A normally closed port valve seals a hydraulic hose connection port of a hydraulic bicycle component. Connection of an end of a hydraulic hose assembly (104) to the port opens the valve (236) , placing the assembly's hydraulic fluid chamber in fluid communication with the interior of the hose assembly. A hydraulic cylinder (200) of the assembly is in fluid communication with the chamber. A spring (222) may be used to bias the valve to a closed condition and simultaneously to bias a brake actuating piston (206) to a non-actuated position.
