Bicycle pump, characterized in that the tubular cylindrical body that is constituted in the pump chamber, shelters a tubular cylindrical piston, in whose front end a piece is inserted that offers a threaded axial hole and a base in which, previously, fixed by a screw, sits a lining of. Leather that affects the shape of a cup, whose edges are imprinted against the inner contour of the aforementioned chamber, settling on the back of the indicated base, the end of a coil spring that is wound around the plunger, which passes through a hole axially provided in a plug that is threaded at the rear end of the cylindrical body that makes up the compression chamber of the pump, while, previously, said body has coupled a cylindrical piece traversed axially by a hole that is in continuous communication with the hole provided by a threaded outer contour mouthpiece, said joint integral with said cylindrical part, an elastic joint being arranged around the nozzle, while a removable tubular cylindrical lining is fitted on the outer contour of the tubular body of the casing, the base of which it has a quadrangular hole designed to give way to a stepped ledge likewise, which is configured in a threaded in the aforementioned nozzle.
