I run one of these Ti BB’s. The problem is that it relies on friction fit to hold the outer shells of the bearings. Now all sealed bearing BB’s use friction to hold the bearing firm. But you can tighten down on the NDS cup to clamp down on that bearing. With these Chinese BB’s, both cups have flanges. These flanges tighten against the BB shell of the frame. In other words the cups are tightened against the frame and not the bearings. The bearings will eventually work itself loose.

Now if you could get one of these Chinese BB’s and substitute the NDS cup with a conventional flangeless cup, I imagine you’d be golden.
