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. The suspension system also includes a compression elastomer assembly positioned between a first end of the inner tube and the compression flange of the compression rod to provide a compressive damping force when the outer and inner tubes are compressed from a balanced condition, a rebound elastomer assembly positioned between the rebound flange of the compression rod and an opposite second end of the inner tube to provide a rebound damping force when the outer and inner tubes are extended from the balanced condition, and a second stage elastomer assembly positioned between the second end of the inner tube and the positive stop clip to provide a secondary compressive damping force when the inner tube crushes into the outer tube. An adjuster assembly is further provided to fine-tune the preload on the compression elastomers. The present invention also provides a method of quick conversion between standard and long travel configurations by modifying the configurations of the compression and rebound elastomer assemblies correspondingly.
