I got the carbon with black iridium pair pre-owned but reported as NIB and they are so far as I can tell in near perfect condition with one exception, or question at least. Where the right orbit articulates with the flex coupler there seems to be slightly more of a space between the orbit and the flex coupler and it moves more then the left orbit where it interfaces with the coupler. Is this standard. The hex bolts obviously have a tad bit of blue locktight on them so it appears as though they were not disassembled. I will post pictures in a few minutes if necessary but I wanted to know if it was typical to have one side of the flex coupler move more then the other. From having a circa 1996 or earlier original production pair of square wires the quality on this x-squared is tremendously better. I am pleasantly surprised.
