Abstract: A bicycle control device is configured with an operating member that selectively controls a braking unit and a shifting such that shifting and braking can be easily performed while braking. The operating member has a user engagement part and a wire connecting portion with a support structure pivotally coupled to the user engagement part and a wire attachment member movably coupled to the support structure by a universal coupling. Also the operating member can perform a braking operation without movement of the main parts of the shifting unit. The shifting unit is movably disposed around a center shifting axis to provide a compact structure. The shifting unit has a position control mechanism that is configured to operate a positioning member that moves through two of a plurality of predetermined shift positions during a single progressive movement of the operating member.

Abstract: A hydraulic gear shift mechanism for a bicycle having a positioning mechanism for controlling the motion of the piston of a master cylinder assembly is disclosed, wherein the master cylinder assembly is in communication with a slave cylinder for operation of a derailleur. The positioning mechanism preferably includes a pivot shaft spaced apart from the handlebar, a rotating member rotatable about the pivot shaft, a push mechanism for rotating the rotating member in a first direction and a return mechanism for rotating the rotating member in a second direction. In a more preferred embodiment of the invention, an adjuster piston is threadingly engaged with the master cylinder assembly for adjusting the initial position of the slave cylinder.
