Spinergy has wheels with similar spokes:

Once, I was fast. But I got over it.

Spinergy did this many years ago with their xaero wheels.

Spinergy didn’t exactly take over the world with Spox.

Wonder what the wind up is like during a wheel build.

IIRC, they're basically Vectran.

Should work fine...a tensile member is a tensile member. I wouldn't believe any "magical" claims about ride quality though.

The Achille's heel of them though is going to be their width. In other words, poor aerodynamics...especially as compared to bladed spokes. Not going to be "worth" any small weight loss.

Neither did topolino

UH, say what? Their site only shows tensile strength but what counts here is modulus and yield point. The peak force on the spoke needs to be well below the yield point, which will be way below the tensile strength.

I was talking in regards to them being part of a pre-tensioned structure...

In any case, I mis-remembered. It looks like the material is actually UHMWPE, also known as "Dyneema". That would mean they should have a modulus similar to Ti.

I think my concerns for this product would be:
1 - Reliabilty of the fiber/threaded end attachment
2 - Reduction in preload over time due to creep

IIRC the topolino wheels were absolutely terrible due to the thick spokes

Yeah, I pretty much never buy into any product’s compliance claims. If a wheel actually was compliant I’d be worried and wouldn’t want to ride it. FWIW it appears Spinergy makes bladed Spokes now... plus the wind doesn’t care what shape the spoke is under a disc cover :)

And temperature sensitivity as well - there will be some degree of stress relaxation simply from temperature changes (material will relax) in combination with thermal expansion (causing tension to drop further).

...and what if the "spoke" is PART of the disc "cover"? ;-)

Well we could also make a lead brick fly by putting a big enough engine on it. Question is, why would we want to?

There is a reason to try rigid composite spokes: aero.

That said these probably looked cooler than they performed. They certainly weighed a lot (I seem to remember them being 1kg or so heavier than the pair that replaced them on my TCR.
