Hey - SRAM has their frame fitment standards posted and available online to the public. You can simply look and measure.
In general BB30/PF30 (same standard BTW just with cup or without) will clear the frame. Stupid to make a frame with a 30 BB shell if it won't. Same with the brakes. That's an OEM brake spec - believe it or not they do actually check this stuff when they spec it.
Quarq has replaceable arms/spindle standards now. Better than the 3 bolt ones from before.
Honestly the easiest is to get the GXP knowing that no matter what frame you move to you will be able to get a conversion to GXP as it is the longest and narrowest spindle option. You most likely won't go wrong with the BB30 version anyway. If you do then call Quarq. They will have you ship it to them and they will swap the spindle to the other standard. If it's new they most likely won't charge you. If they do it's only like $150 or so....about retail on a new praxis conversion BB with ceramic bearings.
