Another day of wheel building (and so on).
A customer dropped off a Novatech D411/D412 hub with me.
It's a straight spoke flange disc brake hub
with a 6-hole rotor mount.
It has 7H/14-spoke flange holes on each side,
but calculating spoke length is a pain...
Huh? I've seen this before! (→here)
So even though the brand and hole count are different,
I've built this hub before, so calculating spoke length was straightforward.
Actually, I didn't make any mistakes.
But... (more on that later).
By the way, about that prime brand I linked to earlier,
an IT technician acquaintance of mine
wrote about prime carbon rims on his blog,
and got absolutely bombarded with protests
from a certain unnamed wheel brand saying
"Stop interfering with our business!"
Since this IT technician istechnically not an industry professional but an amateur,
they shouldn't have gotten angry about it.
Actually, getting needlessly angry over something like that
is basicallyadmitting (knowing full well)
where their rims really come from.
All built up.
The rim is an Iron Cross 28H.
Due to the flange hole configuration, I can't avoid 3-cross on both sides, but
On the non-rotor side, I used Sapim Race spokes,
and on the rotor side, I used Sapim Leader spokes
to create a mixed-diameter build on both sides. This corresponds to spoke weight ratios of 85% and 100%,
which is equivalent to DT Competition and DT Champion respectively.
I didn't lace the final cross on either side.
On the prime hub wheels I mentioned in that link, both front and rear wheels
use all CX-RAY spokes for lightness,
but whether to use mixed-diameter lacing with
the amount of dish (dishing) you get with a disc front hub
is a very difficult question.
In past examples, I've built almost all Iron Cross 28H rims
with all CX-RAY, and that's because
with straight-gauge spokes I can incorporate mixed-diameter lacing on both sides
and lace the non-rotor side, which also
relates to spoke selection.
I mentioned earlier being amazed that Zonda DB rear wheels have reverse mixed-diameter lacing with G3 lacing,
but I was also impressed that the front wheels have G3 lacing.
As I'll write in the next article,
mixed-diameter lacing and mixed-count lacing both create
left-right spoke quantity differences in the same way.
On the Zonda DB the front hub also has ultra-asymmetric flanges,
so considering that, this hub with small/small flanges
seemed to me like the right amount for this level of mixed-diameter lacing.
As a result, heh heh, I pulled it off—
if you close your eyes and grip the spokes on both sides,
you can't tell it's a dished hub (can't distinguish left from right)
—the deformation amounts ended up that close.
It wasn't completely calculated from the start, but it worked out.
Got the rear wheel built too.
Same as the front wheel,
on the side where the spokes stand up (freewheel side) I used Leader,
and on the side where they lay down (non-freewheel side) I used Race,
but unlike the front hub, having a high-low flange arrangement seems to have a real effect—
the non-freewheel side is suspiciously loose.
The dish from the freewheel body really is half-crazy massive.
There's also the option of using Leader/CX-RAY with maximum mixed-diameter lacing,
but the customer specifically wanted silver round spokes,
so I couldn't go any further.
I didn't lace the final cross on the freewheel side, but
I did lace it on the non-freewheel side.
Silver spokes don't make noise from flexing friction, and
I laced it that way in case we want to add spoke-tape (bracing wire) later, though we didn't this time.
By the way, among Sapim's straight spokes,
the 14-gauge plain Leader and the lightweight aero CX-RAY
are available in plenty of lengths in both silver and black.
↑For Leader, since the 310mm version has no threads,
anything shorter than that is fair game.
But the domestic distributor's stock of Race straight spokes
is limited to silver only and in a limited range of lengths, so
even using the longest length uncut, it comes up about 1mm short—
I built it knowing this.
The front wheel's right side and rear wheel's left side are nearly the same length
(they differ by about 0.3mm in theory),
and the image above is from the rear wheel's left side.
If that won't work, the only option would be half-Leader or all-Leader spokes,
so I had no choice.
