so i just got the 390 bindings, while i was seting the highback roataion up to 4 degrees i noticed that the highback wouldent go all the up, like the peice on the back of the highback was not touching the back binding bar. It touched when the roation was on 0 degrees.. idk if anyone gets it but if u got the 390 and you rotated the highback does it sit on that metal bar. help=[
the instructions can be a bit confusing for highback rotation at first on the 390s. I have noticed that when in the Zero degree position they tend to fit into the metal portion of the binding perfectly but as they are rotated the curve is obviously slightly different and the plastic tends to scrape against the heel loop on one side. the plastic is flexible and will conform to the new shape after a short time.... no worries.
