But what appears to be a serious design flaw in the Intelligrip Transition skins has rendered the ski/skin combination unusable for me even before I could put them on snow.
The leading end of the Intelligrip Transition skins relies on a vertical plastic peg that slides into a through-hole in the ski. That fitting is extremely tight and snaps into place. During skin removal, pushing the pin as directed (requiring great force) only partially releases the peg. Complete removal requires either a) continued narrowly-applied pressure to push it through the hole, using perhaps a pole tip or b) an additional pulling force from the base-side of the ski. Unfortunately, the latter approach was enough to completely rip the peg from the tab into which it is affixed. That peg/tab junction simply lacks sufficient reinforcement for the forces necessary to fully remove the pin. My first attempt significantly weakened that junction. My second attempt, despite great care and on the other ski, caused it to fail completely.
The ski itself may function well as a waxable ski, but this area of the skin, and perhaps the recessed fitting on the ski as well, needs additional thought and refinement (or a complete redesign) by Madshus before I would trust this system.
One workaround may be to simply drill out the fitting to relieve the fit of the peg. It looks like reaming it out just slightly (to 1/4") may do the trick without compromising the overall fit of those parts. Considering how difficult it appears to be to purchase Fischer's E99 Easy Skin Xtralite in the US (the alternative I've been considering), I may just have to proceed with making this M55 work. I'll post back soon.
