I am restoring my Peugeot P8 E and currently I am replacing the bottom bracket with the loose-ball French bottom bracket cup set from Harris Cyclery. The problem I am having is that I cannot get the fixed cup removed. I have tried the bolt and washer trick that Sheldon Brown talks about on his website and I have tried a wrench, but even after using penetrating oil it will not budge. I was hoping maybe somewhere on here knows a better way to remove it. Thanks.
