It's the conventional wisdom around here, so I'm not gonna spend time googling for you. I don't know if Cannondale's CAAD 10 instructions say anything about loctite, but if you spend a few minutes searching around, you'll find a consensus that proper loctite usage leads to quiet BB30 bearings. You don't need a lot of it, and proper application won't hamper removing the bearings later.

(If you have cannondale cranks then this applies -
