A SRAM GXP 24/22 mm crank fits a BSA shell with a GXP-specific threaded BB. The drive side is 24 mm but the non-drive bearing is 22 mm, so the BB must be GXP, not a plain 24 mm Shimano unit.
A GXP crank bottoms out against the drive-side bearing inner race, so there are no spacers to fiddle with, but it must be a GXP BB or the non-drive side will have play.
