Another day of wheel work (and so on).
Continuing from yesterday.
I'm about to disassemble the front wheel with the Nemesis rim and 7900 hub, but first.
Normally when I post images here, I remove the tire and quick release,
but there's something I want to touch on, so this time I deliberately left them on.
The Miyata tubular tape broke midway through,
so I added more, but I forgot to peel off the release paper on the added portion (※).
It peeled right off easily, which surprised me.
※ "Release paper" is the term used in the instructions.
It doesn't look like paper, but don't worry about it.
Out of 32 holes, about 4 holes worth, so one-eighth of the entire circumference
had no tire tension. There are marks on the tire from riding in this condition,
but if they'd been attacking corners on a downhill,
I could have been killed, so it's good it didn't come loose.
↑The boundary
When I peeled off the tire, the tape for the rim holes mostly remained on the fundoshi side,
but the red ink from the Challenge marking on the fundoshi
also transferred to the rim-side tape.
And just this spot is shiny.
All Revolution 66 reverse Italian lacing. If you flip it over, it would become Italian lacing, but
looking at the direction of the hub and rim logos,
it's reasonable to think it was "laced as reverse Italian,"
but I suspect the real story is that it was "mistakenly laced as reverse Italian."
However, judging from the direction the quick release is inserted in the image at the top,
the customer was apparently using it in the reverse Italian configuration.
Hub relocation in progress...
Normally, there's absolutely no need to take such an intermediate form (just so you know).
It looks like the same topic as yesterday, but
yesterday's relocation was a coronal-plane relocation, and
today's is a sagittal-plane relocation.
Since wheels rotate, a coronal-plane relocation becomes the same as a transverse-plane relocation. The ground is written as "ぢめん" because it's ground (chi) + plane (men), but in modern Japanese orthography, this is considered incorrect. The same goes for "inazuma" instead of "inadzuma."
I was going to write about how when you do a coronal-plane relocation of only half a left-right tangent-laced wheel, if the anti-freehub side of the original 66 lacing and the anti-freehub side of the new 46 lacing are the same lacing pattern (same spoke and anti-spoke), then the freehub side of the original 6-spoke and new 4-spoke reverse direction, so at the boundary of the relocation plane, the 2 holes become continuous spoke or anti-spoke, making it impossible to split evenly. But I decided against it.
Knowing it doesn't help, and not knowing it doesn't hurt.
Besides, if I write it out properly, it touches on one of my meal-ticket secrets,
so I'd just be shooting myself in the foot.
Yesterday's wheel I made into Italian lacing, but
at the stage of the sagittal-plane relocation image,
the new rim (the small-diameter one) is actually JIS laced.
Built.
