Another day of wheel building (and so on).
I received a Light Bicycle carbon rim from a customer.
It's a tubeless-ready rim with a depth of 45.3mm (measured).
Next to the valve hole there's a rim hole with
a sticker that says "assemble spokes this direction,"
and following it results in a proper (non-offset) rim configuration.
Alternatively, following the hole alignment itself
also results in a proper rim configuration.
I also received the hub.
It's a Prime R0020 model (right side in the image above),
and since Prime makes a road disc hub with model number RD0020,
this one without the "D" is for rim brake use without a disc mount.
The hub on the left in the image above is an Evolite hub,
but both are Novatec 482-series hubs
that are essentially identical except for freewheel body specs and hub body finishing.
The flange lightening and the stamping of the "24H" marking—
they're identical right down to the wear on the stamp.
On the outer edge of the rim there's a sticker saying "assemble with the freewheel side (right side) facing this direction,"
but this rim isn't left-right asymmetrical front or rear,
nor are the rim holes offset.
By the way, rims do exist where the rim profile itself is left-right asymmetrical
but the hole positions are centered (aside from hole alignment) (→here).
This sticker is round in shape and
isn't necessarily applied perpendicular to the rim's front-rear direction,
so
to strictly follow the instructions,
I twisted the hub orientation during the loose pre-assembly phase.
Once tension is applied (once the wheel is finished), the hub axle orientation ends up
perpendicular to the rim's front-rear direction.
Joking aside, I think labels like this should be rectangular
to avoid any mistakes.
This rim has no offset, and I don't see any directional difference
in the rim hole angles, so there must be another reason
for having this kind of instruction.

This rim has machining on the brake zone,
and the groove pattern has left-right attributes.
That alone would be fine, but the shape of this machining
looks remarkably similar to ZIPP's rim's "Show Stopper" (→here),
so I'm wondering if they'll get away with it if someone notices.
Built.
R0020 hub, 24H, black half-comp, 4-cross lacing, and
the nipples are basically silver,
with an Arcenciel nipple opposite the valve.
I'll do the truing later.
