Spacers for external bb or bb rings that can be screwed in more or less on both sides.
I may be over-thinking this, however (definitely am & wish I’d not gone down this rabbit hole...). My shopper biek has an odd bb shell width and is a bit of an arse to sort out. You’ll be fine with the Fuji - just ask a friendly bike shop to recommend the correct bb spindle length to line up your chainring and the SA sprocket.
