Head I.M. 88 sidewall problems

post #1 of 16
Thread Starter 
Hi all, I'm new to the site, but i must say i'm addicted to it already so i thank you all for that, I guess. Anyways I got a pair of the I.M. 88s last year about halfway through the season and loved them. I was working in alta last winter and the skis performed amazingly other than the fact that they lasted for three weeks before the sidewall blew. I was wondering if anyone else has had the same problem with these skis. Oh, i forgot to say that the sidewall damage was not rock induced. I would also like to add that Head just sent me a pair of the 07's so i can't say anything bad about their warrenty dept.

Thanks for any input...

I would think that it can happen with any ski, fluke. I only ski Head and its all been great. But glad they took care of you, I really like their customer support they set me up with replacement buckles for my race boots free of charge.

I had it happen to me twice. I had my 1st pair for three days before they blew. Head replaced them and they blew again.

Again they have replaced them. My rep told me that they have had major issues with this model.

Great ski but am put off by how weak they are.

Having said that I was happy with head replacing them so I am going to the Head Super Mojo 105 to my quiver for next year.

I cracked a side wall underfoot on like the 3rd day out, shanking a rock at speed. Repaired. Somewhere around 15-20 days, I split the core on one tail....hope this years are more durable.

I wouldn't go as far as calling it a lemon....think they just went to a new design and didn't sort out a few weak points. Specificly:

1. Thin sidewalls. I cracked one on mine, and have heard about many others. However, this is a common issue on skis like this, stocklis are very similar in not having super-robust sidewalls.

2. Delams': My housemate had his pair start separating the lower Ti sheet from the sidewall....he's pretty agressive though.

3. Breakage: Mine split in the tail due to too much force (not impact, just loading the tail hard). The core just sheared apart. I think this is due to the relatively soft flex and the very strong "liquid metal" Ti used in the skis - it can flex alot without bending, thus puttting a ton of stress on the other parts of the ski like the core and sidewall.

Aside from that, they are the best ski i've ever been on....hope the '07 are more durable.

It sounds like whatever fuses the sandwiched layers (epoxy, heat, etc) is not quite elasic enough considering the soft flex of the ski. It seems to be a semi-common problem among race skis, and since those skis are built like race skis it makes sense. I had it happen with 3 pairs of Elan GSX's a few years ago. Elan finally got it right by changing how they were attaching the topsheet. Highway Star, did you get Head to warranty those skis after you blew the edge on a rock or was it on you?

Highway Star brings up an interesting point about the sandwich const. of the Heads and Stocklis. My two roommates and I were responsible for killing 5 pairs of skis last year all of which had the sidewalls blow. 4 of the 5 pairs were Head or Stockli and none had significant damage to the bases. I’m not trying to rip on either of these brands, but I hope they are able to work out these problems. I for one will be skiing primarily the 88’s until they stop production or fail to warranty them if this defect happens again. The skis were fast as hell and stable in pretty much every condition imaginable. I was lucky enough to borrow or demo a lot of skis last winter and it only took one run on the 88's before i decided i was going to own a pair. I can only recall a few days at Alta last year that I would have preferred a bigger ski, but that’s why I hope to get my hands on a pair of the supermojos for this season.

If anyone wants to know about how these skis handled in specific conditions ask and I shall tell.

both the head and the Volkl mantra had a similiar problem. If you bevel the top sheet from tip to tail you should be fine.

Bevel the top sheet???
post #11 of 16
Beveling the top sheet.....no.

Mine will be warrrantied, I need to get them back to the shop where I got them. I didn't claim the original rock shot as warranty, but the tail cracking definitely is.

Top sheet 'profiling' is a better term and is VERY good advice for any vertical sidewall ski. It won't keep the sidewalls from cracking but it prevents cosmetic chipping of the topsheet. It also allows the ski to knife through snow cleaner when at extreme angles. You peel back (or file) the edge of the topsheet at a 45deg angle it keeps the edge of one ski from tearing into the topsheet. It also reduces drag as the ski is on edge.

Sidewall skis aren't as tough as cap construction. If you want durability get a cap, if you want all out performance sidewalls usually out perform caps.

Stockli wouldn't claim their skis are 'tough', just that they perform, and they do.

Is it recommended to do this with a specialized tool? I have noticed some chipping on my new GS skis where it has made contact with the other ski's edge.

So...would you all suggest that I mount the Monster 77's with tyrolia bindings (I have the flat ski) as to increase my warranty to two years? Or if something happens, do you think it would occur within the first 40 ski days of the ski?
post #15 of 16
There is a special tool for topsheet profiling but I use a bastard file, works fine just takes longer.

I wouldn't worry too much about binding choice for the 77, but it will double the warranty.

edgewise in stowe profiled my 103s & have had nothing but good turns fron them (hope to beat them more this winter w/ more snow!)
