Wheels Mfg outboard BBs... what's the deal?
Specifically these:
https://wheelsmfg.com/bottom-bracket...ano-black.html Shimano PF30s sit flush with the edge of the BB shell Like this: https://static.biketiresdirect.com/p...0/shmnb2-1.jpg So how do these work? Aren't the BBs to wide for the crank?

These are designed for 24mm Shimano cranksets, not BB30/PF30 cranksets.

Your first link is for PF30 frames, which have a 68mm wide shell.
Their BB meant for PF30 frames to be used with 68mm wide BB30 cranks does sit flush https://wheelsmfg.com/bottom-bracket...-bb-black.html As does their BB meant for BB86 frames with Shimano cranks https://wheelsmfg.com/bottom-bracket...nks-black.html |

they're an excellent way to have non-BB30-specific cranks on a BB/PF-30 frame. and to get a more stable bearing situation (though that's particular to BB30, not PF30) - no creaking, more easily swapped at home.

i have the PF30 to Shimano like the one you listed...installation and swap-outs are easy-peasy and so much smoother/quieter than any PF bearing. Plus you can switch out to a Shimano crank and get better shifting up front. If they're not flush to the BB face, you're doing it wrong.
