    Abstract: In accordance with a preferred embodiment, a front fork wheel suspension of a bicycle has two telescoping suspension assemblies, one on each leg of the front fork. Each of the suspension assemblies includes a pair of telescoping tubes having a hydraulic fluid and an airspace therein, as well as a spring-loaded valve which regulates the flow of hydraulic fluid between the two tubes of the telescoping assembly. To control the point at which the assemblies change from a rigid, locked condition, in which the valve plate is closed, to a shock absorbing, telescopically displaceable condition, in which the valve plate is open, an adjustor rod is provided by which the degree of precompression of the valve spring can be changed. Furthermore, in order to improve the rigidity of the fork, the cross member interconnecting the lower tubes of the suspension assemblies has a compound cross-sectional shape which goes from circular cross section at a U-bend portion into a rectangular cross section at straight, leg portions thereof.

    Abstract: A shock absorbing device may include a housing, a piston, and membrane. The housing may define space. The piston may move within the space to adjust a pressure of a gas in a main spring chamber to form a gas spring. The piston and the housing may partially define the main spring chamber within the space. The membrane may be positioned in the space. The housing and the membrane may define a secondary spring chamber within the space. The membrane may partially define the main spring chamber and may be sufficiently elastic such that when the piston adjusts the pressure of the gas in the main spring chamber, a force applied on the membrane by the gas in the main spring chamber changes and causes the membrane to selectively deform to adjust a pressure of gas in the secondary spring chamber to control a spring rate of the gas spring.

    Abstract: A trailing link multi-bar suspension assembly for a cycle having improved stability includes a first arm having a first side and a second side, a first arm fixed pivot and a first arm shock pivot, the first side and second side defining a wheel opening. A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has an inline configuration, a gas spring, a first shock mount, and a second shock mount, and the shock absorber is substantially located on the first side or second side of the wheel opening. A spring unit, has a gas spring comprising a spring body, a first spring mount and a second spring mount, and the spring unit is substantially located on the first side or second side of the wheel opening A wheel carrier has a wheel carrier first pivot and a wheel carrier second pivot spaced apart from one another, and a wheel mount that is adapted to be connected to a wheel. A control link has a control link floating pivot and a control link fixed pivot, the control link floating pivot being pivotably connected to the wheel carrier second pivot, and the control link fixed pivot being pivotably connected to the first arm control pivot.
