• I'm an idiot. It's DD turbo. Different cassette.

    Anyway, if cables have been rubbed through and you can see the outer sheath wires, would you swap them? Nothing broken and nothing sticking out but I wonder if they could rust through and then impede shifting a bit? I know there's an inner tube as well but I'm tempted to just get them swapped out before something goes south.

  • Replace. The plastic sheath holds the longitudinal gear cable casing strands in alignment. Without the plastic sheath’s restraint all the way round, you get excessive deflection and bad gear changes.

  • Good, that's what I'd told her but no one listens to me. Good to have confirmation. :)
