I would never use ceramic bearings either, the amount of gain you get is so small they say it can't be measured, therefore it must be physiological, Now before you start yelling at me you need to read this, and read the whole thing, no just scan it:

There are a lot of things on the market for bicycles that promise the moon but fail to deliver. The TDF race is proof of that, the average speeds since 1955 have only gone up by 3 mph! your talking about old steel bikes running with 10 speed setups, no aero nothing, bikes that weighed 21 pounds, poor tire designs, 60 years later (in 2015 on the chart) we have aero dynamic everything, lighter bikes, ceramic bearings, twice as many gears, 14 pound bikes, modern training and special diets, pills, powders etc and all we can muster up is another 3 mph? Wait, I'm not done, the race use to be 700 miles longer back in those earlier days than it is today! So if you really think about it, the only reason speeds have gone up is because the racer rides 700 miles less!!
Now look at that chart, the spike you see at around 2005 was the doping that was going on real heavily so doping does work! In 1955 the race was 2,793 miles long, in 2015 the race was 2,088.
I have a some theories about all of this, but either the modern ways of training are not as good as the older ways were, but people think the modern way is better because, well, it's modern, it has to be better; OR, the human genetics/DNA is getting weaker; OR, the modern bikes really are not that great as marketing leads you to believe. It could be a little of all of those things combined.
So I really think spending money on ceramic bearings is just a pie in sky thing, but it's your money, spend it as you like.
I was in the corporate world for about 25 years starting in the early 80's, the big thing back then was golf, I remember all the mumbo jumbo scientific jargon they use to splatter all over some wiz bang golf club, and if you buy those clubs your golf game will soar. I had a fellow office guy that went out and bought a brand new set of clubs, these bad boys cost $2,000 a PIECE! he was an avid golfer, and decent one at that, but he wanted to make sure he could beat others on the course, so he bought those clubs because of all the marketing, it had to be true right? So after his first game with the clubs he came back into the office the next day and I asked him, "how well did those fancy and expensive clubs work out?", he told me to shut up!! LOL!!! His game never improved over the time I worked there, his game was like it was before he spent all that money. Initially he was angry about buying the clubs but as time went on he accepted his mistake and just played them.
I think we get caught up in all the mumbo jumbo scientific jargon in cycling now, we read this stuff and it seems to make sense, after all someone more intellectual than us designed it and worded it so it must be good stuff, but it's not, it's just meaningless words to impress us, and more times than not it works to sell a product.
