An active air spring regulates and controls compression and rebound travel, speed, and shock position by modulating internal pressures in an air bag and/or air cylinder in real time by varying the internal volume of discrete air reservoirs in fluid connection with one another as controlled by valves, venting, and self-pressurization.

A dropper post may include an outer tube and an inner tube slidable relative to the outer tube between an extended position and a retracted position. A spring cartridge may include an axially extending cylinder containing a combination of a liquid and a gas and having a sliding surface and a piston with a sealing portion dividing the cylinder interior to provide a first chamber and a second chamber. Moving the inner tube toward the retracted position expands the first chamber. When inner tube is in the extended position the sealing portion is at least partially submerged in the liquid, the second chamber contains a layer of the gas above a layer of the liquid and the first chamber contains the liquid and when the inner tube is in the retracted position the first chamber contains the liquid and a layer of gas between the liquid and the sealing portion.

The integrated tank and compressor mounting system for a motorcycle has a mount block which has a mounting face, and a compressor clamp. The mount block has a threaded cylindrical section which forms a tank mount for mounting a tank. The tank has a cylindrical tubular section closed at one end and threaded at the other end such that the tank threads correspond to the mount block threads. The tank provides air for an air suspension which includes a forward suspension unit activated by air and an aft suspension unit activated by air. A supply line connects the tank air volume to an inlet valve on the suspension control unit. The suspension control unit has a cylindrical forward control valve passage and the forward control valve passage has a forward transfer chamber.

A hydraulic flow adjuster includes a first hydraulic tank, a second hydraulic tank, and a piston actuator. A first piston operates within the first hydraulic tank and a second piston operates within the second hydraulic tank. The piston actuator adjusts a relative position of the first piston in the first hydraulic tank and a relative position of the second piston position in the second hydraulic tank, such that the relative position of the first piston in the first hydraulic tank is the same as the relative position of the second piston in the second hydraulic tank.

A system and method for utilizing an active valve customizable tune application is disclosed. The system includes a mobile device having a memory, an active valve tune application, and at least one processor. The processor initiates the active valve tune application, receives, from a database, an active valve suspension tune having a number of performance range adjustable settings, and receives user related input information. At least one of the performance range adjustable settings is modified based on the received input information to generate a modified active valve suspension tune. The system includes an active suspension of a vehicle, wherein the modified active valve suspension tune is implemented by the active suspension.

Example bicycle suspension components and control devices are described herein. An example shock absorber includes a damper body defining a first chamber and a reservoir defining a second chamber. A flow path is defined between the first chamber and the second chamber. The example shock absorber also includes a flow control member disposed in the flow path and a motor to operate the flow control member to affect fluid flow between the first chamber and the second chamber.

In a suspension for a vehicle including a pre-load adjustment mechanism, the pre-load adjustment mechanism includes a pre-load controller and an intermediate member, the pre-load controller being arranged at one end portion and receiving a spring, the intermediate member being sandwiched between the pre-load controller and the spring, the pre-load controller fits in an outer circumferential portion of the one end portion and is movable in the stroke direction by turning on a thread portion of the outer circumferential portion, the one end portion includes a long groove portion in the outer circumferential portion, the long groove portion extending in the stroke direction, the intermediate member has a ring-shape and is movable in the stroke direction, the outer circumferential portion being inserted to the ring-shape, and the intermediate member includes an engagement portion that engages with the long groove portion.

The front fork of the present invention has a wheel-side bracket that closes another end of an inner tube which is movably inserted inside an outer tube from one end thereof; a cylinder provided inside the inner tube; and a head member that is fitted to the cylinder side on the opposite side from the wheel-side bracket, in which the cylinder and the head member are sandwiched, while subjected to an axial force, by a fastening portion formed on the inner tube and the wheel-side bracket.
