Today it's wheels again (and so on).
The title says "also" built Nomu Lab Wheel #5
but that's not a mistake.
I received a rear wheel built with an AL22 rim from a customer.
It's the same as the XR200 rim, but since the Tni sticker remains,
it's definitely an AL22 rim.
It was supposedly built at some shop in Osaka, but...
Tni Wing 32H hub and Sapim Race spokes
built 2:1 with 16+8H.
The freewheel side is
all wobbly, and
the non-freewheel side is also
all wobbly.
The rim was shifted to the right side, but since less than half a year has passed since assembly,
it's not from age. It was like this from the start.
What a terrible hack job.
The reason they brought it in wasn't because it was loose and they wanted it fixed,
but because spokes broke two months after assembly,
and they wanted us to check it too.
But tightening this won't amount to much, and
since troubles that seem to stem from the 2:1 configuration have already occurred,
we decided to rebuild it completely.
So I disassembled the rear wheel, but
thinking about it now, there was no need to take it apart.
Because this rear wheel uses a 32H hub with a 2:1 build, but
the rim is 32H, not 24H.
In other words, this rear wheel is
a crap lazy wheel—basically a 32H radial rear wheel
with half the non-freewheel side spokes simply omitted.
The rim holes where the non-freewheel side radial spokes don't pass through
were filled with something like caulking compound.
Maybe they did this because calculating spoke length for the freewheel-side tangent build
with a 32H hub and 24H rim is a pain.
The current Fulcrum also uses the same
2:1 build with phase gaps, but
they design their rear wheels with rims that have more weight and height than the XR200,
so the radial runout directly below the phase gap stays to an acceptable level.
If you tighten this wheel properly with more tension,
you'd get radial runout that's honestly unwatchable.
If you really want to do a 2:1 build,
you should go with the XR300 24H rim instead.
The caulking compound came right off when I rubbed it with my finger—all 8 spots.
So I was going to do a 24H equal-number build on both sides,
and I switched the hub to an Evolite Hub 24H, but
since the rim was 32H, I couldn't build a wheel.
So, setting aside the fact that I disassembled that crap wheel,
I built the rear wheel for Nomu Lab Wheel #5.
Evolite Hub 24H, half-competition radial build with splice ties.
Next, the front wheel.
Wing Hub 20H, Race reverse-pull radial build.
The front wheel had no centering issues and was just slightly loose,
so it might've been okay with just tightening, but
the spoke length was a bit short, and it had brass nipples,
so I decided to rebuild it.
By the way, the short spoke length and brass nipples
were the same on the rear wheel too.
Built it. Using CX-RAY spokes and aluminum nipples.
Even though the hub and rim are the same,
before the rebuild it was 601g, after the rebuild it's 559g,
and since much of the weight savings come from the outer components,
I think it was worth doing.
Finally.
I rebuilt the rear wheel with the original 32H hub and 32H rim.
Half-competition 48-spoke radial build.
I'm not doing splice ties for now (we can add them later if needed).
First I want the customer to use it in this state
and see if it feels better than before the rebuild.
For this rear wheel, this is my compensation for my own mistake,
so I'm building it for free, spokes included.
