Has anybody out there replaced their steel sealed bearings with ceramic? I was looking to replace a pair of 28x12x8 bearings on an old wheel, and noticed that my choices were similar bearings for $12/pair, or ceramic at $72/pair.

I know that a lot of high-dollar wheels use them, but is there anybody out there who has upgraded an existing wheelset to ceramic? Did the turn smoother or easier? How long did they last?

Ceramic bearings make NO sense for bicycles. They are perfect for very high rpm (10,000-100,000), high heat, clean environments with nice radial loads. Not what you find on bicycle hubs and bottom brackets. Basically they're a waste of money that could be spent elsewhere.

They spin like crazy because they have shitty seals and a very low percentage fill of very thin grease. Not a recipe for a long life.

They are great for people who think how a wheel spins in the workstand has anything to do with resistance on the road with a riders weight on it.
Completely useless for anyone seeking actual improvement when riding.

Changing cartridge bearings is actually a clean, straightforward, and easy process. Very simple, takes less than 5' to do a wheel if you take your time. But that doesn't mean ceramics are the answer - you have to spend a ton just to get ceramics that aren't going to be worse than ABEC5 stainless bearings, and after you spend all that money you're left with no benefit.

Sounds like I just saved $56. I had a feeling that the only advantage was the "doosh factor".

They are a double rip off from the bike industry.

First, no benefit.
Second, ceramic bearings are not that expensive without the bicycle market sucker premium in the price.
So if you must, try to find your size with appropriate seals directly from a bearing supplier.

Yeah, I still remember the $10 titanium water bottle mount bolts.....
