Abstract
A resilient support device for installation on seat or wheel fork supports of light vehicles, such as bicycles or motorcycles, for the comfort of the rider. The invention achieves arbitrary and discretionary adjustment of support stiffness with a high degree of variability to accommodate riders over a wide range of weight and road conditions from mild to rough. Novel mechanical configurations are disclosed for ease of adjustment over the range of operation.
