Built a front wheel with EDGE45 rim and Bora hub

Another wheel day (and so on).

This is a continuation from the other day.
I'm rebuilding the front wheel with an EDGE 45 rim
that I'm taking care of for a customer (sort of).

Evo hub, 18H, CX-RAY, reverse-butted spoke radial laced.

The reason this rim is called just "45" rather than "1-45" (one forty-five)
is that it's the original model from before the newer version was called "1-45"
to distinguish it after "2-45" came out.
There was no heavier, more durable version of the 25 rim,
but with the 45 and 65 rims, the slightly heavier but more robust
2-45 and 2-65 versions came out later.
According to the manufacturer's explanation, they wanted riders to choose
based on usage rather than rider weight,
and they recommended the 2 version for cyclocross!
But from what I know, even after 2-45 came out,
1-45 continued to be used in cyclocross.
Part of it was probably that the 2 version wasn't very well known.

The serial number is in the 95,000 range—five digits.

The rear wheel had a Hyperion hub, but for the front wheel
I'm rebuilding it with a Bora 18H hub—not sure where they dug that up from.
This hub also originally had steel ball bearings,
and later had the retainer swapped for ceramic balls.
I considered the possibility that it had the HB-HY023 fitted,
which had an extremely short spare parts availability period as a rear hub,
but the bearings in both these hubs are almost certainly
the successor version HB-HY123.
So this is not "original Hyperion condition" but rather
"early USB condition."

After I built the rear wheel, the customer (sort of) contacted me asking
if converting it to CULT would have been better,

RIMG5185amx15.jpg
but I'm rebuilding the front wheel the same way—keeping it black!
If it were determined to be original Hyperion condition,
I'd have used the current steel ball/USB silver cone or the CULT cone.

Going back in the timeline a bit,
the internal nipple on today's front wheel was the first generation,
whereas the rear wheel from the other day had the second generation.

With the nylon lock-washer embedded on the outer perimeter,
at least they didn't get the orientation wrong.

On the inner side, though,

RIMG5181amx15.jpg
unlike the second generation, there's no relief dimension—
the threads basically start right away.
Since EDGE rims also have thin rim hole thickness on the inner side,
the spoke length range required by the first generation nipple is tight,
and even a length where the spoke threads are visible sticking out
from the rim can be acceptable.

It's built.

Like the rear wheel, I built it as a true rim.
Since it's 18H, I wavered between CX Sprint spokes,
but went with black CX-RAY.

RIMG5190amx15.jpg
I've marked the spoke to indicate "this is the right side" because

RIMG5187amx15.jpg
RIMG5186amx15.jpg
once the dust cap is installed,
the wheel has no left-right distinguishing characteristics.
Well, to be fair, the rim's serial number and model name marking
are positioned so they read correctly from the right side,
but this particular rim just happened to have those two oriented the same way,

RIMG5193amx15.jpg
whereas the rear wheel's rim markings are embedded in reverse relationship,
pretty haphazardly, so it's weak grounds for determining left and right.

For this front and rear 45 tubular rim pair,
based on the serial numbers and the age of the nipples that came with the rims,
of early, middle, and late (and ENVE),
the rear wheel corresponds to middle period and the front to early period.
Typical measured weights are around 278g for early, 294g for middle,
and 315g for late and ENVE.

But the actual weight of the rear wheel turned out to be late period
and the front wheel the same as middle period.
As for the specific weights, of course I'm not telling.
↑Man, this guy's got a bad attitude

Sorry for the wait! Please take a look at this image!

It's the rear rim!

RIMG5183amx15.jpg
It's the front rim!
↑Stop it!
