Its a giant safety issue on the road. Good grief, they almost banned hookless in the peloton over this. New rules require strict ETTRO compliance regarding tire size/internal width. So I don't know if was the poster or the rim, but that needs attention.

Definately a big safety risk.
I think I heard from some CRW wheels users also have this issue.

Are carbon spokes worth it? I'm worried they ride harsh and are more difficult to tension due to less stretching nature of the material. Looks and weight are great - price also justifiable. But are they actually better as for ride quality, serviceability and longevity?

I will buy only carbon spoke wheels from now on. Have now already several carbon spoke wheels and the differance is noticable. Much better acceleration, stiffness,... And I find them just as comfortable as steel spokes. And if one worries about that, just drop a few psi in you tyres. The rolling resistance differance will be practicly zero, but you add comfort.

Service? Still not needed. And 2 sets have +10k km, and one set a bit bellow 10k km. I have about 80kg and do lots of steep climbing with lots of out of the saddle outbursts.
