Abstract: A bicycle control device basically includes a housing member, a hydraulic fluid pressure generator, a control lever member and a shift-operating mechanism. The housing member has an attachment part for attachment to a handlebar, and a grip part configured to be gripped by a rider in a riding position. The hydraulic fluid pressure generator has a cylinder provided inside the grip part of the housing member, and a piston movably disposed within the cylinder to generate fluid pressure for controlling a braking device. The control lever member has a first operation lever pivotably coupled relative to the housing member for pivoting about a first axis to operate the piston. The shift-operating mechanism is configured to be coupled to a shifting device by a control cable control. The shift-operating mechanism is mounted on the control lever member.

Abstract: A bicycle operating device includes a base, a positioning ratchet, a positioning pawl, a user operated member, a first release member and a first release pawl. The positioning pawl engages the positioning ratchet to selectively maintain the positioning ratchet in first and second positions. The user operated member is in a first rest position while the positioning ratchet is in the first position, and in a second rest position while the positioning ratchet is in the second position. The positioning pawl is disengaged from the positioning ratchet by the first release member in response to the user operated member being operated from the second rest position in one of a first direction and a second direction. The first release pawl is provided on the user operated member, and contacts the first release member at the second position to maintain the user operated member at the second rest position.

Abstract: A bicycle operating device includes a base member, first and second cable control bodies, first and second positioning mechanisms, an operating member and an input mechanism. The first positioning mechanism selectively maintains the first cable control body in a first predetermined position. The second positioning mechanism selectively maintains the second cable control body in a second predetermined position. The input mechanism moves the first and second cable control bodies between the first and second predetermined positions in accordance with a predetermined operation sequence having a changing point to change operation from the first cable control body to the second cable control body. The input mechanism moves the first cable control body by at least two of the first predetermined positions in a single continuous operation of the operating member. The input mechanism includes a restricting structure that prohibits movement of the first cable control body at the changing point.

Abstract: A bicycle operating apparatus is provided with a base member, a ratchet, a pawl member and an operating member. The ratchet is rotatably disposed around a ratchet axis, and biased in a first direction about the ratchet axis. The operating member moves the pawl member from a first position to a second position. The pawl member has a pawl portion and first and second support portions. The pawl portion engages with the ratchet teeth while the pawl member is in the second position to regulate rotation of the ratchet in the first direction. The first support portion pivotally supports the pawl member around a first axis as the pawl member moves from the first position to the second position. The second support portion pivotally supports the pawl member around a second axis while the pawl member is in the second position.

Abstract: A bicycle operating device comprises a base, a user operated input, a cable actuator and a positioning abutment. The user operated input is movably arranged with respect to the base from a rest position towards an operated position. The cable actuator is movably arranged with respect to the base in response to movement of the user operated input between at least first and second cable holding positions. The positioning abutment is movably supported on the base between at least a first abutment position and a second abutment position. The positioning abutment selectively engages the user operated input to position the user operated input at an adjusted rest position in a state after the user operated input has been moved from the rest position to the operated position. The adjusted rest position is different from the rest position.

Abstract: A bicycle operating device includes a support structure, a release member, a positioning ratchet and a position maintaining pawl. The release member is movable between first and second positions. The positioning ratchet has positioning ratchet teeth that establish predetermined positions. The position maintaining pawl is movable between a ratchet maintaining position and a ratchet releasing position. The position maintaining pawl includes a positioning portion, a holding portion, a release portion and a contact portion. The positioning portion moves away from the positioning ratchet, while the contact portion and the holding portion move toward the positioning ratchet teeth as the release member contacts and moves the release portion away from the release member as the release member moves in a releasing direction. The release portion moves away from the release member in response to movement of the positioning ratchet contacting and moving the contact portion away from the positioning ratchet.

Abstract: A bicycle operating device basically includes an operating member and a click mechanism. The click mechanism includes an input part, an output part and an intermediate part. The intermediate part is movable between the input and output parts to transmit movement from the input part to the output part in accordance with movement of the operating member. The intermediate part contacts the input part at a first contact point, and contacts the output part at a second contact point. The intermediate part and the output part define a first angle that decreases as the operating member moves from the first position toward the second position. The first angle has an apex at the second contact point, a first leg extending from the second contact point to a center of the pivot of the output part and a second leg extending from the second contact point to the first contact point.
