What broke? Carbon or Alu? - Page 3

Cyclical stresses do cause the crack (unless it was already there), nucleation sites don't grow. All fatigue starts with a crack, if the nucleation sites never develop a crack you'll never have fatigue... just semantics there. You and I agree but you're afraid of calling BS when you read it.

I'm confronting the BS, not the authors of the BS, I've ignored dozens of personal attacks. Readers of this forum can decide if my (and your) explanations ring true or if they want to believe the bull****.

Example: I think the fatigue will have started long befor the crack appears - that's not the statement of someone who understands fatigue... don't you agree? Maybe he meant "long before the crack is visible", that might make sense, because the fatigue starts as a small crack (even microscopic) and then the crack propagates with a speed governed by the size of the stresses and the material's toughness. But if he knew that he wouldn't have phrased it the way he did. In Hincapie's case, the first crash almost definitely created a crack or a gouge that developed into a crack over the next series of cobbled sections. Chances are really good the same or worse would have happened to a carbon steerer in the same crash. I advise everyone who's in a crash where the handlebars or fork get smacked to do a good inspection of their bike before they ride Paris-Roubaix... no matter what components they have.

Another: Your argument is laughable and getting rediculous all the time - no presentation of an alternate explanation, no reason why anyone should believe his side over ours... just trolling. Folks can believe those of us who obviously have some education and experience in this area or they can believe the posters who write poorly spelled, unsubstantiated statements, and respond with puerile name calling.
