Patent number: 9829035Abstract: A bicycle control cable is provided with a central wire, an outer case and a radial protrusion. The central wire includes at least one metallic strand defining a radially outermost surface of the central wire. The outer case surrounds at least a portion of an axial length of the central wire. The outer case has a radially innermost surface. The radial protrusion spirally extends along one of either the radially outermost surface of the central wire or the radially innermost surface of the outer case in a direction intersecting with a center longitudinal axis of the bicycle control cable. The radial protrusion reduces a sliding resistance of the central wire relative to the outer case. The central wire is configured and arranged to slidably move in an axial direction with respect to the center longitudinal axis of the bicycle control cable within the outer case to operate a bicycle component.Type: GrantFiled: May 17, 2012Date of Patent: November 28, 2017Assignee: Shimano Inc.Inventors: Atsuhiro Nishimura, Kenji Ose, Takamoto Asakawa, Osamu Kariyama, Yoshimitsu Miki, Tooru Iwai
