Abstract: An aerobar assembly for a bicycle that generally includes an aerobar, an adaptor and a control cable guide. The aerobar includes proximal and distal portions and proximal and distal ends. The aerobar has a generally hollow interior. The adaptor mounts an actuator assembly to the aerobar. The adaptor includes an interiorly-disposed portion and an exteriorly-disposed portion. The interiorly-disposed portion is disposed in the hollow interior of the aerobar and is bonded to the distal portion of the aerobar. The exteriorly-disposed portion is configured to receive the actuator assembly. The control cable guide is configured to slidably receive a control cable therethrough. The control cable guide is coupled to the adaptor such that the control cable enters the distal end, extends through the interior of the aerobar, and exits the proximal end of the aerobar.

Abstract: A handlebar for a bicycle has first and second laterally extending portions disposed outboard of a central attachment portion. Each of the first and second laterally extending portions is preferably winged-like in configuration to provide reduced air resistance. The first laterally extending portion includes an aerobar clamping mechanism, and the second laterally extending portion includes a second aerobar clamping mechanism. Each aerobar clamping mechanism includes a tapered receiving sleeve having an axis that is generally parallel to a travel axis of the handlebar. A collect having a major axis that extends in a plane generally parallel to the direction of travel of the bicycle is receivable within the receiving sleeve. The collet includes a plurality of axially extending slots that permits the diameter of the collet to be varied. The collet includes an aerobar receiving slot having a major axis that is generally co-linear with the axis of the collect, and is provided for receiving an aerobar.

Abstract: A hub for a human powered vehicle includes a rotation axis, a hub body formed generally symmetrically about the rotation axis, the hub body having a radially-outward-facing surface that includes a plurality of surface features for improving the aerodynamic efficiency of the hub as it passes through a fluid, and a wheel assembly attachment member formed along a circumference of the hub body, the wheel assembly attachment member being structured for attachment to one of a plurality of spokes and the center of a disc wheel. The surface features may include a series of depressions or a series of projections, and such features may have a dimple shape that can be formed in a variety of shapes including those with a cylindrical wall and a planar bottom or a hemispherical bottom. Alternately, such surface features may have a hemispherical shape.

Abstract: A carbon fiber bicycle crank includes an axle lug, having a portion for receiving a crank axle. A foam core is coupled to the axle lug during a first molding process. A pedal engaging lug is coupled to the foam core after the completion of the first molding process, and a carbon fiber composite material exoskeleton is coupled to and disposed exteriorly of the axle lug, foam core and pedal lug.

Abstract: A bicycle wheel includes a tire engaging portion located at the outward perimeter of the wheel, an inner portion located radially inward from the tire engaging portion A pair of air engaging side surfaces extend radially between the inner portion and the tire engaging portion forming the sides of the wheel. The air engaging side surfaces contain a plurality of surface features designed to create a turbulent boundary layer when the wheel travels through air to reduce aerodynamic drag on the wheel.

Abstract: A fiber resin plastic (FRP) based bicycle rim includes an FRP body and a metal tire receiving ring. The FRP body has first and second side surfaces, an annular outer edge surface, and an annular inner edge surface. The annular inner edge surface includes at least two spoke receiving ports for receiving and supportively coupling at least two spokes to the FRP body. The metal tire receiving ring is coupled to the FRP body and is disposed radially outwardly of the FRP body. The tire receiving ring includes first and second, generally parallel continuous braking surfaces.
