Abstract: Nubbed grips for hand-rotatable bicycle gear shifters have longitudinally elongated groups of nubs (50, 96, 142) that are angularly spaced apart by valley regions (44, 98, 156). Preferably, the elastomeric nubs are formed both on a cylindrical portion and an adjacent flanged portion of the grip. In an alternative embodiment, shark tooth nubs (142) offer leading faces (158) against which a hand of a rider may abut in either rotational direction for maximum torque transmission.

Abstract: A rear derailleur (50) is provided with an arcuate cable entraining surface (78) which substantially reduces the variation and magnitude of the actuation ratio between control cable linear displacement and movement of the derailleur p-knuckle (88). A b-knuckle flange (160) militates against the derailment of the drive chain from the upper guide wheel while permitting maximum lateral flexing of the drive chain (48) during shifting between sprockets (46) on the freewheel. A rigid arcuate surface (174) may be provided as an extension of the b-knuckle (170) in replacement of a segment of a Bowden cable housing (38) to obviate the accumulation of water and foreign matter.

Abstract: A bicycle gear shifting system having rotatable front and rear handgrip shift actuators operatively associated with control cables for shifting respective front and rear derailleur mechanisms. In some forms of the invention the control cable is directly actuated by the handgrip rotator, while in other forms the shifter rotator drives a separate "jack spool" which in turn actuates the control cable. A cam on either the handgrip rotator or the jack spool is configured so as to substantially compensate for increasing force of the derailleur return spring during down-shifting. Compensation is provided in the shift actuators of the invention for various lost motions in the derailleur shifting mechanisms and control cable systems. The shift actuators of the invention also provide overshift movement of the derailleur mechanisms in the down-shifting direction so as to overshift the bicycle chain a sufficient amount beyond the destination derailleur sprocket so that the chain will approach the destination sprocket in the same direction as it would in the up-shifting direction. The shift actuators of the invention also provide equalization for the higher derailleur return spring force during down-shifting than during up-shifting, and allow fine-tuning to avoid chain rasp, which is particularly important for "cross-over" riding.

Abstract: A shifting device including first and second shift control members, a takeup element, a holding member, and a release member. The takeup element configured for winding and unwinding a tensioned control cable. The first control member is rotatable about a handlebar and configured to rotate the takeup to at least pull or wind the control cable onto the takeup. The second control member is a return-to-neutral member for rotating the takeup to release the. The holding member is rotatable with the takeup and retains the takeup in select angular positions. The release member is operable for disengaging the holding member in response to the actuation or return stroke of the second control member for allowing the takeup to unwind the cable a sufficient amount to enable a single gear shift.

Abstract: A parallelogram link mechanism of a bicycle derailleur has a coil spring tensioned from a first axis of the parallelogram to another axis thereof that is diametrically opposed to the first axis. The coil spring exerts a primary spring force against the rider-supplied derailleur actuation force throughout the actuation range of the derailleur. A secondary member exerts a secondary force throughout a portion of the actuation range of the derailleur, producing a substantially constant resultant actuation force experienced by the rider. The secondary member can take various forms, including an abutment member which selectively abuts the coil spring at an angle to the spring axis; a second spring internal to the first; a member which is attached to spaced-apart coils of the coil spring to limit their linear expansion; and an internal member which limits constriction of a segment of the coil spring inwardly toward the spring axis.

Abstract: A gas spring suspension system that adjusts the spring rate as the travel is adjusted. The suspension system includes a frame, a pressure chamber, a compression piston assembly, an adjustment assembly, a piston tube, and a shaft. The piston tube is operatively connected to the adjustment assembly and the compression piston assembly, and the compression piston assembly is configured to slidably displace along the piston tube to change the pressure in the pressure chamber. The adjustment assembly is associated with the frame and is operable to axially position the piston tube and, in turn the compression piston assembly, relative to the frame to adjust the travel of the suspension system. The shaft is configured to be variably positionable within the pressure chamber in response to axial displacement of the piston tube and the compression piston assembly by the adjustment assembly, the variable positioning of the shaft within the pressure chamber changing the pressure therein.

Abstract: A suspension system that includes a simplified lockout mechanism and an adjustable blow-off mechanism. The system includes a valve mechanism and a valve actuating assembly, a valve mechanism housing and a resilient member disposed between the valve mechanism and the valve mechanism housing. The valve mechanism is slidably mounted along the valve mechanism housing and it separates a first chamber from a second chamber. The valve actuating assembly operates the valve mechanism between open and closed positions. The resilient member is configured to be deformable by the valve mechanism as the valve mechanism is slidably displaced by an increasing pressure in the first fluid chamber. The sliding valve mechanism is configured to collide against the valve actuating assembly when a blow-off pressure is reached in the first fluid chamber switching the valve mechanism from the closed position to the open position.

Abstract: A rotatable gripping surface for a derailleur-type bicycle gear shifting system is formed of a resilient material with axially extending alternating ribs and grooves. The ribs and grooves are spaced such that they fit naturally into the crooks of the rider's thumb and finger or fingers and the portion of the palm therebetween. The ribs provide an increased diameter to aid in the transmission of torque and to protrude above any mud which may have collected thereon. To further enhance the torque transmitting capabilities of the grip and the ability to remain effective in the presence of mud and other debris, the surfaces of the ribs are provided with a pattern of nubs. The hubs are engaged and deflected slightly by an operator's thumb and finger and the portion of the palm therebetween to transmit torque to the rotational grip. The deflection of the hubs as in the case of the ribs will provide for the transmission of torque in the presence of any debris such as mud which may be deposited on or between the nubs and the ribs and grooves.
