Bottom bracket swap

My road bike is currently fitted with an Truvavita Elite ISIS crank. I have a SRAM Red GXP crank I would like to switch with it. Is the frame threading compatible between the ISIS BB and the GXP BB assuming they are both English threaded?

English threading is English threading and any bottom bracket with that threading will work. I assume your current bb width is 68 mm or standard road width. Some MTB's use a 73 mm bb shell with English threading and these aren't usable with road botttom brackets and cranks.

So the diameters should be compatible between bb styles?
