I have seen an unbelievable amount of nonsense in audio products. It's usually easy to find a way to discount claims.
It's also very important to understand how pervasive self-bias is. The car/tv/bourbon -you- buy is always the best, and you can feel it!
Kevin Cameron is a very highly respected cycle guy. This is what he has to say:

Right now, reports are rolling in describing big increases in top speed attributed to
5) replacing 52100 steel wheel ball bearings with miraculous new
ceramic bearings (photo above). Hmm, we know that the horsepower required to drive a vehicle through the air at speed increases as the
cube of the speed (speed x speed x speed). If we make a change and see top speed rise from 178 mph to 181, we can get a good idea of the extra power required by the ratio of cubes of those numbers. It comes out to 1.0514 in this case, so we can figure it took roughly five percnet more horsepower to boost top speed from 178 to 181 mph. If we're talking about a sportbike, engine power is probably in the range of 175, and five percent of that is nearly nine horsepower.
Each horsepower is 746 watts, which is the usual output of a red-hot kitchen toaster. Nine times 746 is roughly 6,700 watts of heating power. If our five nasty old-tech steel wheel bearings (two in the front wheel and three in the rear) were eating up 6,700 watts of power, or two toasters’ worth each, we should be able to see them nearly glowing after a speed run. Do they glow? For just $27 we can own an MS6530H Commercial Electric infrared remote thermometer, with which to make our own survey.
But wait. I’m all for personal freedom and self-expression. If you feel you must install ceramic bearings, get to it!
