I’ve got a press fit bb92 in my new frame ( Privee Shan) thought it was going to be a complete nightmare at first as the bearings didn’t want to go in AT ALL deforming badly, but turns out u was sold some road ones by LBS by mistake. Proper ones ordered, and went in nearly all the way with a firm shove. Very tight at first, cranks wouldn’t even spin one complete revolution, but have freed up a bit. Survived a very mucky and gritty ride a couple of weeks ago with no complaint.
I’m not particularly hard on kit, I expect these will last 18-24 months before replacing them, no worse or better than external BB cups or any other cartridge bearing system. I see hope are making them now, and I’ve had good longevity from their stuff before I may get one of those
