FKS Forward Pressure

Hi all,

I'm having some problems getting my new bindings set up perfectly. Went dry skiing last night and had a pretty major stack trying to five a medium sized kicker. Normally with I would have expected both skis to come off but they stayed on and I tomahawked a bit. In fact I didn't release all session. I know FKS have good retention but this seemed a bit odd to me.

My DINS are at 7.5 and 8, Im almost 13 stone and Im a pretty aggressive and advanced skier but relatively new to park.

Ive done a bit more research about the correct forward pressure on FKS today and it seems to me that my bindings might have been drilled a little close together and the shop set the pressure far to high as the white tab was pushed well backwards with my boot clicked in.

I have fiddled around with the forward pressure arms and unscrewed them to their maximum extension but the white tab is still pushed a couple a couple of mm further out than the plastic indicator tabs. Is this a problem and does it mean that my bindings won't release when they should?

I'll try and put up a pick of the position of the white tab and the forward pressure arms later.

well in all bindings forward pressure is key esbecially the fks...you might need to get your bidings remounted and have the shop set the foward pressure correctly, bc a knee injury wud SUCK1

Here are a few pics Ive taken to show the extent of the forward pressure arms and the position of the white tab when the boot is in and when it isn't.

Any help will be seriously appreciated.

Are the forward pressure arms extended too far to be safe?
And is the forward pressure still too much to be safe/release consistently?

I haven't ruled out re mounting the heels 5-10mm further back but would rather not.

If you have to ask us, you shouldn't be messing with forward pressure. Take them to a shop

Sod that mate. This is the typical ns response to anything remotely technical. If I had the Rossi manual from 04/05 I would know but I can't find it so Im asking for opinions.

If you don't try and learn/do things for yourself then you will never learn!

Also considering this is the way that my local shop mounted them and it seems to be incorrect I reckoned it might be worth having a stab at it myself.

its because its a HUGE liability.  From what a see though, you have it set too tight.  take it to aa shop that has experience with these.  Alot of places with shitty techs have no clue about the turntables.

Too true sadly. I reckon Im gonna have to get them remounted then. Third centre mount on the same ski so could be curtains for the poor old invaders if this time doesn't work.

Could somebody confirm what the suggested safe range of extention is for the arms?

Is it between the first 2 lines or the second 2?

True, but you're risking your knees here man. If you want to learn how to mount bindings, do it somewhere with proper equipment to test if you did it right.

Looks a bit little bit tight to me. the thing I'd be more concerned with is how your basically maxing out your adjustment arms.

The thing with those binders is that sometimes they fall off and sometimes they don't. I don't mean that in a bad way. They will fall off if you have a crash where your knee twists, they won't fall off if you don't.
I've been riding that model for about 6 years and never once have I come out when I didn't want to. Often, my skis stay on in crashes, but only if my knees don't twist. I don't know about the forward pressure thing, but I wouldn't say they aren't right because they didn't fall off. Also, the din might be set a bit high for you. I am 6feet, 200lbs and ride at 8.5-9. They have terrific retention for their din settings. I used to rock Salomons at 13 or 14 and fell out all the time.

I dont want them to fall off every single time i fall over, that would be irritating.

Ive lowerd the DINs by a half front and back and will try skiign them like that on Monday night. When I next get the opportunity I will try the heels moved back a cm as it seems it would be better to have the arms maxed at the short end than the long.

I recommend taking them to a shop if you really want to be on the safe side. Not just for liability, but because ski shops have a forward pressure device that shows how much resistant pressure the binding gives. Without this gauge, it's really a guessing game.

Buttttt...there should be a small line indentation on the two arms of each heel piece. When the boot is clicked in, it should match up to that. But be careful; too much and you won't release vertically, and you'll pre-release laterally. Too little, and you're pre-release vertically, which never ends good.

Yeah I know the problem needs resolving and I will get it sorted in the next week or so. I just don't want to miss the session on Monday night and for just jibbing around on a few gas pipes on a dry slope I reckon they will hold.

Thanks for all the advice.
