a roof-rack casualty run over and discarded at the side of the road has
yielded the above interesting rim sections.

Great pictures. Presumably the point of the "integrated nipple" is so
they don't have to make holes in the inner-wall?

Still, not much fun if you ring the soft aluminium threads off one of
them by overtightening the spoke.

presumably.

how would you do that? unless you're an unschooled amateur that's not
using a tensiometer. inability to follow instruction is hardly a design
flaw.

That's me.

Check.

Yup, I have that inability.

I didn't say it was.

Actually IIRC these wheels have aluminium spokes too so it's not clear
whether the rim threads would strip before the ones on the end of the
spoke.

spokes are not threaded.

"One wall of the rim is drilled with a tapered point with carbide that
heats the alloy, and pushes it inside the rim. It creates a chimney
that can then be threaded. The integrated M7 nipple can be screwed
directly into this thread.

_The rim is stiffer, which provides a better power transmission
_The rim has better fatigue resistance (4 times stronger)
_On MTB wheels, this makes the rim airtight for UST tubeless
compatibility "

I see. I was just starting to wonder how they screwed in to those
threaded sections in the rim-- I thought perhaps the whole spoke rotated
(and was straight-pull). But that would be no good since they are aero
spokes.
