ABSTRACT:
A fork capable of absorbing the vibrations produced by the irregularities of the ground where a bicycle travels. In this way, vibrations do not end up being transmitted to the bicyclist's hands and arms, which is an advantage over conventional bicycles having rigid forks. The fork includes in each one of its two vertical arms or branches a shock absorber that comprises a group of elements that operates by means of oil and a gaseous fluid. Located between these elements is a floating piston that separates an oil chamber from the other gaseous fluid chamber. The fork includes a mechanical blocking system whose structure and functioning are very simple.
