Another wheel day (and so on).
My mentor (the racing one) had left a rear rim replacement with me.
It's been quite a while since I took it in,
but he called saying to come pick it up once I've got it built, so(haven't got it built yet)
I told him it would definitely be ready or nearly ready 30 minutes after his arrival,
so I got to work in a hurry,
and had it done in just over 30 minutes.
Since all 32 spokes combined (left and right) are custom-cut,
that's pretty good going.
The old rim was an Araya Prostaff 340, and
there's been suspicion that the rim was bent. My assessment agrees,
and there's actual runout that appears to stem from that,
so truing it wouldn't be impossible, but it'd be pointless.
The hub is a 7900 32-hole,
the spokes are stainless steel (non-magnetic) Shimano Starbright,
built in 15-gauge plain 6-cross pattern.
The spoke length is unusually short, but that's because my mentor built it himself.
Being in a rush and not reusing spokes or rims,
I cut the spokes to disassemble it, and you can see the rim is bent
without even needing to lay it on the glass straightedge.
The hub flange holes show two spoke pull marks,
so it looks like the rim has been swapped out a few times.
The replacement rim I had on hand turned out to be quite something,
a Mavic Reflex tubular
CD Ceramic.
CD refers to the deep gray hard anodize color, but
Ceramic refers to the black surface treatment on the brake zone.
Plus it's from an era with chemical formula laser etching.
I said Reflex tubular earlier, but
someone might say, "There's no WO Reflex rim!" And they'd be right—
but this existed before Open Pro was released.
For more details on that and the CD Ceramic(see here).
If he only has one of these rims,
it would make more sense to use it for the front,
so I considered suggesting he build the rear with an Open Pro tubular (the current Reflex in name only)
and keep this rim safely(or give it to me),
but it does have rim cement marks even though it's not bent,
so it's not new.
So I went ahead and built the rear wheel as he wanted.
It's built.
FH-7900 hub, 32-hole, 4-cross Italian pattern.
I asked if he wanted spoke tension balancing,
and he said "no" as expected,
but I was prepared for that, so
I used semi-championship spokes instead of semi-competition. Hehehehe.
