I received a Tōken (Japanese wheel manufacturer) C22A wheel from a customer.
It's a light-looking aluminum WO rim.
For some reason, I feel like I know the tension tolerance of this rim,
but I have no idea why.
All the spokes are CX-RAY, but on the freewheel side
they're tensioned so much that even if I were to build this rim on the tight side,
I probably wouldn't go nearly this far.
The impressive thing about this rim is that it can handle such tension.
About 95% of these rims fall within an actual weight range of 369–394g,
and around 70% seem to fall within 384g ±5g.
Though that's just my impression.
C22A...AL22...XR200... ugh... my head...
One spoke is broken, and the customer wants it repaired.
Since the wheel comes with spare spokes and nipples,
I'll use those to fix it.
The spokes have a slightly longer unbutted section compared to standard CX-RAY,
and the nipples are a special type that can be turned from the outer circumference.
But even if those weren't available,
I could repair it with standard Sapim CX-RAY spokes and 14mm aluminum nipples.
All fixed.
↑For some reason, the spokes aren't woven (crossed).
Black spokes make a squeaking noise when the crossing rubs,
but at this tension on the freewheel side, there shouldn't be any noise even if they were woven.
When not woven, the opposite-side spokes don't hold the same-side spokes inward toward the wheel hub,
so when shifting to a lower gear, spokes can more easily interfere with the rear derailleur.
This wheel uses tangent lacing on both sides, but
I think one reason why most complete rear wheels use radial lacing on the non-freewheel side
is because you absolutely avoid black spokes rubbing against each other and making noise.
