Rebuilt the rear wheel laced with Tni ROAD50 rim

Another wheel day (and so on).

Continuing from yesterday.
I'm rebuilding the rear wheel laced with the same rim as the front,
but this one is more the real deal.

Evo hub, 24H, all-race 4-cross lacing.
Whether it was loose to begin with or has sagged over the years,
it's on the loose side from the freewheel side,
while the non-freewheel side with radial lacing is right at the edge of what works
as a wheel in terms of low tension.

The rim on the front wheel showed manufacturing/shipment dates
of 2011 based on the sticker,
but this rim was 2009 for both.

The reason I was concerned about the front wheel spoke length was
because I wanted to reuse the spokes from the rear wheel's freewheel side.
I wouldn't claim my calculation of spoke length is "absolutely correct,"
but if they're too short, I can't reuse them.
I wanted to know from the front wheel whether this builder's thinking about spoke length
was close to mine.
As it turned out, the front wheel spoke length was
exactly the same as my calculation (within 1mm),
and the rear wheel freewheel-side spoke length was
about 1mm longer than my calculation.
This seems less about spoke length philosophy and more about
a difference in how they interpreted the internal nipple correction value.
Rather than cutting 1mm off the freewheel-side spokes,
I'll just reuse them as-is.

I'm replacing only the non-freewheel side with CX-RAY,
and like the front wheel, I'm doing a complete disassembly because
I'm not happy with the nipples being used.

I removed just one spoke to check its length,
but since I wanted to maintain the original pattern of inpokes and outpokes,
I'm cleaning it with the spokes still threaded through
the freewheel-side flange.
The freewheel body on the hub
originally would have had a three-pawl Shimano 10S unit,
but it's been changed to a four-pawl Shimano 11S version.
