Sapim CX Ray vs Alpina Hyperlite Aero

[Sebastian]

Regards the data sheets it's more than noise. 
And cold forging raises the stiffness due to grain boundary movements and gliding of layers..Basically a big "crash" crystallographically.. like traffic jam... nothing (atoms and layers)  can move that easy, cause everything is stuck. Well that's frankly a little bit too simple, but that's what happens.

While that is totally true, Sapim will 100% apply some form of heat treatment which will reverse some of the martensitic cristalline structure in the metal after cold forging. After that amount of forging, this spoke would be way too brittle otherwise. After all, the CX Ray is known for its exceptional fatigue resistance. I’ve never seen one break.
Since we know neither the exact alloy they’re made of nor the exact heat treatment process, it’s impossible to know how similar the Laser and the CX Ray really are in their metallic structure.

And apart from all that, they definitely feel different IME

A friend crashed on a wheel using Pillar wing 20 spokes. He crashed fairly hard, and broke 4 spokes, from memory, front wheel. Do you think the wheel would have survived had it used Sapim CX Ray? Hubs and rim were fine, he had it rebuilt.
Fatigue and impact are different things, but it's worth asking
