Wheels again today (and so on).
Now for the rear wheel.
↑I'm going to swap the hubs and rims from these two.
I disassembled both rear wheels.
The spokes from the original DT hub were
292mm and 294mm,
and the spokes from the original Chris King hub were
269mm and 271mm.
I'm separating them by inpoke "ヌ" and
outpoke "反".
In my assessment, the original Chris King
spoke length is ideal,
while the original DT spokes are roughly 1mm too long.
If I were to build back to the original combination—
DT 240 hub with SES 2.2 rim (A2.2 rim)
in a 24H four-cross pattern—my calculation gives
291mm and 292mm.
With rim-brake rear wheels laced symmetrically side-to-side,
the difference typically comes to about 2mm,
but after rounding it sometimes works out to 1mm.
I noted before that the original DT hub
had noticeably slack tension on the front wheel.
The same applies to the rear—the paint is worn through
at the final crossing contact point.
What's personally interesting is that the wear pattern
reveals it was Italian-laced.
The original Chris King shows
no paint wear.
There are some traces of rubbing, but
compared to the original DT it's negligible.
↑This is the outside of the freeside flange on the Chris King hub.
Apart from the bite marks from the inpoke heads,
the anodizing is intact.
↑On the inboard side flange,
there are marks where the spoke contacted the flange
just past the elbow of the outpoke.
↑Here are the inpoke (right side of image) and
outpoke (left side of image) from the freeside
of the original Chris King hub.
Only the outpoke shows
contact marks with the flange.
Some nipples have verdigris (the blue-green patina
that forms on brass or copper),
while others don't.
The SES 2.2 rim was originally set up tubeless
when it came to me, even though it was then run as a tube setup.
Dried sealant was crusted inside the bead hook,
and sealant had seeped into the rim interior as well.
The moisture from that seepage seems to have caused
the verdigris on the nipples.
Today I'm building the rear wheel with the Chris King hub
and the SES 2.2 rim, and I'm reusing those verdigris nipples.
By the way, ENVE makes it a warranty condition
that you use the nipples that come integrated with the rim—
at least if you want warranty coverage in case of damage.
Of course, you can replace them with new identical ones,
but I determined these can be reused.
Wheel's built.
R45 hub, 24H, black half-comp four-cross lace.
I'll do the spoke lacing later.
Since my calculation had the non-freeside four spokes
from the new Chris King R45 hub at 292mm,
I'm reusing the freeside spokes from the original DT hub.
Of course, inpokes go to inpokes
and outpokes go to outpokes.
The spokes from the original Chris King hub and
the original DT hub differed by 23mm
on the freeside and non-freeside respectively.
If the difference had been around 15mm,
I might have considered cutting down the DT spokes
and doing a six-spoke non-freeside on the new Chris King hub.
But the length difference was too great,
and besides, the original DT spokes have
a flattened square section just past the end of the threads—
they can't be shortened. So it was impossible anyway.
Since the flange diameter changed,
the final crossing position is different too.
↑Freeside
↑Non-freeside
The spoke length measurement goes from the outer end face
of the nipple rim-side and is flush front and back.
↑This is the front wheel I built the other day.
Because it's under higher tension than before,
the spoke threads are protruding from the nipple.
I wanted to trim the spoke length by about 1mm,
but the spokes from the original DT hub have
that flattened square section,
so I couldn't cut them.
