Abstract: A bicycle handlebar assembly that includes a body having at least two grip areas positioned for interaction with the hands of a rider. The grip portions or grip areas are preferably spaced apart by a center portion that secures the assembly to a bicycle steerer tube. A channel or detent is formed in the body proximate at least one, and preferably proximate each grip portion or grip area. A dampener formed of a different material than the body is disposed in the detent and dissipates at least a portion of vibration of the body to reduce vibrations communicated to the hands of the rider from handlebar vibration. An optional grip assembly cooperates with the handlebar assembly and is constructed to further dampen handlebar vibration.

Abstract: A bicycle frame assembly having a number of elongate tubes that are connected to define a shape of the bicycle frame. The assembly includes a passage that is defined by the elongate member, a partition, and a bridge. The partition isolates the passage from an interior volume of the elongate tube. The bridge extends in a direction normal to an elongate direction of the passage and defines an inlet and an outlet of the passage. The inlet, outlet, and bridge are generally flush with an exterior surface of the elongate tube and provide a passage that cooperates with a flexible connector, such as a cable tie, for securing supplemental structures, such as brake and shift control cables, to the elongate tube of the bicycle frame assembly.

Abstract: An apparatus comprising a valve stem. The valve stem assembly can be part of a rim or inner tube. The valve stem assembly can include a valve core body and a valve stem. The valve core body can be sealed to the valve stem by a valve core body seal. The valve core body can include a spring-loaded pintle that can be configured to open and close when a pump head is attached. The valve core body can include a groove configured to retain a locking device of a pump head. The sides of the groove can be eased, for example, chamfered or filleted. The tip of the valve core body can be eased, for example, chamfered or filleted.

Abstract: An apparatus including a seat post. The seat post can include an upper post, a lower post, a first mechanical energy source, a second mechanical energy source, and a control mechanism. The first mechanical energy source can be configured to contract the lower post and the upper post. The second mechanical energy source can be configured to expand the lower post and the upper post. The control mechanism can be configured to activate the first mechanical energy source to contract the lower post and the upper post to a first predetermined position.

Abstract: A bicycle seat apparatus including at least one rail and a saddle shell. The at least one rail can include a first mounting portion. The first mounting portion can include an ankle. A cross section of a terminus of the ankle can be larger than a cross section of the at least one rail. The saddle shell can include at least one mounting cup configured to mate with the first mounting portion of the at least one rail. A cross section of a base of the at least one mounting cup can be larger than a cross section of the terminus of the ankle.

Abstract: An apparatus including a hub shell. The hub shell can include a hub body; a first spoke flange; and a second spoke flange. The first spoke flange and the a second spoke flange can include a fiber reinforced plastic. The fiber reinforced plastic can include fibers having a range of lengths between 0.2 and 3 inches.

Abstract: An apparatus for a bicycle including a stem body and a mount. The stem body can include at least one handlebar clamping surface and at least one mount clamping surface. The mount can include a first clamping surface. The first clamping surface can be configured to match at least one mount clamping surface. The mount can be configured to clamp between the stem body and a handlebar.

Abstract: An apparatus including a bicycle wheel rim. At least a portion of the bicycle wheel rim can include a braking material. The braking material can have a roughness of about 1 micron to about 80 microns.

Abstract: A bicycle air shock absorber assembly that includes a hollow piston rod that is telescopically associated with a hollow compression rod. The piston rod and compression rod are positioned within the casing of the shock assembly. A piston is supported by the piston rod and divides the volume of the compression rod to form a negative air spring chamber and a positive air spring chamber that includes the volume of the piston rod. An optional coil spring is positioned within the casing and contributes in parallel with the positive air spring chamber to resist compression of the shock assembly.

Abstract: A bicycle seat assembly having an adjustable width nose portion includes an H-shaped base that supports a lateral left side pad and a lateral right side pad. A rail extends under the base and between the left and right side nose portions of the seat assembly. A front rail mount includes a housing, a shuttle, an actuator, and left and right mount supports. Operation of the actuator alters the position of the left and right mount supports relative to the housing and thereby alters a distance between the respective left and right side nose portions of the seat base.

Abstract: A bicycle wheel hub assembly having a number of light emitting diodes (LED's) that are powered by rotation of the wheel during use of the bicycle. The hub assembly includes a magnet and a coil that are both internal to the hub. The light emitting diodes are powered by current induced in the coil and controlled so as to preferably prevent illumination of discrete LED's when the respective LED's are directed toward a user during rotation of the hub. The LED's are supported by the hub and rotate with the hub during rotation of the wheel. In some embodiments, the LED's are attached to the hub at locations that are both laterally inboard and laterally outboard relative to a spoke flange of the hub assembly.

Abstract: The bicycle frame of the invention is formed by selecting and adhesively joining previously formed and precured composite tubes to previously formed and precured composite lugs. The precured lugs are shaped from preforms comprising a plurality of resin impregnated fiber reinforced layers formed into a stacks having the fibers of adjacent layers cross one another, with preforms of each lug component being a set of shaped overlapping segments of the lug to be formed. The overlapping segments are then brought together and placed around an inflatable bladder to form an assemblage that is placed in a female mold, preferably of two halves, that are closed for forming the lug. The resulting assemblage is cured, with the bladder pressurized for urging the respective preforms to the mold shaping surfaces, providing a high laminate compaction during cure for a uniform, thin walled, strong, tubular, lug. The lugs are preferably formed with one or more plugs for closely fitting into adjacent open ends of the tubes.
