I own a set of Neuvation R28 SL3s. Unfortunately, I didn't get the Ceramic bearings so I can't be a lot of help on it.

John (Neuvation owner) used to have the info up on his site on the tools and steps you need to switch to the ceramic bearings as they are included loose. He changed the entire website design last month and it appears this information (including the tools section) got lost in the transition.

Either way if they don't come with proper instructions, just email him and he will help you out. He is very responsive to emails.
