Hey sorry it took so long for me to respond. The reason why I want to take the fixed cup off is because I would like to clean out the grime and grease it. Im overhauling the whole bike. Ive replaced the freewheel, cleaned and lubed the rear derailleur and cleaned the grime off my chainrings. I figured I would be thorough and do the same with the bottom bracket. Egh I know the tools are expensive but I know Im going to get some use out of them. I can service my bike myself and not have to depend on a local bike shop to do something as simple as cleaning out the grime and re lubing all the moving parts. Thats just my logic behind it. I'll say it again Ive tried using adjustable wrenches and I was unsuccessful. Honestly it may be my own fear of stripping the cups so I figured I should have the right tools and some good penetrating oil just for my own peace of mind. Dont want to damage my bike using the wrong tools.
