Hello armada ARV 86

can someone tell me how many cm from ski middle is the freestyle recommend?

thanks


like on the line TW the recommended line it’s -2cm
why companies not simply set a mark for Ski middle center 🤷‍♂️

A good bit a of modern park skis aren’t designed around a dead centermount, some skis it may even hinder their performance depending on length, flex, side cut, etc

It's easy to measure it yourself. Just measure the true length of the ski, divide it by two, and there's your true centre.

I usually do -.5cm but I'd recommend anyone do anywhere -1 to center mount for most park skis. More park and switch you do, the more centered but even -2 is fine for rails and hitting jumps switch.
Slightly unrelated but racers are finding more centered mounts give you more edge hold. Nothing extreme but I know people doing like +2 factory recommended. Soon they'll realize skiing switch is more aerodynamic and make twin tip downhill skis.

I just want to point out that if you are riding Pivots with a center mount, you have effectively a longer tail than the tip. The heel piece is shorter than the toe. When you are clicked in, the area from tip of toe piece to back set of screws of heel piece doesnt flex, so if you are mounting dead center with pivots you are going to end up with less effective tip than tail. Worked in a shop for a few years, always measured out center mounted pivots to check my math. If you measure to the end of the plastic forward pressure bit on a pivot heel, the toe and heel are the same length but bc ski can flex under the heel piece behind the rear set of screws, you end up with more tail than tip.

The length of the binding doesn't effect mount point. Mount point relates to where the centre of the boot sits over the ski, so a ski mounted at centre will have the centre of the boot positioned exactly over the centre of the ski. No matter what binding you're using. Take a look at a Look/Rossi mounting jig. You're still referencing off the same centre mark on the jig regardless of whether you're mounting a Pivot, SPX, PX Race, etc.

If this would be. Everyone who ride pivot like Harlaut and co would ride longer tail then nose 🤷‍♂️ If you put your boot center on the center of the Ski it doesn’t matter you will be center. What means middle Soul of boot on center of ski it’s the result Same size of nose then tail 🤷‍♂️

the question is if it makes such a big difference then -2cm behind center. For an only park ski 🤷‍♂️🤗

Ya it doesnt effect the mount point, that's not what I was saying. My point is take that into consideration when choosing a mount point bc if you center mount pivots, regardless of boot size or whatever, you're going to end up with a slightly smaller amount of tip. It's because on most bindings the screws in the heel aren't directly under the heel, they are behind the boot, so the heel piece is longer and the tail is shorter.

Oh yeah I get what you're saying now, and yeah if you were to measure the distance from the screws to the end of the ski then the tail would end up slightly longer than the tip, but that measurement in particular doesn't really mean anything with regard to how the ski is going to ski. It's probably more relevant to measure from the end of the boot to the end of the ski, which will still be equal when mounting at centre.

The length of the toe and heel pieces has nothing to do with it what the fuck are you talking about 😂😂 the mount is based around the boot center, so when you mount true center with a jig, assuming you do it correctly, there is an equal amount of ski in front of the middle of the boot and behind the middle of the boot

I am madly in love with mounting my skis exactly 1cm behind dead center.

i once tried -2 and it just didnt feel as symmetrically balanced as -1cm. I think dead center is fine too but im too happy with -1cm to bother switching

Okay is there anyone who means center mount it’s less stability on bigger jumps and higher speed?

Remember not for slopes. Park skiing only !!!

If you prioritize switch performance and rail performance, go true centre. For more stability taking off and landing forwards, maybe go .5 to 1cm back. But honestly they'll be perfectly fine either way.

in my experience it can affect the flex of the ski weirdly because the tail is longer but to each their own

Yes you will end up with the same amount of ski in front of boot center as behind boot center. But from the front of a pivot toe piece to the back set of screws in a pivot heel piece, the ski cannot flex when you are clicked in. So when you are skiing down a run with dead center mounted pivots, there is a longer amount of tail that is able to flex than there is amount of tip able to flex.

Uh, dude, literally the whole purpose of the Pivot heel design is to maximize heel elasticity and give you a smooth flex underfoot. If you don't believe me, click your boot into a ski with a Pivot and then give it a hand flex and watch the way the heel moves to allow the whole ski to flex evenly. Or alternatively, have you ever skied the same ski back to back with a Pivot and a demo binding? You'll get a way damper ride and better edge hold from the Pivot.

I ride -1.5 from center on my park skis and I really like it. My last 2 pairs were center mounted.
