Is it a KCNC and/or BB92? I had a nightmare getting my KCNC BB92 out.
I resorted to using a chisel to mash the inner sleeve to pieces and then get some purchase on the cups.
It aint pretty and you have to be careful you don't goudge your frame, but as the sleeve is quite soft (either plasic or very thin metal depending on what bb) then its easy to deform without goudging your frame and then get something to purchase on with a drift.
I suppose a vagely more controlled solution might be to use a dremel or a drill, again to attack the central sleeve?
