Just found this on Koegel

"Both standards are based on the standard BB30 or PF30, but with 5mm added, only on one side. Hence the ‘A’ stands for Asymmetric. The official word is that it helps build frames with better chain lines, the result is that it only fits a PF30A specific crank set. That’s right. Any Shimano, Sram, FSA, Campagnolo or Rotor will not fit unless you load up a bunch of spacers."

This is where my confusion comes in - how would spacers help in this situation (wider BB than your spindle) wouldn't you need like...negative spacers?
