having threaded new cable wires, derailleurs and rear brake, through internal frame guides, ie bits of long thin plastic tubing I was told by shop selling frame to remove the guide tubing by pulling it through.
So now that the guide tubing has been removed how would I be able to replace an inner wire when required?
Whole idea of these internal wires seems a bit of a nonsense and from what I can see virtually impossible to do roadside repair on ??
