Another wheel day (and so on).
I've been holding onto a rear rim replacement for my mentor (the racing guy).
It's been quite a while since I took it in,
but he called to say if I could get it built, come pick it up, so(like I could get it done)
I told him that in about 30 minutes I'd have it done or nearly done when he comes in,
so I'd be fine—and rushed into the work.
Got it built in a little over 30 minutes.
All 32 spokes combined from both sides are hand-cut,
so considering that, pretty good going.
The rim being replaced was an Araya ProStaff 340,
and there was some suspicion the rim was warped—my assessment agrees.
There's actually runout that seems to stem from that,
so truing it isn't impossible, but it'd be pointless.
The hub is a 7900, 32H,
The spokes don't stick to a magnet—they're those cruddy Starbright ones—
15-gauge plain, built 6x lacing.
The spoke length is unusually short, but that's because my mentor built it himself.
Being in a hurry and not reusing spokes or rim, I cut the spokes and disassembled it.
Even without putting it on the glass straightedge, you can tell the rim is warped.
Looking at the hub flange holes, there are two stress marks from inpoke lacing,
so it looks like the rim's been swapped out multiple times.
The replacement rim I'd been holding turned out to be something wild:
A Mavic Reflexe tubular
CD Ceramic.
CD refers to the dark gray hard-anodized color finish, but
Ceramic refers to the black surface treatment on the brake zone.
And it's from the era with the chemical formula laser etching.
I said Reflexe tubular before, but someone might say, "There was no WO rim on Reflexe!"
and they'd have a point—but it did exist before Open Pro came out.
For details on that and the CD Ceramic(→see here).
If he only has one of this rim, it'd make more sense to use it as a front,
so I was thinking of suggesting he build the rear with an Open Pro tubular (aka the current Reflexe),
and keep this rim carefully.(Or give it to me.)
But since it shows rim cement marks even though it's not warped,
it's not brand new.
So I went ahead and built the rear wheel as requested.
Built.
FH-7900 hub, 32H, 4x Italian cross lacing.
I asked if he wanted spoke wrapping,
and predictably he said "No,"
but I'd anticipated that, so
I went with half-Champion instead of half-Competizione spokes. Hehehehe.
