Okay, let me get this out to be sure. It's faux GXP, more like direct mount intended for BSA?
So I just get the cranks & direct mount chainring or the adaptor if I want 104bcd chainring. Use my existing Shimano bb shells and just add/minus spacers for 68mm or 73mm.
Btw, was it correct for me to equate GXP with direct mount?
