Maybe I wasn't clear.
What I meant is that the cranks would spin freely with the old brgs, but with the new ones the crank would not spin as freely, and this I attributed to the new brgs which were stored for a long time before being used, and maybe the grease had stiffened.
However, after the first ride today the cranks spin already more freely.
I agree that cage and retainer are the same, but my point was when pressing on a brg race either inner or outer it should always be supported otherwise you risk damaging the brg.
