A brake cable includes joining member including a hollow body having external threads, an externally extended rim at an end, and a channel through the body; a fastening member including an internal space having internal threads, a hollow extension extending out of a first end, a tunnel through the extension to communicate with the space, and an annular surface on a first end of the space adjacent to the extension; a sealing assembly urged against the annular surface; a cable assembly including a flexible sleeve having an outer annular flange; and an oil tube having a first end secured to the extension. The cable assembly is through the oil tube. Both the joining member and the fastening member are configured to compress the sealing assembly so as to urge the sealing assembly against the annular surface for preventing lubricant from leaking.

A bicycle control cable is provided with a central wire and at least one resin string. The at least one string made of resin is spirally wound onto the radially outermost surface in a direction intersecting with a center longitudinal axis of the central wire with a pitch less than or equal to 1 millimeter. The at least one resin string defines a spiral gap between adjacent windings of the at least one resin string. The at least one resin string defines an outer sliding surface for reducing a sliding resistance of the central wire. The central wire and the at least one resin string define an inner wire configured 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.
