Hi. I've been told that full ceramic jockey wheel bearings should be left dry but it just seems "wrong" to me- what do you guys think?
Thanks

If they are actually all ceramic, they need no lubricant. The overwhelming majority of stuff sold to cyclists are not all ceramic, though--they are steel races with ceramic balls. Short answer: because they run with little-to-no heat, and have a low friction coefficient between the balls/races (those two points are related), they don't require lubricant.

They should still be periodically cleaned, though.

Nice one, thank you

I still run a light grease like Slick Honey in mine.

And because of this, the money spent on ceramic jockey wheels seems completely pointless. The increase in performance is equal to waxing your toe hair before you ride....

What's wrong with waxing your toe hairs?
It makes everyone go faster.

I was hoping I wasn't the only one.
