I have "upgraded" the headset expander plug and compression ring /base ring (the one with the holes to run cables through), so it matches the new version for the SL 7. However the new compression ring / base ring is a bit lower/thinner than the old one, meaning that the headset cover now sits so low that it is not clearing the frame. A solution could be to add a micro spacer or two (.25 mm each), to lift the headset cover back in to place, but I will need to cut them in a C-shape to make room for the cables. Another solution is of course to just use the one included with the frame. Anyone who has a need solution, or tried with the micro spacers?
