As everyone has said, SRAM GXP BB. I have the Force 1 Cranks w/ GXP BB (Apex 1's before that) and everything works perfectly.
Also, I went from a 40 tooth to a 38 on my Roll. Can't say I noticed any real difference. You'll pedal slightly faster in the same gears. So keep that in mind if you like how it feels now.
