Another day of wheel building (and so on).
Building both front and rear wheels with the Nomu Lab Wheel No. 9's
55mm high rim
(claimed weight: 354g).
Next to the valve hole there's a rim hole with
a sticker arrow that says
"spoke direction goes this way"—
which is basically an instruction to "build it as a standard rim."
But if I just follow that,
is that all there is to it?
No, it isn't.
There's another, silent instruction separate from this.
Looking at the rim holes on both sides of the valve hole in the image above,
one hole is positioned roughly in the center,
but the other one is offset quite far outward.
↑Like this
This is the outer-side hole,
but when you actually check the inner-side hole,
the hole that's offset outward on the outer side
clearly shows spoke trajectory directivity
oriented outward from the wheel.
The rim hole offset outward on the outer side needs
spokes coming from the right flange on a front wheel, or the left flange on a rear wheel.
As I mentioned before, the arrow sticker only
instructs to "build it as a standard rim,"
so even following that,
you could still get the rim's left and right reversed.
However, the difference in hole offset between left and right on the rim
is a silent instruction,
so whether you notice it or not is—in a sense—being tested.
Today I built the front wheel with the heavier rim.
Revo disc hub, 24H, semi-CX sprint
64 reverse Italian lacing.
I'll do the truing later.
