tomPietrowskiDepends whrre they were set when mounted but the marker royals along with the sth tend to have the most adjustment. But don't discount a remount. If you change one size in boot you can often move say just the heels and still have the heel in the middle of the track where it should be.
soupcanIt's a matter of 9mm smaller. Realistically it should be fine eh? I'm going into a tight performance boot and ideally I don't really want to put another set of holes in my ski.
tomPietrowskiIt's quite a bit but see. Really though you don't want to run them at the extremes of the track so simply adding 4 more holes may be a better option (you won't be able to remount toe and heel) but have a tech look at it and see wha the thinks.
It's probably too small a change to remount because the holes will end up too close to the originals.
tomPietrowskiYou can get around that by just moving the heel or toe. By only moving one you can move the holes far enough so that they won't interfere
rozboonGenerally, but if the total move you require is 9mm then you are left with a total of 5.5mm of core material between the edges of the holes, which I personally wouldn't be comfortable with. I suppose you could move it a lot more than 9mm then screw the binding way back along the rail, but the entire discussion is purely academic if OP can safely move the heel on his skis 9mm forward.
Again, personal preference only, but I'd rather have the forward pressure a click or 2 away from perfect than remount. But that's just me.
