I hadn't read this before. I have a pair of Mavic CCU; they are a few years old and I actually was thinking how stiff they were (though I dont ride them much).Belisarius wrote: ↑Fri Mar 26, 2021 12:35 am
"I consider them advanced from the tech side.." They are not. Carbon was ditched by top makers (e.g. DT Swiss) due to fatigue life cycle. Lightweight had its own learning, and evident geometry lessons learned. Even then, their spokes have a finite life. Like all carbon seats, carbon shoes, everything that 'flexes' in the carbon world has a dual fatigue mode- the actual stress on the spokes, and the UV. For reasons that are obvious, the same logic does not apply to carbon seatposts and they thick and round self supporting shape. Take it to an extreme, in F1 carbon support slats fail very easily, sometimes suddenly, as a matter of frequency and vibration. But if you wish, ask Hambini- he will tell you not having the means to do a lifecycle test. Yes, even top brand carbon 'handlebars' fail randomly, hence my swearing by companies such as Deda- which use F1 grade resins and basic carbon material science, nothign too fancy, but they never break...
Winspace Iffy poor bearings (Hambini), and a solid materials, but, on spokes alone, short lifespan. You might not even notice how or when the wheel start flexing, but flexing it will. Those spokes will reach that one too many load cycles, and then start softening... Could be one, two or three seasons tops, or 15,000 kms - seems a recurrign figure for carbon fatigue in cycling materials (except frames). Anyhow, all this to say, nothign beats thos Sapim or DT Swiss cold pressed martensitic steel spokes....
But, take any Specialized S Works saddle, Fizzik or even Selle Italia carbon, squish them when done (and they bend) and asks yourself, if those fail, WHEN (not if) your winspace carbon spokes fail...
By fail we mean they will brake? Btw, what does UV refer to?
Thanks
