Trying to remove my square tapered BB to fit on a isis one but the drive side wont budge at all. Used a massive wrench thing, which mangled the BB a bit but should still be enough on it to get it out. Also tried hammering in a kink in the side of it then hammering it with a flat head screw driver but no luck there either. left overnight coated in WD40 Anyone got any tips on what else i could do? Thanks, Carl
