This is a follow-up to my earlier post about American Classic's slitted spoke hole hub design（→here）.
I had written that the hub was limited to JIS or Italian lacing patterns,
but I received a comment correctly stating that "the slits actually restrict the direction
in which spokes can be tensioned
（porcupine direction・anti-porcupine direction）"
I apologize for my misunderstanding of the intent.
Regarding the "middle" lacing pattern section and
the frustration that bleeds through the text —
there are other circumstances, and it wasn't directed at the person who left that comment.
If I caused any offense, I sincerely apologize.
Since I maintain a policy of not deleting posts, I'll add cross-links
and address the correction in the original post.
Below is the actual verification.
A customer's wheel needs a relacing, so
I'll use that for this.
It's a 28H standard rim "middle" lacing, left-drop 4-cross Italian pattern.
I'm about to convert from Italian to JIS lacing,
but since it's 4-cross to 4-cross,
the "4-cross" detail is irrelevant information.
Since I'm not changing it to asymmetrical lacing, "28H" is also unnecessary information.
Also, I won't touch any spokes or nipples on the freewheel side.
Since the freewheel-side spokes remain fixed, the "standard rim" designation
doesn't change, so that information is unnecessary too.
I'll focus only on "left-drop Italian lacing."
Before relacing — it's Italian lacing.
I won't touch the freewheel side, so I didn't need to mark it, but
to show that there are slits where spokes shouldn't be tensioned,
I've marked them in blue.
I've similarly marked the drive-side flange in blue.
Currently, neither flange is tensioned toward the slit direction.
I've marked the N-spoke hole in red.
From here, if I disassemble only the drive side and
convert Italian lacing to JIS,
like I did before, the "middle" lacing becomes "center" lacing.
So on the drive side only, I flip the N-spoke and anti-N-spoke
（in other words, converting left-drop to right-drop）
and then apply JIS lacing.
I had a misconception about the part in red text.
I've converted to right-drop while applying JIS lacing.
The hole that was the N-spoke position is now anti-N-spoke, and it's JIS lacing.
And here's what I think is crucial — the "middle" lacing pattern is preserved.
To emphasize: the freewheel-side spokes and nipples haven't been touched and are in the same position.
I believe what was stated in the comment is exactly this. Am I correct?
Which means my earlier expression
that it's "limited to JIS or Italian lacing" was wrong,
and the correct expression is "the spoke tension direction is limited"
（though there are other ways to phrase it）.
Thank you for the correction.
Also, to the person who left a different comment that I haven't addressed here.
It's exactly "that," but I can't write about it here.
It's literally the bread and butter code.
While I appear to be dispensing wisdom, the truth is
I'm the one actually learning the most.
There probably aren't many bike shops that receive such valuable comments.
Finally. There's another person who might take offense at this verification,
but they're a competitor, so I won't play nice. Listen, "center" lacing ain't the answer, you hear.
