Did a ceramic bearing crank the other day.  The bearings are 30grams/44grams lighter per bearing on the H2 and man does it spin SMOOOOOOTH!!

What about the bearing with snap ring groove?
Are you able to get that one with ceramics and plastic cage too?

Yes, all of the main bearings for all of the triples are available in ceramic with plastic cages. All of them are also rebuildable.

There is also the option of plastic cages and steel balls instead of ceramic. A bit less friction from standard steel cages but nothing compared to ceramic. The biggest pitfall with ceramic is $$$$$$ :shock:

FYI I am no longer using the RB Tech bearings as I have had to return too many that were not within my specs. No failures to date, but better safe than sorry. Japanese Koyo bearings only :D They are now included in the rebuild cost.
