If unanodized Al was a significant corrosion hazard then we'd be seeing Campagnolo Record hubs and MA-2 rims failing left and right I'd think. And further, airliners which frequently have large unpainted/anodized Al areas would be dropping from the sky as well. It's my understanding that an aluminum oxide layer(same thing as anodizing in Al) quickly forms in any case on bare Al. I think the main reason for anodizing Al bike parts is primarily cosmetic- though I'm sure the people that ano their parts would agrue the point claiming significant advantages beyond mere aesthetics. I' m more than a bit skeptical nevertheless. Restoring anodized Al parts vs. their unanodized brethren is certainly a much harder excercise.
