We have a small hole at both end of the bar in wich a small rope is passed trough (one knot on each side of the rope makes it stay in there).
we slide the floater up and we can disasemble this small rope, slide it trough the hole (the rope has one knot on each end so you slide it on the other side) and retie your line on the other side of the hole.
that makes a bit more than 1.5 inch on each sides
The conenction to the know is a loop just like your kite attachment. After the adjustment you just slide your floater back down and you're ready.
Personally. i ride my two smaller kites (6 and 9) on one bar adjusted to the shortest and i have another bar for by 13.5M wich is adjusted to the longer setting.
Core recommand using the large setting for more than 9M and the short setting for less than 9M, with 9M you can choose whatever you like.
Honestly, even on smaller kite the longer setting works, it turns more for the same input force (
