What I'd like to do is transplant older Schwinn road bike 3 piece bottom bracket and crank set into a newer Schwinn mountain bike frame. When the fixed cup is tight the front sprocket rubs the chain stay slightly and chain is offset a tiny bit inboard. If I loosen the fixed cup maybe 1 turn, everything clears and lines up. I have a BB spacer, but it is too thick and I cant get the adjustable cup to take out the bearing slack then.
Can I put something on the fixed cup threads (like plumbing teflon tape) to keep the cup in place, at least so I can test ride the bike and see if I like the gearing? I also thought I could use JB Weld but would rather keep it removable so I can make changes to the bike.
