Abstract: A bicycle storage frame for storing fluids includes a hollow fluid-tight frame section having a wall structure and an internal fluid chamber and at least one liquid fill opening formed in the wall structure accessing the internal fluid chamber of the frame section. At least one gas fill valve extends through the wall structure to access the internal fluid chamber for inputting of pressurized gas into the frame section and at least one liquid release valve extends through the wall structure accessing the internal fluid chamber for release of liquid held within the frame section. At least one gas release valve extends through the wall structure accessing the internal fluid chamber for releasing pressurized gas from within the frame structure and a gas transfer device such as an air chuck is connected to the gas release valve externally of the frame section for transferring gas from within the internal fluid chamber to a tire for inflation thereof.

Abstract: In combination, a bicycle having a frame and front and rear wheels and a bicycle gearing system which includes a movable bottom bracket mounted on the frame of the bicycle. A pedal axle is rotatably mounted in the bottom bracket. A chain extends between the front gear sprocket and a selected one of the rear gear sprockets. A rear derailleur is mounted on the frame generally adjacent and forward of the rear gear sprockets, the rear derailleur operative to engage the chain and shift the chain transversely relative to the frame. The chain is of a size and shape such that when the bottom bracket is in a forward position, the chain is tensioned, and when the bottom bracket is in the rearward position, the chain is detensioned. The chain is detensioned and the rear derailleur shifts the chain transversely relative to the frame such that the chain engages a different selected one of the rear gear sprockets.
