Built a wheel with a 50mm tubeless-ready rim (front wheel, part 1)

Another day on wheels (et cetera).

Built a front wheel with a 50mm tall tubeless-ready rim.

Extralite Cyberfront front hub
20H black CX-RAY outpoke radial laced
with black aluminum nipples.
"Cyberfront" is where the hub name ends,
so I wrote it as Cyberfront front hub.

As for this rim, the 50mm height is fine,
but it's quite a wide rim with an external width of 30mm and internal width of 22mm.
It's not a hookless rim, but if it were hookless
the internal width would probably be around 25mm.
Considering that, it's a seriously lightweight rim.
If the hub weren't an Extralite and the rim were heavier,
I might have built it with CX-Sprint instead of CX-RAY,
prioritizing stiffness over everything else.

Following the Extralite front hub's standard instruction—
"the side with the bearing cone-race adjustment nut goes on the left"—
the lettering on the hub shell ends up reversed
compared to most other front hubs out there.

You might ask: does a radial-laced, unlabeled rim with no name have directional properties?

And the answer is yes—this rim has directional properties because the brake zone
features a groove pattern that's mirrored differently on the left and right sides.
