Another DIN question

post #1 of 16
Thread Starter 
Does anyone have a copy of the DIN setting chart?

My friend and I are going skiing on Saturday, and I'd like to set her bindings for her before we go. Since there are no ski shops anywhere near here, it isn't possible to set them before we get to the hill, and quite frankly, I don't trust the teenagers they have doing that. Nothing against that age group, but they aren't very knowledgable where I'm going.

She's 5'4", 150 lbs, age 40, and is still a novice. Two years ago she spun out, hit me, tossed me into a tree well, and tore her ACL. Her skis never came off. The DIN was set at 3.5.

She hasn't gone since, and she's ready to go now, but I want to be sure she releases out of those skis if she needs to, to assure her a fun time. [img]graemlins/thumbsup.gif[/img]

One piece of info missing is her boot sole length.

Thanks, guys! I believe she's a size 6.

I smell a fracture in the house. Get thee to a good shop and spend the $15 to have the pro's do it.

Vita-man is right on. Your friend's DIN should be in the 4 to 5 range according to the chart and that's if she is a Type I skier. If her binding wouldn't release at 3.5 there is something wrong with how it is adjusted or with the binding itself. Have them checked out by a shop that has the proper equipment. Out of curiousity, do you know what binding model she has on her skis?

Bonnie, I like how you quote Einstein, but you certainly are not using his guidence. Take your friends skis to a shop, they have the requirments from the manufacturer on how and what the proper DIN settings should be on ALL equipment. I suppose you do your own brakes and such on your car, did you perfom the ACL surgery on your friend also???

YIKES!!!! :

She has Tyrolia 530 bindings. They used to be mine. I never had a problem with them and I skied with them until 2 weeks before I sold them to her.

She had a strange fall, and was not in good physical shape, and quite frankly, you can break a leg or tear an ACL just by jumping wrong in a basketball game.

skialta- Not to be defensive, but yes, I DO most of my own car repairs when I can . I also do home repairs. Some people call a plumber when the toilet runs. I call a plumber when I don't own a big enough pipe wrench. I'm incredibly handy. Some of the guys I've called for certain things too heavy or complex for me had trouble finding their own ass with both hands. This doesn't lend me to confidence in "professionals".

The guy in the shop is going to look at the same chart, ask the same questions, set it the same as I would. The nearest ski shop here is in Chicago. I doubt it's worth the 4 hour trip for her.

There is a ski shop about 90 minutes from here. When I wanted bindings moved on a pair that had bindings on them (to accomodate bigger boots), they refused to do it. They had only been mounted once. They said if they don't sell them, they can't move them. Something about liability. So make sure your mechanic sells every brand of car and part before you let him change your brakes. Riiiiight.

With ski shops like that, I will trust myself. I'm not dead yet.

Nice one Bonni While everyone always says go to a shop the fact is about half the people on this forum don't even follow the DIN charts and crank their bindings up themselves. Adjusting bindings is not rocket science, but there are a few things you need to know, especially surrounding forward pressure. In the frantic scramble to avoid getting sued legitemate questions like this are met by unhelpful replies which is just sad.

ACL tears and bindings are not yet related, although there are "suggestions" by some manufacturers to the contrary. Ask them for the research that leads to their advertizing claims - NADA - even if they actually believe what they publish. The fact that she had an ACL tear probably has zero to do with the binding.

Nevertheless, considering the stakes, it might pay to have these suckers tested in the shop.

EDIT: P.S. Even so, Bonni, you are a most resourceful and capable woman, and given the right tool, you probably can accomplish almost anything.

The Din indicator on the binding is only a starting point for adjustment. Once it is set there it is placed in an apparatus ( like a huber --electronic with all the newt meter etc) that will simulate the toe release and heel release , with a simulated foot . If it does not corralate to the real relaese setting then binding is re set. For example the binding is set at 5 , but the actual release is at 4 , then you have to crank the bindings up (maybe 6) and start the whole ck again , untill it "ACTUALY" releases at the proscribed torque for that din , regardless of what the din indicator says.It is like a speedometer in a car, on the whole they are not super acurate " gee officer my speedometer said I was only going 54"Also if the forward pressure adjustment is not done correctly then it changes the release factors and that can vary on same brands like Marker has some models that it had to be flush and the other model had to have one ring exposed.As far as acl injuries , they have gone up in the last few years , but not because of bindings , but because of shaped skiis that want to keep on carveing while the skier is falling (put simply).

UPDATE: Iowa Girl Does Well.

In today's news, Iowan Bonni, avid Epicski reader, took a friends skis to the Mountain ski shop for a DIN check after setting it herself. The man that was to set the DIN asked the same questions of her friend that she did, measured the sole length, and for some strange reason, they were right on the money. All parties were pleased with the outcome. No further adjustments were necessary to the bindings, and everyone went out and skied happily all day.

The friend fell many times, and each time, the bindings did their job. They came off with reasonable ease.

End of story.

I agree with Oboe - I took a very nasty spill last year and twisted my knee very badly. I was extremely fortunate in that the only real damage was to the muscles around my knee, and not the ligaments. However, my bindings were set at DIN 3.5. They did NOT protect me from what could have been very serious knee damage. It's not the bindings. My suggestion is to stay balanced, out of the back seat.

As someone who does a lot of work on your car, you're bound to know that you need the right tools for the job. You don't remove spark plugs with a screwdriver, do you?
All binding mountings are supposed to be drilled up using a jig which is set to your boot size. For a shop to move a binding, it needs to have the jig for that binding. If the shop doesn't have the jig, then it is virtually impossible for them to drill the holes in the right place. Surely that is obvious! Or would you prefer them to guess?
Please, don't blame the shop for wanting to do a job right.

Unfortionaltly the some forces that contribute to ACL injuries (skier in the back seat) are not exactly the same forces that cause a binding to release. The toe piece has no mechanism for vertical release. This is why it is not all that uncommon for ACL injuries to occure with no binding release, it does not necessarily mean the binking was improperly set or there was any malfunction.

That said, I would agree with others who have advised you to have your friend get to have them set at a shop just to make sure they are funtioning properly, expecially after such an injury where malfuntion is a possibility.

Someone at a ski shop can use any jig to drill holes correctly and at the right position. It just takes longer as they will need to make sure the holes will be in the right place. Bonnie' issue appeared to be with a number of remounting. They may have been concerned with the structural integrity of the ski.
