A customer brought in a Racing Zero rear wheel for repair.
The very first original Racing Zero, including color specification,
has a rim/spokes/hub all in red,
but this black/red/black is a later color variant with the same construction as the original otherwise.
The rear derailleur got caught in it, and
all 7 spokes on the porcupine side (outer spokes)
are broken.
The first impact seems to be from this spoke.
There was one spoke on the opposite porcupine side that looked bent,
but it wasn't actually deformed—
the hub had twisted slightly in the rotation direction,
which just made the spoke bow-shaped.
I've fixed it.
I'm ordering red tie-on spokes as I don't have enough stock.
The original Racing Zero's red spokes come in two different lengths:
R0F-SR (Racing Zero Front-Spoke Red) and
R0R-SR (Racing Zero Rear-Spoke Red).
The rear wheel having the same spoke length on both sides isn't by coincidence of course—
it's designed with such high-low flange geometry.
Shimano's first complete wheel, the WH-7700, did the same thing,
but with the WH-7701, they switched to radial lacing on the freewheel side,
so spoke lengths became three types: front, rear right, and rear left.
As for single-spoke packaging, it used to come in flat envelope-style bags,
but now it arrives in boxes the same size as the front 16-spoke sets or rear 21-spoke sets.
This is more convenient for keeping the same spokes together.
Come to think of it, there was that shitty shop incident from way back where they ordered red aluminum spokes from Fulcrum and forced me to buy them saying "since we ordered them, you have to buy them" (→here),
but if that hadn't happened, this red tie-on spoke repair wouldn't have meant
the customer had to wait while I ordered the spokes.
On rear hubs before the mega high-low flange era, replacing inner spokes requires
temporarily removing the outer spokes that overlap at the first crossing.
But this time only the outer spokes were bad,
so I didn't have to go through that hassle.

The first impact shows major deformation, but
the other spokes aren't, so I asked the customer if they'd cut it with pliers or something,
but they said they hadn't touched anything in particular.
Talking with them when picking it up, apparently a nearby shop said
the rim has impact damage so needs replacement, and all spokes need replacing too,
so it would cost 50,000-60,000 yen. Or just buy a new current model.
If they're getting that kind of money, they might as well say they'll do it.
Or if it's a trade-in for a current Racing Zero,
of course they'll just move it from right to left without any inspection, but even if not
they make easy profit.
Well, the fact that they brought it to our shop means we're trusted more than that place.
