I received a rear wheel from a Racing Zero bike that a customer brought in.

There was a bent spoke, so I attempted to true the wheel


but it turned out a spoke had become twisted.


I fixed it.


There are two spokes marked with tape,
but I only replaced one of them.
With the other one, there was a suspicion that "once I release the tension, it might reveal that it's bent,"
so I loosened it for now.
As for the spoke I didn't replace, the nipple had extremely high rotational resistance,
and I was concerned that I might twist the spoke (or worst case, snap it) myself,
so I replaced just the nipple with a new one.

I didn't intend to straighten out the twist,
but when I held the flattened section with a tool and turned the nipple,
it pretty much returned to normal.
But I won't reuse it—that's too risky.



Anyway, beyond all that, the customer had caused deformation stemming from impact marks on the hub side—which was the trigger for turning the nipple in the first place—
so replacement is essential either way.
