Don't get me wrong,I am not going to lube my bearings with it but for the superficial clean and demoisturizing after a rainy ride and general upkeep and cleaning it is great.
The big reason, I think, is that WD-40's "lubricant" seems to be a slight amount of mineral oil, which isn't a very good lubricant at all. I learned the hard way to never use WD-40 on my locks - it leaves some sort of residue on the inside that eventually gunks up.
I would implore you to give WD-40's new line of bicycle products a go, though. I'm a Boeshield guy, but I'm going to give it a go, see how it works out.
