I bought a used Truvativ FireX 3.3 GXP bottom bracket/crankset, to be installed on my Giant NRS frame with a 68mm bottom shell. The bottom bracket comes with two spacers and online documentation suggests that I need both spacers.
The problem is, one spacer is thicker than the other. Which spacer goes to the drive side and which spacer goes to the other? The manual does not specify.
