ABSTRACT:
A bicycle wheel mounting assembly includes an inner sleeve that is hand-threaded onto external threads of a solid bicycle wheel axle. An operating handle includes two cams eccentrically mounted thereon and is rotatably mounted on the inner sleeve to rotate those cams about an axis that extends transverse to the inner sleeve longitudinal axis. An outer sleeve is mounted on the inner sleeve to be moved longitudinally of the inner sleeve by the cams. The inner sleeve is hand tightened onto the axle until the outer sleeve abuts the bicycle wheel, whereupon rotation of the operating handle causes the cams to force the outer sleeve forward so as to force the bicycle wheel snugly against the bicycle frame. A boot is also included, and the entire assembly thus includes quick-release features.
