Another day of wheel building (and so on).
Today I built up a carbon WO rim that a customer brought in.
I forgot to photograph the rim, so here's the finished wheel right away.
It's a carbon rim with an actual measured height of 88mm.
There are water droplets from truing the spokes, but don't mind them.
I built the free side with CX spokes and the non-free side with CX-RAY spokes.
For asymmetrical spoke lacing, this creates quite a dramatic difference, which I like.
This was the customer's request, but if I were building with this rim myself,
I might have chosen the same configuration.
If we set the specific gravity of 2.0mm plain spokes at 100,
the ratio between free side and non-free side comes out to 100.3:64.0.
Marvelous. Hehehehe. Oh no, I'm drooling...
The CX-RAY comes with aluminum nipples, but the CX uses brass nipples.
This time I've used aluminum nipples for the CX side as well.
A label is affixed on the opposite side of the valve hole.
According to it, the maximum spoke tension is 130 kgf.
That was helpful. When building a rim you've never worked with before, it's quite nerve-wracking
to build without knowing this specification.
And one more thing.
At the nipple holes on both sides opposite the valve hole position,
the nipples don't protrude as much as elsewhere.
Whether it's a rim seam or some manufacturing reason, I'm not sure.
Now, this is a WO rim, but
the customer is mounting a TUFO tubular clincher tire on it.
This tire is a special type with a tubular tire casing but with a WO rim bead,
and it can only be used on WO rims.
I'd like to say you get that tubular tire feel with a WO rim,
but TUFO tubular tires have quite a clincher-like ride feel,
so you probably won't get that.
You need to carry a spare tire of the same type as backup for flats,
but some models are quite light, and since you don't need rim tape,
this might be a good format for a dedicated WO race wheel.
Also, this rim's tire pressure limit is about 9 bar,
and this tire's specified pressure is 8-12 bar,
but since bead retention doesn't have much relationship to air pressure
（even if you pump it to 12 bar, it hardly translates to force pushing the rim's
bead section outward left and right）,
there's less continuous stress on the rim, so you might be able to use it at higher pressures.
