In the older GXP XR BB (that's a few letters, hey?) it actually has a spacer pressed into the bearing on the non-drive side. In the Team version it appears to be part of the bearing.

 

The problem I discovered the other day is that the overall spacing for the Team and the XR is different. so the crank arm couldn't tighten enough to "lock"  it on the spindle.

Yeah i found the 'spacer' to be part of the bearing on the nondrive side. Only thing i dont think this is a team BB tho.  Have you tried a SRAM BB? As this is exactly the same as supplied with the SRAM road groupset.
