Hey guys,

This is probably not even worth asking about, but I just to be sure. (I've looked around with the part number, and all I've found are places that stock it rather than installation instructions). I have this bottom bracket to install:



I see that indented ring on the main enclosure, and I wonder whether it should indicate something to me. Can anyone confirm whether it should go to the drive side, non-drive side, or doesn't matter? Should the side of the enclosure with the indented ring go in the cup that also has a slight indented ring on its inside (left in the photo)?

Thanks!
