ABSTRACT:
A bicycle shift operating device is provided that includes a first shift operating member, a second shift operating member and a transmission control mechanism. The first shift operating member is pivotally coupled to a first pivot axle for rotation about a first pivot axis to move along a first shifting plane that is perpendicular to the first pivot axis. The second shift operating member is pivotally coupled to a second pivot axle for rotation about a second pivot axis to move along a second shifting plane that is perpendicular to the second pivot axis and intersects the first shifting plane to form an angle equal to or less than about thirty degrees between the first and second shifting planes. The transmission control mechanism is configured to control a bicycle transmission. The transmission control mechanism is operatively coupled to the first and second shift operating members.
