hmmm....you pulled up my old thread.

I'll give an update.

I did have hybrid ceramic bearings installed on the new American Classic 420 wheels. the mechanic let me play with the different bearing assemblies in my hands. including some all ceramic bearings. He removed the interior dust covers on the hybrids and installed them on my wheels. In my hands they seemed to feel like they rolled better. It seemed like the wheels spun better in my hands after the ceramics were installed.

The total cost was $150. I never used the wheels prior to the change so I can't give a comparison for ride, but I'm very pleased with what I've got. It was worth the cost to me to try it.
