I suppose thats why virtually ALL aluminum, especially 7075 is anodized, to reduce it's fatigue life. Huh, better tell that to Mavic, Campagnolo, Chris King, and everyone else who anodizes there products since they are obviously ignorant to this. Guess thats why FSA, Specialties TA, and Race Face anodizes there chainrings, and Rock Shoxs, anodizing there forks, and virtually every rim manufacturer, not to mention the frame manufacturers that anodize there frames. It make perfect since now... they all do this so there parts fail more often and I have to shell out more money to them to replace them.
Obviously this is not true, anodizing and hard anodizing does nothing to the metal except add five ten thousandths to one thousandth of an inch of oxidation. Where did you hear that? Not to be rude, but thats one of the most stupid things I ever heard. How would you know, do you have first hand experiance? Apperently not.
Heres the only way anodizing could ever reduce fatigue life. If you were to heat treat aluminum, take it to the anodizer, and not tell them it was heat treated. If they didn't know the part was heat treated when anodizing it would appear that the part was being anodized way to slow. Because heat treated aluminum take longer to anodize, it would seem to the anodizer that there is an under voltage occuring. So, they would increase the voltage and as a result the metal COULD, I repeat COULD have a reduced fatigue life. But in order for this to happen the company would have to be totally ignorant to not tell the anodizer that the part was heat treated, the anodizer would have to be totally inexperianced or just a dumb ass not to realize the reason why the part is not taking the anodization and increase the voltage, which any knowledgeable anodizer would not do.
Besides, my inserts are not anodized to increse fatigue life, it's anodized to harden the surface and prevent wear. Surface hardness and fatigue life are two completly different and unrealeted things. Take carbon for example, super high fatigue life, but soft as butter. Next time when you try to talk crap try to be inteligent and KNOW what your talking about.
