Abstract: A hydraulic converter for a hydraulic brake system or clutch system, in particular, of a handlebar-steered vehicle, in particular of a bicycle, includes at least one hydraulic master device and a mechanical slave device for actuating the hydraulic master device. The hydraulic master device comprises a cylinder with a pressure chamber, a piston arranged in the cylinder displaceably along the axis of the cylinder, and the hydraulic converter having an adjustment device for adjusting the volume of the pressure chamber of the cylinder.

Abstract: A master for a hydraulic actuating element, with a cylinder, in which a piston is displaceably mounted, and a hand lever, with which the position of the piston in the cylinder can be influenced, and a fastening element which comprises a clamping part shaped complementarily to the inner cross section of the handlebar, which is equipped for being fastened in the handlebar by means of an internal clamping. Furthermore, the invention relates to a master, in which the hand lever and the piston are connected by a push rod, which comprises a first longitudinal portion, which is provided with an external thread, which engages in an internal thread on the hand lever, so that the distance between piston and hand lever can be adjusted by turning the push rod, and wherein the push rod comprises a second longitudinal portion, which is provided with a polygonal outer cross section, which bears against at least one second spring element.
