I just saw an add for a complete set of 5/32 ceramic balls for Campag
wheels. 60 balls for only $330......$5.50 per ball..YGBSM....

ceramic bearing balls do in fact cost a good deal more to produce than
steel ones. *and their precision, fwtw, it typically about 10 times
better. *how much is a single steel bearing ball?

grade 25, we sell for $.10 per ball..for bicycles, more than adequate.
So, ceramic is 55 times more expensive for 10 times rounder.

As a comparison, I just bought a "Mini-Pak" of 175 3/16" Grade 25
balls from Motion Industries for $5.35(US); which works out to $.03
per ball.
