I just bought a new Leader track frame, and I'm trying to put in the BB, but neither side wants to go in. It wants to cross-thread. Everything is standard English threading and new (BC 1.37X24T, 68X111), and I am turning them the correct way. Neither side will reach a full turn before stopping, and I have tried about a thousand times. I haven't forced anything, and I'm only using my hands. It's a mediocre Sunrace BB, but I'm in Mexico, and it's the only one I could find that would give me the chainline I want. Furthermore, that shouldn't stop it from entering the frame. Any advice out there? Am I doing something wrong, or is there another measurement on the BB that could be causing me a problem. I have put in a number of BBs, and I have ruined one, so I know not to force anything. It's frustrating to experience this with all new merchandise.
