    I have a bike with a race face PFBB30 adaptor which means I can run my 24mm spindle RF cranks – all good.

    The adaptor is one of these: http://www.raceface.com/components/bottom-brackets/bottom-brackets/bb30-x-type-adapter/

    The bearings have died and I need to replace them, I see no need to replace the entire adaptor unit, just the bearing race.

    Does any one have any experience of removing the bearings from the adaptor? Ideally I would like to keep the adaptor in the frame whilst carrying out the procedure.

    Many thanks


    Thought I would answer my own question, just incase anyone else has the same issue.

    The tool required is the Park BBT 90.3 one of these:

    This effortlessly removes the bearings without removing the adaptor from the frame.

    Bearings can ben be pressed back into the adaptor using a headset press and the bushings provided with the BBT 90.3. To get the bearing back the last part I used the old bearing as a drift.

    If you are still reading and interested the bearing size is 6805-2RS which I purchased for £4 each from our local bearing supplier.

    That’s it, preserved for the archives.


    thanks a timely post, I’m currently researching what bb to get for my bb-30 shelled frame and sram force giga-xpipe cranks and i’m probably going to get the wheelsMFG bb that screws together as the praxis works one is 8 weeks away from being in stock, it will be nice to be able to replace the bearings instead of a new bb so it’s good to know there are tools out there to do so.
    it’s a shame that there isn’t a screw together sleeve that takes external bb hollow tech/sram/fsa etc bb cups. there is the sram one that you loctite in (but no threads to guarantee parallel bearings) and an fsa sleeve you bash in, neither are ideal.
