Why don't the pictures in loimpact's link and in your post match. He shows inboard bearings while you are showing outboard bearings. I can't see what the bearing diameters are, but they are most likely 24 mm. The adapter is probably for Shimano cranks in a PF30 shell. But if the diameter is 30 mm, that would be an adapter for an FSA BB386 EVO crank in a PF30 shell. Must be the former, because I have never been able to find latter.
