Abstract
A suspension system for the front wheel of a bicycle or motorcycle, which has a minimum amount of friction. The suspension system includes an upper and a lower swingarm, with a spring and elastomer combination, which works as a friction damper on the inside coils on the spring. The relative angle and length of the swingarm to one another, permits the linear movement of the wheel on impact, to optimize suspension performance. The invention also desirably incorporates various elements which provide for the structural rigidity of the suspension assembly and light weight. In particular, the design preferably incorporates standard bicycle or motorcycle components. For example such components may include wheels, brakes, axles and steering components.
