Abstract: The present disclosure relates to a chain ring having teeth positioned in one of three lateral positions. At least one tooth may be placed in each lateral position. At least half the teeth may be positioned in a middle lateral position. The teeth in the first and third lateral positions may apply opposing lateral forces to a bicycle drive chain.

Abstract: A shock absorber includes a first portion and a second portion that reciprocate relative to one another. The shock absorber includes a gas spring chamber defined between an interior wall and a plunger. A seal including a lip portion minimizes gas pressure loss and friction between the two portions.

Abstract: The present disclosure relates to a rear shock absorber for a vehicle. The shock absorber may include a first end and a second end that slide telescopically relative to one another. A piston may be placed in fixed position relative to one of the ends. The first side of the piston may partially define a first chamber filled with a compressible fluid. The second side of the piston may partially define a second chamber filled with a substantially incompressible fluid. The substantially incompressible fluid may be under pressure and may lubricate a seal substantially surrounding a periphery of the piston.

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: A suspension unit for a front fork of a vehicle includes an annular tube. The first tube defines a compression chamber and a damping chamber. A damper includes a first valve allowing gas to variably flow from the compression chamber to the damping chamber and a second valve allowing gas to flow from the damping chamber to the compression chamber. An external adjuster allows a rider to adjust the first valve to improve ride conditions.

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: A shock absorber has a valve controlling the flow rate of fluid between a first chamber and a second chamber. The shock absorber may include a blocker that has a variable profile. The blocker may be rotatable using an external adjuster to position the blocker to variably occlude an aperture and vary the damping of the suspension. A bias may also be positioned adjacent the blocker to allow force from the fluid to move the blocker and expose the aperture, thereby allowing fluid to flow through the entirety of the aperture.

Abstract: A shock absorber having a valve controlling the flow rate of fluid between a compression chamber and a rebound chamber in a housing and separated by a piston. The valve has an orifice component and a blocker component, one of which has a permanent magnet, and the other of which has a magnetically permeable material. Upon the application of sufficient fluid pressure, the blocker component is forced away from the orifice component, despite the magnetic bias that tends to attract the two structures. Because the magnetic force decreases as the two components are spaced farther apart, the shock absorber has excellent performance characteristics. Alternatively, a mechanical spring urges the blocker closed, and magnetic attraction between the blocker and a spaced opener mitigates the increased force of the compressed spring tending to close the valve.

Abstract: A wheel assembly quick release lever pivots against a thrust washer to apply a force along the length of an axle. The thrust washer is pressed toward a sleeve nut at the opposite end of the axle, which displaces the thrust washer relative to the axle, drawing the sleeve nut and a pair of compression rings toward one another deeper into conical cavities of dropouts. The radially outwardly facing surfaces of the compression rings firmly seat against the tapered cavities of the closed bore dropouts, and the radially inwardly facing surfaces of the compression rings firmly seat against the axle to provide resistance to rotational movement of the axle relative to the dropouts. The inboard surfaces of the dropouts seat against the load-bearing axle faces of the hub, which provides resistance to lateral movement.

Abstract: A chain guide having a mounting bracket mounted to the bottom bracket shell with multiple coaxial pulleys, each of which is in substantially planar alignment with one chainring of a crank with two or more chainrings. Each pulley cog engages the bicycle chain when the chain is on a corresponding chainring. One of the pulley cogs can be replaced by a roller mounted to the bracket coaxially with the first pulley cog and in substantially planar alignment with the corresponding chainring.
