Abstract: A shock absorber includes a compensator and a variable volume chamber. The compensator contains a compressible fluid and the variable volume chamber contains a substantially incompressible fluid. During a compression stroke, an increase in the volume of the incompressible fluid in the variable volume chamber compresses the compensator and thereby increases the available volume in the variable volume chamber.

Abstract: An assembly for minimizing the disengagement of a chain from a chain ring is disclosed. The assembly includes a bracket and a chain guide assembly. The chain guide assembly includes an inboard leg, an outboard leg, and a lock. The lock may be configured to allow a rider to remove the outboard leg of the chain guide assembly without tools.

Abstract: A drive system for a vehicle includes a chain ring and a drive chain. The chain ring has a plurality of teeth serially arranged and joined to one another. A first subset of teeth has a first outer face that applies a lateral pressure to a link of a drive chain in a first direction. A second subset of teeth has a second outer face that applies a lateral pressure to another link of a drive chain in a second direction. The teeth all have substantially the same width. The top surfaces of the teeth are offset from the centerline of the drive chain. The centerlines of the top surfaces of the teeth are arranged asymmetrically on one side of the centerline of the drive chain.

Abstract: An assembly for minimizing the disengagement of a chain from a chain ring is disclosed. The assembly includes a bracket and a chain guide assembly. The chain guide assembly includes a chain guide, a first lock and a second lock. The first lock and the second lock are capable of being actuated separately to lock the chain guide into a position in each of a first and second orientation relative to the bracket.

Abstract: A shock absorber includes a first end and a second end that reciprocate relative to one another. The shock absorber includes a gas spring chamber, a damping chamber, and a floating piston. The first side of the floating piston is in fluid communication with the gas spring chamber. The second side of the floating piston is in fluid communication with the damping chamber. The gas in the gas spring chamber applies pressure against the floating piston, which applies pressure to the substantially incompressible fluid in the damping chamber. This pressure transfer may be adequate to minimize or prevent cavitation.

Abstract: An assembly for minimizing the disengagement of a chain from a chain ring is disclosed. The assembly includes an inboard leg and an outboard leg. Rotation of the outboard leg relative to the inboard leg locks the inboard leg in place relative to the outboard leg. Relative rotation locks the assembly onto a shaft. The assembly may include an outboard leg that snaps into place on the inboard leg and is capable of rotating between two extreme positions.
