A customer brought in a Token C22A wheel for service.
A light aluminum WO rim.
For some reason, I feel like I know the tension tolerance for this rim,
but I can't explain why.
All the spokes are CX-RAY, but the freewheel side
was tensioned so high that even if I were to build it tight on this rim,
I'd probably never tension it that much.
What's impressive about this rim is that it can handle that kind of tension.
It feels like about 95% of these rims fall within a measured weight range of 369–394g,
and roughly 70% seem to cluster in the 384g ±5g range.
Though I'm just guessing here.
C22A... AL22... XR200... ugh... my head...
A spoke is broken, so the customer wants it repaired.
Since spare spokes and nipples come with the wheel,
I'll use those to fix it.
The spokes have a slightly longer non-butted section compared to standard CX-RAY,
and the nipples are a special type that can be adjusted from the outer edge.
But even if these weren't available,
repair would still be possible with standard Sapim CX-RAY spokes and 14mm aluminum nipples.
Done.
↑For some reason, the spokes aren't crossed.
Black spokes squeak and squeal when the crossings rub,
but at this tension on the freewheel side, even a laced pattern should make no noise.
When not laced, the outpoke doesn't push the inpoke inward toward the wheel interior,
so when shifting to a lower gear, the spokes are more prone to interfere with the rear derailleur.
This wheel has tangent lacing on both sides,
but I suspect one reason pre-built rear wheels often use radial lacing on the non-freewheel side
is precisely because black spokes rubbing against each other
will absolutely never create noise that way.
