Don't ceramic bearing balls just crack in half or seize up as soon as grit gets in there? Hardness is not a good thing, which is why they're not recommended for MTBs. In the real world, for those of us who actually ride hard and aren't supported by personal mechanics, pivots bearings don't need to roll well, they just need to stay lubed and not freeze up. Maybe this conventional wisdom about ceramic is wrong, I'd like to hear from people who test (and by that I mean abuse) their stuff in our winters and go 6-12 months between bearing service.
Only one thing matters in pivot bearings: resisting gritty, nasty, wet contamination. If this new technology can do that better, then sign me up.
