I think the problem is that the insert of the ferrule needs to be relatively snug, to prevent the cable from sitting at a strange angle (and therefore not allowing the cable to run smoothly through the stop when shifting). What seems so bizarre to me is that the manufacturer of the stop (Silva) didn't make the ferrules - only Campagnolo would have supplied them with the cables themselves. So where are all the 5mm Campagnolo ferrules? Did they ever make them? If so, where are they? If not, how did the people who owned frames with this particular chainstay stop make them work?
I've read more about this than I ever could have possibly wanted, and it seems as though simply using the cable outer on its own won't work, as over time the strands of the cable become damaged - or so a few people in a similar position have stated.
I found another shop selling ferrules here in Italy and I've asked them for some advice, but I think the last remaining solution might be to have someone create a ferrule on a lathe.
