Lennard Zinn describes the causes and repair process for
removing broken cables from 11sp Ultegra ST-R8000 and 6800,
and various Dura-Ace levers.

cable-out
According to Lennard it's "an irritatingly common occurrence".
Maybe if they used special Campagnolo non-stretch shifter
cables it wouldn't be a problem?

Mr Zinn's right on that point.
Campagnolo Ergo wires stick one's palm as they start to fray, well
before failure. It's a very noticeable warning.

Which version/models/years are you referring to? I rode
Campagnolo Chorus 9Sp for many years, never had that
experience.

The wire path is on the outside and the capstan spools under the lever,
so fraying starts at the outside bottom of your palm and although not
painful it's noticeable.

Is that on the older 9sp stuff as well?

Yes, all 8, 9, 10 Ergos from 1992; same wire path.
The 11, 12, 13 speed (non rebuildable) Ergos have the same general
layout but the wire path is under a cover so now a fraying wire won't
stab the operator. A broken head still falls straight down, out of the shifter, rather than mangling the mechanism as with The Other brand.

That's interesting, I had Chorus 9sp on my commuter and race
rig for probably ten years. After I converted my race rig to
10sp I put the chorus setup on my cx bike (still there) and
raced it for a number of years. I've never had an issue with
fraying cables. Just luck I guess?
