Wheels again today (and so on).
I built a front wheel using the SES 3.4 front rim.
Building a "front wheel with a front rim" sounds obvious enough,
but Smart Envy Systems designates their front/rear rims as follows:
front rim is 20H only, rear rim is 24H.
The rims I received for this SES 3.4 project have the official model names
38AC and 42AC. Since the 42AC is designated as a rear rim,
it's not an offset rim and has no left/right specification,
so there might be people out there who build both front and rear wheels at 24H using the 42AC.
In that case, the expression "I built the front wheel with the SES 3.4 rear rim" would also be valid.
The reason ENVE rims can be tensioned to such extremely high tension
is partly due to the internal nipple design,
but more importantly, they don't drill rim holes into a holeless rim after the fact—
instead, the rim holes are molded into the mold shape beforehand,
so the rim already has its holes at the moment of completion.
This manufacturing method means that even for the same rim model, different spoke counts require different molds.
So SES and later rims have only one spoke count option per model,
a cost-focused specification.
Older "45" rims had 28H options, which were useful for cyclocross wheels and such,
but maybe they didn't sell well enough to recoup the mold costs through 20H and 24H sales alone.
White's black T11 hub, 20H, CX-RAY outpoke radial lacing,
with silver spokes flanking the valve hole on both sides and two more clockwise,
and black spokes for everything else.
A rim brake rim with file-finished braking surface,
a hooked carbon rim, not hookless,
with tubeless-ready spec.
…There's a lot to explain here.
Not so long ago, road bike rims meant only rim brakes,
there were no hookless rims, and tubeless-ready rims were almost nonexistent,
so I wouldn't have needed to write down all this information.
The stickers around the valve area read "Handmade in the USA" on both sides,
different from the version that doesn't have a serial number on one side.
The white sticker slightly to the side has
the serial number and barcode, and
the label embedded in the rim's outer edge also
shows the same serial number.
