摘要： A bicycle multi-gear cassette (10) mountable to a wheel hub that includes truncated conical shell (12) having a first opening proximate a small shell base and a second opening proximate a large shell base. The openings are coaxial with an axis of the shell. A plurality of toothed sprockets (14) having different numbers of teeth (48) are disposed on the shell and extend radially of the central axis. A torque load transmitting profile is configured on the shell proximate one of the small and large shell bases. A radial load transmitting profile (30,38,46) is configured on the shell proximate one of the small and large shell bases. The shell, sprockets, and the load transmitting profiles embody a single piece. The torque load transmitting profile forms a featureless contact surface for frictional engagement with the wheel hub.

摘要： A bicycle gear shifting system having rotatable front and rear handgrip shift actuators (408,410) operatively associated with control cables (415,417) for shifting respective front and rear derailleur mechanisms. A shifter rotator (412,413) drives a separate "jack spool" (436) which in turn actuates the control cable (415,417). A cam on the jack spool (436) is configured so as to substantially compensate for increasing force of the derailleur return spring during down-shifting. Compensation is provided in the shift actuator (408,410) for various lost motions in the derailleur shifting mechanisms and control cable systems. The shift actuator (408,410) also provides 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 actuator (408,410) also provides 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.

摘要： A twist grip cable system (10), optionally including a mandrel (20) is received over the handlebar (12) of a bicycle. A variable radius spool (72) may be provided, which gives a mechanical advantage which varies as a rotatable member (18) is rotated. To provide even greater mechanical advantage, with the spool (72) completely dropped away, a groove or slot is provided in the mandrel (20) into which the cable (66) may fall.

摘要： A bicycle shifter (10) for pulling and releasing a control cable (11) connected to a gear change mechanism that includes a housing mountable to a handlebar, a takeup member, a control member, a holding mechanism and a release mechanism. The takeup member is movable for pulling the control cable (11) in a cable-pull direction and releasing the control cable (11) in a cable-release direction. The control member is movable in a shift direction from a rest position for a first shift movement to permit motion of the takeup member in the cable-release direction. The first shift movement corresponds to a single gear change. The control member is moveable in the shift direction from the rest position for a second shift movement to move the takeup member in the cable-pull direction. The second shift movement corresponds to one or more gear changes. The second shift movement is greater than the first shift movement. The control member is biased toward the rest position. The holding mechanism retains the takeup member in a selected gear position. The drive mechanism is operable for releasing the holding mechanism from the takeup member and for moving the takeup member in response to actuation of the control member.

摘要： A gas spring suspension system that adjusts the spring rate as the travel is adjusted. The suspension system includes a frame (20), a pressure chamber (34), a compression piston assembly (32), an adjustment assembly (36), a piston tube (30), and a probe (64). The piston tube (30) is operatively connected to the adjustment assembly (36) and the compression piston assembly (32), and the piston assembly (32) is configured to slidably displace along the piston tube (30) to change the pressure in the pressure chamber (34). The adjustment assembly (36) is associated with the frame (20) and is operable to axially position the piston tube (30) and, in turn the piston assembly (32), relative to the frame (20) to adjust the travel of the suspension system. The probe (64) is configured to be variably positionable within the chamber (34) in response to axial displacement of the piston tube (30) and the piston assembly (32) by the adjustment assembly (36), the variable positioning of the probe (64) within the pressure chamber (34) changing the pressure therein.

摘要： A bicycle suspension system that includes an indicator for displaying the travel of a bicycle suspension system in response to an applied load. The system includes an inner tube telescopically engaging with the outer tube along an axis. A biasing mechanism biases the inner and outer tube apart from each other along the axis. The indicator is disposed along a length of the inner and outer tubes. The indicator may include a plurality of markings on the inner tube and a pointer on the outer tube. Each marking corresponds to a distance that the inner and outer tubes may be displaced relative to each other. The suspension system may include an adjustment mechanism that adjusts the distance the inner and outer tubes may be displaced relative to each other in response to an applied load. The rider may select the desired travel by actuating the adjustment mechanism to align the marking corresponding to the desired travel with the pointer. The indicator allows the rider to easily determine and select the travel of the suspension system without having to use a separate measuring device.

摘要： A rotatable handgrip twistshifter (10) mountable coaxially about a bicycle handlebar (20) that abruptly or discontinuously increases the mechanical advantage when shifting a front derailleur from a smaller to a larger chainring. A control cable (86) is slidably connected to the handgrip (12) such that during rotation of the handgrip (12) to effect gear shifts from the middle to larger chainrings of a triple chainring crankshaft (40, 41, 42), the cable (86) is abruptly dropped toward the handgrip axis of rotation thereby increasing the mechanical advantage or leverage of the shifter (10). Alternatively, the control cable (86) is slidably connected to the pivot arm (114) of a front derailleur such that during rotation of the handgrip (12) the cable (86) is deflected away from the derailleur pivot axis (207), likewise, increasing the mechanical advantage of the derailleur.

摘要： A brake or clutch operating device having a hand lever (24) pivotally attached to a mounting bracket (20) secured to a handlebar, the hand lever rotatable about a rotation axis (B) that is offset from the pivot axis (A), and a transmission mechanism (30) for converting a rotational force applied to the hand lever into a rectilinear force drawing the hand lever toward the handlebar. The transmission mechanism and hand lever configured to force rotation about the rotation axis in response to rotation of the hand lever about the pivot axis, the resulting compound motion of the hand lever following the natural arched motion of the rider's fingers during lever actuation.
