I would like to put a direct mount chain ring on my 2015 Fuel EX9 27.5. It has the X1 drivetrain with the 1400 crankset. Does this mean it is a GXP BB or is it BB30? I can't see any markings on it, and would like to know if I need a ring with a 6mm offset or not?

Thanks,

Looking at the SRAM installation instructions, GXP cranks have the non-drive side arm bolted to the spindle. 30mm cranks have the drive side bolted to the spindle.

Yes! Makes perfect sense, thanks. I didn't notice that when I looked at the install doc.
