Padded foam strips for SL skis?

post #1 of 25
Thread Starter 
Anybody use the self adhesive foam strips to protect SL skis against delam from gate impact, and if so do they work?

I’m tired of delaminating my skis.

Gracias.

We used to use silicon cauking. It doesn't seem as popular as it once did though. There was a college race at my Mt. this last weekend and I did see a dozen or so kids with the foam strips on. My Spauldings had a metal layer on top that the break aways would get under and peel away and the silicon put a stop to it.

Never heard of any foam strips or use of silicon to stop skiis from braking. I have just seen plastic protectors on tips of racing sandwich skiis in TV and at shops. My Head iSL RD doesent have anything in front but I dont run gates so maybe it doesent matter. If there is still a risk for delamination I would offcourse do something about it. Recomendations?

The foam strips are about 2' long and are placed on both sides of the top sheet edges to protect the ski from a rapid gate impact after shinning it off. If you don't run gates there is no issue.

Anyone use them?

I don't know if it is as important with the shorter skis, but if you are running gates you absolutely need to protect your skis to avoid delam. or cracking the top sheet. I always used caulking because it was around and was free for me. The rubber or plastic strips would likley work well too. I learned my leason long ago when I cracked the top sheet on my first set of race stock Volkl p30 within the first week I had them. Better safe than sorry!

If you don't run gates don't worry about it. The impact of the gates on the front half of the ski is what the rubber or silicon protects against.

I seem to have more delam issues with the shorter skis than I ever did with the old 203-205 SL's.

I delam'ed my brand new 6* on the third run through the gates (first day) ... Luckily my local shop replaced them with another pair off the rack - doubt that would happen again.

Interesting... I was just guessing on that one. I was thinking in terms of gate contact- on old school skis I would mostly notice gate contact on the forward half of the tips and thought maybe short tips would = less contact... who knows.

For gluing silicone is not the best thing arround. MS-polymer is a much better glue. But is it enough to just glue some foam stripes on the tips of the skiis?

High density polyurethane weather strpping works well for rapid gate protection. I used it in the past. It was more of an issue when 'shinning' was the prevalent way to move the gate away. With cross blocking, the gates hit the skis less. Go to any home hardware stare and buy a small package for a few dollars.

I'd definitely agree with Betaracer. My friend has his weight back more when running gates, so his shin contacts the gate first most of the time, and his skis get really chipped away over a season. Mine don't get messed up much at all, since I tend to crossblock waaay before I shin, so the gate doesn't snap down as fast.

Also, it seems like volkls accept the wear worse than say, atomics. The sandwich construction just isn't as durable as the b4 + aerospeed.

Betaracer,
Can you give a more detailed explanation of old vs. new slalom technique? I have been on shaped skis since I was 13 and never really learned high-performance technique on straight skis. It has always intrigued me...

Well, I tend to meet the gate so that my shin and fist/pole guard make contact at about the same time. Sometimes it's a true shin-off, other times it's a hand guard clear. It just depends on the turn/course set.

If you're haulin through a course I'd find it hard to believe you're not getting ANY gate slap on your skis. If so you're doing something wrong or not going fast enough. (please don't flame me - just watch a World Cup and tell me they aren't getting any gate slap ... sometimes so much that they lose the edge).

Regardless, I still get the viscious gate whack - not everytime, but enough so that it's an issue. However, I notice a lot more wear & tear on the shorter skis than on the longer skis of yesteryear. Maybe it's because the force is focused more on one ski (wider stance), or because the skis are wider (higher off the snow when it's on edge), or because you can be way more agressive on your line ... whatever the reason it's an issue.

I was thinking about using the weather stripping, thanks for the info.

What is weather stripping?

It's a rubber strip that is placed on doors and windows to form a seal when they are closed. It prevents wind and cool air from coming in, as well as hot air from leaving the building.

Foam weather stripping used around windows and doors etc that has an adhesive backing can be found at just about any hardware store. The question I guess is if what is readily available is dense enough for the purpose we're discussing, and if the self adhesive is sticky enough to work on skis (cold temps, etc.).

Ok, now I know what it is. But where do you aply it? Over the whole length of your ski on top in front of the bindings on both sides? Or just in the front? Delamination starts from the front doesent it. Wouldent it be better to put on some kind of U-shaped plastic that was glued and bolted to the ski tip?

No, delam can start from the middle of the skis - especially the kind I'm trying to stop.

Yeah, I definitely get some gate wack, but not as much as my friend does. Also, our team's practice gates are really old, which means the rubber hinge things at the bottoms are less elastic. So our gates don't come down as hard as when I'm racing on newer gates (nor do they come up as fast. Some completely new gates HURT to race on). It seems like I actually get more gate whack when I get slowed down in a course, but as you said there are a LOT of factors (speed, angle, technique, line, gates, temperature, snow conditions etc. etc.).

wodee, ok I see. But do those help protect against delamination or just scraching and beating in general? Dont they also change the way the ski performs and behaves?

They are meant only to protect against delam. I would imagine they cushion the gate impact by distributing the force over a slightly larger area across the foam, and deaden the blow.

But, since I'm the one asking how well they work I have no idea if they do ... I ordered some so I'll let you know (Artech sells them for $4.00 - Saves me a trip to Lowes).

I can't imagine they change they way a ski behaves in any way as they are very light foam padding - effectively just a big thick sticker.

I don´t know for Atomics but, afaik, the cohesion of the layers has always been a problem with sandwich skis exposed to gate impacts.

Nice fat bead of bathtub caulking worked for me. I don't think shorter skis make a diffence. If that was the factor than the gate would be landing in front of the ski and you would then ski over it. OUCH. No doubt there are better products but as mentioned above the caulking is cheap, easy, readily available and effective.

Since it was asked, I can comment on the issue of why the gate clearing technique is related to the delamination problem. When gates are cleared by hand impact, contact is up on the gate shaft. This impact pushes the gate over and creates a "whipping action" due to the flexibility in the gate. The resulting gate impact velocity as felt by the ski is the combination of the velocity from the gate being pushed over plus the whipping velocity. This combined velocity is much greater in the case of shinning as the impact point is very low on the gate shaft and the push down velocity becomes greater and by my experience, the whipping velocity a lot faster than for the case of hand/pole clearing. Someone has probably done a study on this and can make comments, but this is what I see.
