Jockey wheels that fit 688-rs bearings?

[Sakizashi]

Does anyone know of any alloy or ti jockey wheels that take 688 bearings? I am not looking for a full OSPW. Looking to play with swapping bearings. Thanks!

How big do you want to go? AliExpress stores sell jockey wheels with steel bearings in alloy and POM material. Just do a search for jockey wheel steel bearing.

I would prefer 12t.

I want to be able to press in a few different bearings and see how they stand up to use / pressure washing etc, and 688 is a nice common size with options from the very expensive (e.g., enduro xd-15) down to the very cheap. So far, I have learned that ZTTO seems to use the 689 size.

I messaged a few aliexpress sellers i found using the the search terms you suggested. Thanks!
