<p>A pressurized air supply system for providing pressurized air to an air powered derailleur (69, 71) of a bicycle (10) having a bicycle frame (14). The system comprises an air pumping mechanism (54) attached to the bicycle frame and adapted to supply pressurized air when actuated. Fluidly connected to the pumping mechanism and to the derailleur is a pressure reservoir (70) of the system. The pumping mechanism is attached to the bicycle frame such that the passage of the bicycle over uneven terrain facilitates the actuation of the pumping mechanism and resultant charging of the pressure reservoir with pressurized air.</p> |
