[QUOTE=DMF]You got that reversed. The one assembled correctly (and apparently by Shimano) is the one with the spacers. Besides, the way the cogs are offset, it looks as if flipping the inner ring increases teh spacing.
Both show chain scarring on the inside of the big ring, though. Is that abnormal?

You're right, I missread your post. I don't remember ever seeing spacer washers on Ultegra 9-speed cranks, my wife has had 2 9-speed Ultegras.
Don't know about scarring.
