Abstract

A bicycle control cable is provided with a central wire and a radial protrusion. The central wire includes at least one metallic strand defining a radially outermost surface of the central wire. The radial protrusion extends along the radially outermost surface in a direction intersecting with a center longitudinal axis of the central wire. The radial protrusion reduces a sliding resistance of the central wire. The central wire and the radial protrusion are configured and arranged to slidably move in an axial direction with respect to the center longitudinal axis of the central wire within an outer case to operate a bicycle component.

         6 . The bicycle control cable according to  claim 5 , wherein
 the fluorocarbon polymer is selected from a group consisting of perfluoroalkoxy, fluoroethylene-propylene and polytetraftuoroethylene.   
     
     
         7 . The bicycle control cable according to  claim 2 , wherein
 the at least one resin string is made of an olefin polymer.   
     
     
         8 . The bicycle control cable according to  claim 7 , wherein
 the olefin polymer is selected from a group consisting of polyethylene and polyacetal.   
     
     
         9 . The bicycle control cable according to  claim 2 , wherein
 the at least one resin string is made of polyethylene terephthalate.   
     
     
         10 . The bicycle control cable according to  claim 2 , wherein
 the at least one resin string has a diameter that is smaller than a diameter of the at least one metallic strand.   
     
     
         11 . The bicycle control cable according to  claim 2 , wherein
 the at least one resin string has a diameter that is larger than a diameter of the at least one metallic strand.   
     
     
         12 . The bicycle control cable according to  claim 1 , wherein
 the radial protrusion includes at least one metallic wire that is coated with solid lubricant and that is spirally wound around the central wire.   
     
     
         13 . The bicycle control cable according to  claim 12 , wherein
 the at least one resin string has a pitch that is less than or equal to 1 millimeter.   
     
     
         14 . The bicycle control cable according to  claim 13 , wherein
 the pitch of the at least one resin string is less than or equal to 500 micrometers.   
     
     
         15 . The bicycle control cable according to  claim 12 , wherein
 the solid lubricant is made of fluorocarbon polymer.   
     
     
         16 . The bicycle control cable according to  claim 15 , wherein
