unsure which
diameter to purchase.

IS there any guides as to which cables are for what
models or just get
the 1.2mm and call it a day.


Do not- and I cannot emphasize this strongly enough - DO
NOT install
not-Campagnolo wires into your Ergo shifters[1].

The gear wire heads of the classic era were small, as
Campagnolo uses
still. The revisionist modern larger gear wire heads
(everybody else who
makes gear systems) will go in, pop down inside the lever
and only come
out with extreme effort = time = $$$.


Lack of standardization on such simple things often astounds
me. It shouldn't, because it's so common. But it still
astounds me.



Two gear wire heads - quelle horreur!

Regarding electric plugs, I can see how each nation was tinkering around
independently in the early 1900s when there was less travel and many
fewer electric appliances and users. Standardization was a fresh idea
and not so popular. I can see that by the time someone smacked their
forehead and said "Damn, we should have all used the same system!" that
it was too late; the investments were made.

But for another example: I worked with industrial robots. Those
generally come with no end-of-arm tooling, because a major point of
robots is they can be used for such a wide variety of jobs (welding,
material handling, painting, etc. etc.) So they come with a round
flange on the "wrist" with a circle of bolt holes. You bolt the gripper
(or whatever) to that wrist.

One "True or False" question I commonly put on the exam was "The ANSI
standard wrist makes it easy to attach most grippers." False. There is
no ANSI standard wrist (or at least, there wasn't when I retired). Each
manufacturer comes up with their own wrist diameter, boss diameter,
number of tapped holes, etc. By the time this industry came into being,
everyone knew the benefits of standardization. Why make every company
machine its own adaptors?

And gear cable heads? Why say "Ours are going to be 0.1mm different"?
Do they really make that much profit by forcing people to buy their own
brand's special cables?
