I received a front wheel with a Mavic Record Mond rim from a customer.
It's a 32H radial lacing.
The other wheel (rear) that came with this one was garbage-tier before even considering the rim itself, so
I got frustrated and rebuilt it from scratch.
Just to be clear though, I'm not criticizing that wheel for
having lost spoke tension from sitting around for years
or having runout.
What I'm angry about is the shop handing over to a customer
a wheel with abnormally short spoke lengths,
a valve hole in the middle of a tangent spoke bundle,
low tension, and runout—all as-is.
The spokes are #15-based butted spokes, and
while there's no maker mark on the spoke head,
they're not Sapim either.
The hub is a Dura-Ace HB-7110-F, and
if I consider the right side of the image—where the hub barrel text reads correctly—
as the wheel's right side,
the rim label ends up upside-down.
There's a grease hole positioned opposite the SHIMANO stamp on the hub barrel, and
when I rebuilt the rear wheel, I aligned the phase
I saw looking through the valve hole at the hub barrel
with this hole,
but the original wheel wasn't particularly
assembled with that kind of phase alignment.
The spoke length is short, but
not catastrophically short,
so I'll retension it as-is.
By the way, the round-shaped cutting mark on the outer end face of the nipple
is a marker indicating
it's a #15 nipple.
There was centering deviation.
I interpret that as a sign that tightening is needed, so
I'm actually grateful for it.
There was also lateral runout.
The phase where the gauge touches the rim at just one spot
is shown in the image above, and this is where the largest radial runout is.
With the gauge in the same position, viewed from other phases
it looks like this.
There's not just outward runout
but also inward dips.
I corrected both the centering deviation and lateral runout
almost entirely by retightening.
↑ Center is now dead-on.
Both lateral and radial runout have been corrected.
The gap that appears to be there is
because the area beyond the serrations on the dropout has a taper shape.
Separate from inspecting the Record Mond,
the same customer also left me with a
Super Champion Record rim.
Super Champion is a French rim manufacturer, but
they have an English spelling and English pronunciation for their company name because
in the early days when bicycles were mass-produced as industrial products,
Britain was the leading nation in frame and parts manufacturing
and standards-setting.
Stronglight, the crank manufacturer, is similarly
French but uses English pronunciation for the same historical reason.
Regarding SRAM's DUB bottom bracket,
the manufacturer documentation specifies
how many mm and how many spacers to install on each side (left and right),
but there it refers to what's normally called the BSC thread standard
as BSA.
This is because Birmingham Small Arms (BSA)—a British gun maker—
had a period when they applied their barrel-machining technology
to bicycle frame manufacturing, and
that BSA established a standard: "1.37-inch diameter threads with
24 threads per inch pitch,
and the right-side threads shall be reverse-threaded,"
which was adopted as the British Standard Cycle (BSC)
industry standard.
I'm not sure why SRAM insists on the BSA terminology.
The hub is a Campagnolo
LFQR (Large Flange Quick Release) that I have on order.
It has a similar ring to SPQR (Senatus Populusque Romanus)
or LGBT (Low Gear Big Tooth) (→here),
but there's no connection.
So I tried to build the wheel, but
while both rims are 36H,
the front hub I received was 32H.
And the rear hub is...
40H.
The white stuff stuck in the flange holes is polishing compound.
They must have polished it before sending it to my shop.
So this time, I wasn't able to build wheels with the Super Champion Record rim.
