Can I replace ceramic bearings with steel bearings? Bought a second hand bike that needs the hubs serviced. The hubs are Campagnolo Shamal Ultra which have Ceramic bearings.

I'm yet to tear them down and take a look at the insides but heres a pic from outside.



I know it's a downgrade but I don't really want to pay the price of the bike again on new bearings, I've only ever seen questions and threads about people upgrading .. can I replace ceramic bearings with steel ones?

For clarity, I will be looking inside the hubs to check what actually needs replacing before making purchasing decisions, however, I want to know if it is technically possible to replace ceramic for steel and or if there might be any issues with the races used for ceramics accepting steel, are they different materials etc.. 

I found the technical manual here
You haven't checked inside the hub but are planning on a possible downgrade?  Best to open it and check first.

I don't personally own anything ceramic, but one of their main advantages is durability.  I've seen estimaguesses of 50k-100k km life for "quality" ceramics.  Its unlikely Campagnolo used knockoff bearings from new.

Answer: Yes, but check inside hub first.  No point fixing a non-problem.
