SRAM Red Etap jockey wheels

paulbnix

I've had SRAM Red Etap on my bike for over 2 years and about 9000 miles. Most of the miles have been dry.

I dismantled the lower jockey wheel looking for the source of a drive train noise.

I think I have sorted out the noise and my question is about the bearings in the jockey wheels.

They look to be completely clean and smooth so I would prefer not to replace.

They are the original jockey wheels so I believe they are ceramic - not sure if that is full ceramic or hybrid.

Should I
- leave alone?
- wash?
- grease?
- oil?
these bearings and what with?

Thanks.

they are sram's hybrid ceramic

if they feel smooth fine, otherwise carefully remove the seals, flush out with solvent, regrease with waterproof grease, replace seals, sram recommend skf lghp2 grease
