ABSTRACT:
The headset of a conventional mountain bicycle is modified to permit the load supported by the front wheel to be transferred to the bicycle frame through a column of compressed air to minimize shock and vibration to the rider when riding over rough ground. A valve matching those in the mountain bicycle tires is located on the steering axis above the handle bar stem and permits the compressed air pressure to be adjusted for different rider weights through use of a conventional bicycle pump. The typical air pressure required with the shock absorber unloaded is less than the tire pressure. The shock absorber design should permit hard use for long periods without maintenance.
