ABSTRACT:
A resilient suspension system for the front wheel of a bicycle or the like which turns bump energy into viscous heat loss without absorbing the pedaling energy of the rider. The suspension system includes two telescoping tubes having fluid therein and a fluid valve that meters the fluid flowing between the two tubes on the compression and expansion of the tubes. The invention also employs certain design features so as to retain the structural rigidity of the front fork assembly while remaining light in weight and utilizing a majority of the standard bicycle wheel, brake and steering components.
