A customer brought in a rear wheel from a Shamal Mille for repair.
There was one noticeable lateral runout, and when they took it to a nearby shop,
they said they couldn't fix it.
The cause was a deformed spoke on the non-drive side.
At the point of the image above, not only was the tension released...
the spoke has already separated from the flange.
As for how this happened, they were adjusting the derailleur with the rear wheel spinning,
and a stand that clamps onto the hub quick-release came loose and
got caught on the left side of the rear wheel. Ouch.
But that's not really the issue here.
The two spokes on the drive side that neighbor the deformed spoke in the G3 pattern,
when someone tried to adjust their nipples,
the spokes were twisted.
It didn't come out well in the photo above, but
↑it looked like this.
I showed the customer that it was already this way before I touched it.
With these two drive-side nipples,
it's possible to eliminate the lateral runout
by adjusting them while the non-drive spoke remains bent.
But then you get radial runout.
Actually, I worked on a wheel like that the other day (→here).
However, as I mentioned at the start, there was lateral runout when they brought it in,
and from my assessment, there are no visible marks showing these nipples
were turned to any significant degree.
In other words, this shop "tried to turn the drive-side nipples,
twisted the spoke, couldn't fix it, and sent it back"—
and they didn't even tell the customer the spoke was twisted
(they didn't know until I pointed it out).
Either way, without replacing spokes,
even I can't fix this problem,
but a shop that can only manage this level of sloppy work
clearly isn't capable of making that judgment in the first place.
Fixed it.
Just adjusting the nipple on the replacement spoke got it nearly straight.
So as I suspected, I didn't turn those neighboring drive-side nipples.
I didn't replace the twisted spoke,
but I did straighten out some of the twist.

It wasn't just bent laterally,
it was also warped in the fore-aft direction.
