More wheels today (and so on).
Now moving on to the rear wheel.
↑I'll be swapping the hubs and rims on these.
Disassembled both rear wheels.
The original DT hub's spokes measured
292mm and 294mm,
and the original Chris King hub's spokes measured
269mm and 271mm.
I'm separating them into "straight" spokes and
"cross" spokes.
In my assessment, the Chris King hub's spoke lengths were proper,
and the DT spokes are about 1mm too long.
If I were to go back to the original combination—
DT 240 hub and SES 2.2 rim (A 2.2 rim)—
and build it as a 24H four-cross pattern, my calculations show
291mm and 292mm.
With rim brake rear wheels built identically left and right,
the difference is typically around 2mm,
but with rounding it can come out to 1mm difference.
As I noted with the front wheel, the original DT hub's tension was clearly loose,
and the same holds true for the rear wheel. The paint has chipped away
at the final cross contact point.
The way it chipped actually reveals it was built Italian-style,
which I find personally interesting.
The original Chris King hub shows no paint chipping.
There aren't zero signs of rubbing, but compared to the original DT hub,
you could practically say there are none.
↑This is the outside of the Chris King hub's freewheel-side flange—
aside from the spoke seating mark on the straight spokes,
the anodizing hasn't flaked off.
↑On the inner flange side,
there's a contact mark between the spoke and flange
just past the elbow of the cross spoke.

cross spoke (left in image) from the freewheel side
of the original Chris King hub.
Only the cross spoke shows
contact marks from the flange.
Some nipples have verdigris (a blue-green patina that forms
on brass and copper),
while others don't.
The SES 2.2 rim was originally set up tubeless, though at the time I received it
it was running tubed. There are signs of past tubeless use,
with dried sealant caked inside the bead hook.
Sealant has seeped into the rim interior as well,
and moisture from that appears to have caused the verdigris on the nipples.
Today I'm building the rear wheel with the Chris King hub
and SES 2.2 rim, and I'll reuse the verdigris nipples.
By the way, ENVE (エンヴェ) specifies that wheels must use
the included internal nipples to qualify for warranty coverage in case of damage.
Of course I could swap in brand new identical nipples,
but I've determined these can be reused.
Built it.
R45 hub, 24H, black semi-comp four-cross build.
I'll do the lacing later.
Based on my spoke length calculation,
the four-spoke set on the non-freewheel side of the new Chris King R45 hub came to 292mm,
so I'm reusing the freewheel-side spokes from the original DT hub.
Of course, straight spokes go through as straight spokes,
and cross spokes through as cross spokes.
The original Chris King hub spokes and original DT hub spokes
differed by 23mm on the freewheel and non-freewheel sides respectively.
If the difference had been around 15mm, I might have considered
shortening the DT hub spokes and making the new Chris King hub's non-freewheel side
a six-spoke build, but they're too different in length,
and the original DT hub spokes have a flattened square section applied
just past the thread end, making them impossible to cut anyway.
Since the flange diameter changed,
the final cross position is different too.
↑Freewheel side
↑Non-freewheel side
Spoke length is measured from the outer face of the nipple end,
flush with both the front and back.
↑This is the front wheel I built the other day—
because the tension is higher than before, the spoke threads
are protruding from the nipple.
I wanted to shorten the spokes by about 1mm, but
the spokes from the original DT hub have
that flattened square section applied,
so I couldn't cut them.
