Abstract: A bicycle operating device comprises a base member, an operating member, and a hydraulic unit. The base member comprises a first end portion, a second end portion, and a gripping portion. The gripping portion is provided between the first end portion and the second end portion. The operating member is movably mounted to the base member from a rest position toward an operated position. The hydraulic unit is provided at one of the base member and the operating member. The hydraulic unit comprises a hydraulic cylinder and a piston. The hydraulic cylinder includes a cylinder bore. The piston is arranged in the cylinder bore. The piston is configured to be pulled from an initial position to an actuated position in response to a movement of the operating member from the rest position toward the operated position to supply a hydraulic pressure toward at least one bicycle component.

Abstract: A bicycle hydraulic quick-release apparatus comprises a main body and a hydraulic chamber. The main body includes a first hole and a second hole. The hydraulic chamber has a changeable volume and is provided between the first hole and the second hole. The hydraulic chamber is configured to be in a first chamber state where a volume of the hydraulic chamber is a first volume. The hydraulic chamber is configured to be in a second chamber state where the volume of the hydraulic chamber is a second volume different from the first volume. The hydraulic chamber is disconnected from the first hole in the second chamber state.

Abstract: A bicycle hydraulic operating device comprises a bracket, a hydraulic cylinder, a piston, a lever, a fluid reservoir, and a lid. The bracket is configured to be mounted to a bicycle handlebar. The piston is movably disposed within the hydraulic cylinder. The lever is pivotally provided around a pivot axis relative to the bracket and is operatively coupled to the piston to move the piston within the hydraulic cylinder in response to pivotal movement of the lever. The fluid reservoir is disposed on the bracket and having an opening configured to face substantially in a downward direction in a state where the bracket is mounted to the bicycle handlebar. The lid is configured to cover the opening of the fluid reservoir.

Abstract: A bicycle control device includes a housing member, a control lever member, a shift-operating mechanism and a hydraulic fluid pressure generator. The housing member has an attachment part for attachment to a handlebar, and a grip part extending longitudinally between first and second ends of the grip part. The shift-operating mechanism includes a cable take-up member rotatably mounted around a cable take-up axis. The cable take-up member has a control cable attachment part that is configured to be coupled to a shifting device by a control cable. The hydraulic fluid pressure generator has a cylinder and a piston movably that is disposed within the cylinder by movement of the control lever member to generate fluid pressure for controlling a braking device. The cylinder defines a cylinder axis that forms an angle of greater than or equal to 20° and less than or equal to 50° with the cable take-up axis.
