Patent number: 8720301Abstract: A bicycle operating device includes a control member, first and second user operating members, a pivoting member and a transmission. The control member is rotated by actuation of the user operating members to control a control cable. The first user operating member rotates the control member in a first direction as the first user operating member rotates along a first motion plane. The second user operating member rotates the control member in a second direction as the second user operating member rotates along a second motion plane. The first and second motion planes form an angle in a range of twenty degrees to seventy degrees. The pivoting member pivots about a pivot axis that is offset from the operating axes of the user operating members to control movement of the control member by the transmission in response to the first user operating member being operated.Type: GrantFiled: February 24, 2012Date of Patent: May 13, 2014Assignee: Shimano Inc.Inventors: Tatsuya Kawakami, Yoshimitsu Miki, Kazutaka Fukao, Takafumi Nishino
