Abstract: A bicycle wheel and hub can be configured to provide enhanced stiffness, reduced aerodynamic drag, and reduced weight. For enhanced lateral stiffness, the bicycle wheel comprises a hub having a central body bounded by a first hub flange and a second hub flange. Each of the hub flanges includes a plurality of extensions protruding radially outward from the central body towards a wheel rim. The extensions extend at least one-fifth of the distance from the central body to the rim. A pair of spokes spans between each hub flange extension to the rim. The hub of drive side of a driven wheel may further include a reinforcing member such as a reinforcing ring to accommodate forces and loads imparted by a bicycle drive mechanism. For reduced drag while retaining sufficient lateral stiffness, the central body of the hub may be narrowed and the hub flanges correspondingly repositioned laterally inward.

Abstract: A bicycle wheel release mechanism can be configured to fit between dropouts on a bicycle. The release mechanism can have a ramp member and a ramp interface that rotate relative to one another to define a secured position where the wheel is secured to a bicycle and an open position where the wheel is releasable from the bicycle. The ramp member can be keyed to the bicycle such that the release mechanism can be operated or adjusted via single-handed operation. The ramp member can be configured with a variable angle ramp to facilitate rapid application for initial rotation of the mechanism followed by slower application as clamping forces increase when the release mechanism approaches the secured position.
