Title: Quick release dropout and wheel hub assembly

Abstract: The present invention relates generally to bicycles, and more particularly to front wheel hub assemblies for bicycles and motorcycles. Specifically, the present invention provides a novel wheel hub assembly for connecting a wheel rim to the front fork of a bicycle or motorcycle, with this same wheel hub assembly comprising an oversized single member hub-axle assembly for attachment to a fork dropout having an enlarged opening. The wheel hub assembly according to the present invention comprises an axle (or axles), a bearing assembly, a hub having flanges for connection to the wheel rim (e.g., via spokes), and a quick release clamping mechanism for securing the wheel hub assembly to the front forks of the bicycle. Additionally, the present invention provides a wheel hub assembly having an axle with an increased diameter and a dropout with an increased size at the axle/dropout interface in order to yield a more rigid interface between the wheel and fork, and provides a more stable bicycle.
