So, 68mm bb shell width, English BSA thread, dub bb and crankset with Quarq PM, so 28mm diameter spindle diameter?
Installed the full crankset (ds + NDS), with the 3mm spacer on the drive side. The front derailleur is struggling to move the chain up from the smaller chainring to the big one. I'm not sure if I should re-adjust the front derailleur, or remove the 3mm spacer.
For reference, the old GXP bottom bracket didn't have any spacers installed...

My bad, I meant BB shell width side to side (from nds to ds), and spindle length (not width). The reason I ask is that GXP come in 68mm and 73mm. See pic below to find yours.
You’ve installed the crankset to full torque: does it spin freely and without play? If yes and you’re confident at adjusting the front derailleur, then try adjusting the derailleur.
Edit- cloudy minded right now but from what you’ve written it sounds like it should be properly installed with that 3mm spacer, which is the minimum for that BB.

Replying again in case you’re waiting for a notification. When you say the crankset is several mm outboard, is that with the nds crank installed or are you not able to install it? Or is it that the front derailleur shift far enough to cover the crankset?
