Info from Naish:
It has come to our attention that some of the X2 control bars were
assembled incorrectly at the factory. Specifically, the knots on the center
strap extension lines are not tied in the correct position on all the bars.
Because of this and after hearing several of your questions relating to how
the strap should be set up, I have prepared the attached PDF file which will
hopefully be helpful to you. We apologize for the discrepancy in the lengths
of the flying lines and regret any inconvenience this may cause. The
factory has since been producing the straps correctly, and this will not be
a problem in the future. Please refer to the PDF file for an illustration.
Keep in mind that the stopper on the right line shortens the length of
that line, whereas the left line does not have a stopper on it.
