Abstract: In a preferred embodiment, an ultra-light weight suspension fork for bicycles that provides smooth action of the suspension system that hitherto has been unachievable. This fork assembly contains a telescoping mechanism located in the head tube of the bicycle that uses linear roller bearings to reduce stiction and prevent torsional losses, but limits weight by only using two such bearings. Side-to-side load is eliminated by the use of two longitudinal members in close proximity to the inner tube of this telescoping mechanism. The telescoping mechanism is coupled to the wheel via an arched single-sided fork crown designed to maintain torsional and braking stiffness. The arched crown contains arches in two dimensions. The fork crown is coupled to the wheel via a shaped fork tube whose wall is thickened while the outside diameter is reduced so that the connection point to the axle mechanism has the same outside diameter as the fork tube thereby enabling significant strengthening of the assembly.

Abstract: In a preferred embodiment, a light weight telescoping suspension seat mechanism for a watercraft seat pedestal designed to fit into an existing or new seat pedestal. This suspension seat mechanism contains a combination of roller bearings to allow the seat pedestal to move linearly, but not rotationally. An expanding bushing mechanism secures the seat assembly rigidly to the seat pedestal and floor, and another bushing connects the mechanism to the seat. Each are easily adjusted to allow for easy installation and removal of the suspension seat mechanism. Located inside the telescoping mechanism is a suspension damper with air rebound spring allowing the individual to tailor the suspension stiffness to individual preference. This suspension mechanism provides damping force on the seat. The rebound spring responds to seat movement so as to return the seat to its original position.

Abstract: An improved, lightweight suspension fork for a bicycle with variable travel capability that maintains excellent torsional rigidity. This suspension fork allows for adjustable suspension travel adjusted at the handlebars of the bicycle. The suspension system includes a travel adjustment knob located at the handlebars of the bicycle. The travel adjustment knob is keyed with the main shaft of the suspension system so as to allow turning of the main shaft. Located on the main shaft within the suspension system housing is a length adjuster mechanism. The length adjuster moves linearly with respect to the housing as the main shaft is turned pulling the inner tube member of the suspension housing up or down relative to the outer tube section of the suspension housing, thereby changing the stroke of the suspension system.
