  • The focus of my question is towards mountain bikes, aimed to be used in the mud, and not of the lowest quality.

  • In the case of mountain bikes, the middle one you refer to is probably a brake hose, not a cable. You can't have an uninterrupted hydraulic brake hose :-)

  • @OllyHodgson, it is a brake cable on a Ferrini R3. Indeed, interrupted hoses would be fun.

  • Just for clarification: is your question about the cable housing (black tubes at the upper edge of your image) or about the thin transparent liner around two of the three cables? To me it looks like the answers given so far refer more to the housing than to the liners.

    Because the shifter cables require by far more precision which means they are more prone to friction. The Liner prevents water and dirt getting in and might also be teflon coated on the inside to make the cable glide more easily.
