I have a project one build that has a ceramic speed BB. I just regreased the bearings and reinstalled the SRAM GXP crankarms. With light torque the cranks spin fantastic! However, when I torque the cranks to SRAM spec, 48 Nm, they barely spin. No wave washer is installed. Just the dust caps. This is beyond frustrating. What am I doing wrong?

I tried to upload a video but apparently I do not know how to do that.
