Another wheel day (and so on).
Continuing from yesterday.
Built the front wheel for my partner.
PowerTap hub, 20H
CX-RAY spokes, reverse radial lacing.
Even though it's a PowerTap hub,
the power measurement function is
naturally only on the rear hub.
This front hub was created by the manufacturer
to sell complete wheelsets for both front and rear.
The customer who brought in the rim this time
is technically a customer,
but they belong to the same team as me, so
I can be a bit more candid.
Looking back on it,
I built a CXP Pro Carbon 40 UST rim for a different job just the other day,
and that one is heavier in absolute weight,
but I think it has superior height-to-weight ratio.
As an example, the rims on Nomu Lab Wheel No. 1 and No. 5
have rim heights of 30mm and 22mm respectively,
and weight (average of many actual measurements, not spec sheet numbers)
of 462g and 378g,
so that's "84g difference for an 8mm height difference."
This comes out to roughly "about 10g per 1mm of height!"
as an evaluation.
In contrast, between the Open Pro Carbon 25 UST and
the CXP Pro Carbon 40 UST,
there's a 15mm rim height difference (the difference in the model numbers,
strictly speaking not the same as actual measured rim height),
yet only about 15g difference in weight.
Compared to the earlier example of "about 10g per 1mm,"
this becomes "only about 1g heavier per 1mm of height difference,
so with higher rim height, the weight is distributed thinner toward the inner structure,
and shorter spokes mean a stiffer wheel,
so basically it's all good news, isn't it?"
I'm not going to tell you the specific weights.
If you want to know, go ahead and calculate it yourself from the CXP 40.
↑Man, that's harsh
Sorry for the wait! Please take a look at this photo!
It's the Open Pro Carbon 25 UST!
I've also included the CXP Pro Carbon 40 UST
from the other day!
↑Stop it already!
