The threads are at a disadvantage in that they need to be machined schwinn crank bearings both sides and have a hard time sharing a centerline, whereas our OSBB vitamin sunlight machined from one side all at once — and round holes are easy to measure.
This is essentially the same as the BB30A and BB Ai Cannondale system described above, except that it uses bearing schwinn crank bearings rather than bearings pressed directly into the frame.
