Another day of wheel building (and so on).
I built wheels using front and rear rims from the Smart Envi System 2.2 and
Crisking R45 hubs.
It might look like only the rear rim has a yellow sticker on it, but
the reason is that, taking the valve hole sticker's "Handmade in USA" side
as the right side (the other side has the serial number marking),
the yellow sticker (which also has a serial number and should be removed before use)
is positioned on the right side of the rear rim and the left side of the front rim.
Other than the requirement that "spokes should be black," I've been given free rein on the specs.
The front wheel is built with an R45 hub, 20H, black CX-RAY spokes, radial lacing,
and the rear wheel is built with an R45 hub, 24H, black with a half-Compé four-cross pattern.
I'll do the dishing later.
Since it's a very recent model, the braking surface has
the file finish we've discussed before (→here).
Regarding the linked SES 4.5, there was an issue with a nipple that bent, but
I never got around to writing about it. Though it's unrelated to this build,
I'll mention it while I'm at it.
The nipples that come with current Smart Envi rims are the fourth generation of internal nipples
counting from the EDGE era, and there's one spot where a center punch mark is made
(it doesn't look like a drill mark). As you hand-thread the spoke in, the resistance changes
right under where the punch mark is, so it's clear that this slight deformation
creates a loosening-resistant effect. After that point, the nipple can be turned with tools,
but it's impossible to thread the spoke through by hand.
The nipple in the image above appears to be one where this processing went wrong.
With hand strength plus tools like pliers, you can't deform a brass nipple like this,
so an enormous amount of force was applied. The number of nipples that come with the rim
matches the number of holes exactly, but we have a decent stock of spare nipples,
so we managed to work around it.
With current Smart Envi rims, warranty coverage requires both
"using genuine brake shoes" and "using the nipples that came with the rim," so
even though I'm not fond of these nipples
I have no choice but to use them.
Getting back to these wheels, the customer asked me to
weigh the completed wheels. I've also weighed the rims individually,
so I'll include those figures as well.

I should mention—these are tubular rims.
