Hillrider, I respectifully disagree. On this thread, there are examples of different experiences and outright false information.

A couple of people described using cables that were not designed for use with Campagnolo with Campagnolo brifters, with mixed success. That's useful information, and I have no beef with that (even though it wasn't exactly what I was asking about). I wouldn't want to try that, even if it does work for some people.

I was simply asking if Campagnolo-brand cables are the only ones that will work, or if other brands exist that will also work. Maybe I should have been clearer, but my question really is "does anyone besides Campagnolo make cables which are 100% intended to work with Campagnolo brifters". It seems trivial to me that no cable manufacturer would bother to make a cable with a nub on the end that fits specifically in a Campagnolo brifter. Yet several people answered my question with a definitive and unequivocal NO.

For example, Fixer said that I had to use Campagnolo, and yet he hadn't heard of dual-ended derailleur cables. I now know that they do exist. Therefore, Fixer gave me advice about something he didn't know all the facts about. I know he meant well, but honestly he probably should not have said anything at all.

Mactheknife said the same thing: that I have to buy Campy. But he then proceeded to demonstrate that he, too, had not heard of the existence of double-ended cables. Again, he should probably have said nothing at all.

I didn't mean to suggest that anyone was deliberately distributing misinformation. Obviously Fixer and Mactheknife both meant well, and it's perhaps perfectly understandable that neither of them would have known about the double ended cables. Still, they should have looked at my question, asked themselves if they really knew whether generic-branded-but-designed-for-campagnolo cables existed or not, concluded that they did not know, and then moved on.

As for the people who are using Shimano-style cables in Campagnolo brifters, I did not intend at all to suggest that they were the ones being misleading. Clearly they were simply describing their personal experience with a hardware "hack". It's the people who made flat-out incorrect statements that I take issue with.
