  • Patent number: 5509677
    Abstract: A bicycle fork for interconnecting a bicycle wheel to a bicycle frame. The bicycle fork includes two leg assemblies, each having first and second leg members slidably engaged with each other, an elastomer for providing a biasing force when the leg members are compressed toward each other, and a fluid-based damping mechanism for providing a fluid-based damping force to resist relative movement of the leg members. The damping mechanism in one of the fork leg assemblies provides the primary compressive, fluid-based damping characteristics for the fork, while the damping mechanism in the other fork leg assembly provides the primary expansive, fluid-based damping characteristics for the fork. Each of these damping mechanisms may be adjusted without disassembling the fork to vary the damping characteristics as desired.

  • Patent number: 5470090
    Abstract: The present invention is a precision suspension fork for bicycles. The fork utilizes a telescoping suspension system for each of its fork legs. The telescoping suspension system includes an outer tube, an inner tube slidably engaged with the outer tube, and a compression rod slidably engaged with the inner tube. The compression rod has a compression flange and a spaced apart rebound flange at a first end, and a positive stop clip at a location adjacent to, but spaced apart from an opposite second end.

  • Patent number: 5445401
    Abstract: A bicycle fork for interconnecting a bicycle wheel to a bicycle frame. The bicycle fork includes first and second leg members slidably engaged with each other, an elastomer spring for providing a biasing force when the leg members are compressed toward each other, and a damping mechanism for providing a damping force to resist relative movement of the leg members. The damping mechanism provides expansive damping greater than compressive damping and further allows for adjustment of the expansive damping to fine tune the suspension characteristics of the bicycle fork.
