Can someone verify and explain what exactly is the differnce between Forward pressure and DIN?

and in a given scenario like this..."you make it over a jump, and you make a good landing but the skis pop off right on impact (bindings in good condition)", should you increase the DIN or forward pressure to prevent it from happening?

din is the tension on the spring in your toe and heal, the forward presure is the spring in your heal track and is usually adjusted by a screw and when you click in it should be flush or between impinted lines. If you dont feel comfortable doing it i would take it in to the shop. You need some forward pressure to keep your boot in the binder so the din actually works. im assuming the kids who are 145 and have there dins on 14 and claim they need it have no idea what forward pressure is.

Din = how tight the springs are in your bindings which cause you to pop out of your ski, higher din = less to no pop out and f'ed knees(depending on weight)

Forward pressure is the adjustment on your heel piece, and it is how close your bindings are to your feet. If your forward pressure is too far back you will pop out easier.

any more brain busters?

So basically, if I land and skis pop out I should adjust the DIN?
What if I'm just skiing normally down a hill and the skiis come off when i ski with some speed, do I adjust the forward pressure or still the DIN in this case?

Depends, whats your din at and whats your height and weight and boot sole length, and to check forward pressure just put your boot into your toe piece, then go like you are gonna pop in back stop when you hit the brake and see how close you are to the heel part that pops down, you should be very close to that.

you need a balance of din and pressure. if your skis are poppin off when your goin straight and your din seems right then its forward pressure, if you cn ski normally but when you spin your ski flys off and hits a kid in the face .. thats Din.

if you want to do it right, on solly there is a piece of metal in th eback with 2 arrows, when you step into the binder the arrows should line up in the middle of the indent or the lines on the side. on look rossi the screw that makes forward backwards adjustments needs to be flush when clicked so adjust it then click in, dont crank on it with your oot int he binder or youl strip something.

Ohh God you are so wrong. DIN is the spring tension in BOTH the heel and the toe. But it is absolutely useless if your forward pressure is set incorrectly. Forward pressure just has to do with how well your boot is fitting into your binding in a lateral sense, if that makes sense. Forward pressure is how much pressure you binding is pushing back at you boot with. Depending on what company of binder you use there are different indicators as to the forward pressure adjustment. Usually and arrow or line must be within a certain range WHEN THE BOOT IS IN THE BINDING, for some reason a lot of people forget that part.

some companies make it as confusing as possible, i think so you dont try to mess with it on your own, or mistake the fp screw for the din screw. shop would probly adjust it for free though.

i learned this lesson the hard way back in my racing days... i was doing a super-g course and as i was turning around the 6th gate my outside ski decided to pop off, it was a bit painful... but yea my DINs were set to 13, i came to find later on that the forward pressure was not set correctly. i'd recommend going to your local shop, if they have any sort of soul they won't charge you, and they'll get it set correctly.

When a shop sets your din, they are required to set the forward pressure too, right? I have the rossi axial2 and when I click the boot in a I don't see the red line in that yellow box under the heel piece. I wonder if they even did it.

too bad you're in Quebec, or I wanted to ask what good ski shops should i visit in Vancouver, cause the only one close to my house is sports chek, which isn't a winter sport specific shop. their price is usually effing rip offs, highly doubt the tech knows much about stuff either, or des it vary from each store?
