Fast and Smooth
You'll love them if you try them. Best upgrade for your wheels. I don't know if they really make you go faster, but the sound and feel of the bike definitely change.

Still breaking in but rolling like a charm.
Replaced all bearings on my carbon race bike with ceramic. Seems to roll pretty smooth.
