical element has a tapered abutment angled relative to the rotational axis at a second abutment angle and contacting a tapered contact surface of the first cone. The second abutment angle of the tapered abutment of the conical element is smaller than the first abutment angle of the bearing housing section.
