I apologize for long-winded post- the later I write and the more tired I am- the longer it takes me to get to the point!
It appears at least some of what I am trying to say is getting lost in translation.
Shenanagains- you are entirely missing my point. I did not intend to suggest that “no changes are allowed”- or that I am opposed to R&D and continuous improvement of ski technology. I am very much the opposite. And I was certainly not trying to suggest that being old tech is a defining characteristic of XCD.
My point is purely that if “XCD” is downhill skiing on xcountry technology- then Nordic tech that limits xcountry striding performance, in order to maximize downhill performance- is not “XCD”.
I don’t own the word or phrase “XCD”- it obviously means different things to different skiers in different skiing contexts.
But- I interpreted the point of this thread was to explore XCD in a classical sense: DOWNHILL SKIING ON XCOUNTRY TECH. No?
This has perhaps gone off the rails- and unfortunately I have contributed to it. Perhaps we need a “What is XCD?” thread to continue this debate?
I agree with you entirely- there have been 3 ½ decades of progress in Nordic ski technology (one could argue that there have been hundreds, if not thousands of years of XCD progress!). I don’t agree that the classical working definition of “XCD” “flies in the face” of progress…
I did not mean to suggest “no sidecut”. What I mean is that not every ski needs it. The trend is to add parabolic shape to almost every ski- regardless of application.

True powder skis don’t need sidecut- sidecut is for turning efficiency on hard/dense snow (that was my point).
Parabolic sidecut on a ski like the Vector makes sense to me- it is a “jack-of-all-trades” “alpine touring” ski. And I know from personal experience that it is strong and rigid enough to hold a powerful and stable edge on dense consolidated snow.
Have you ever tried to put a ski like the Guide/Annum on edge on dense/hard snow? It’s a bit of a nightmare- even with powerful boots-bindings- that ski twists, bounces and jumps around like a wild horse! A ski like the Guide/Annum is so obviously designed for XCD-skiing in deep soft snow. My point is- I think that Karhu may have gotten it wrong…the Guide/Annum loses a lot of its effective flotation because of the aggressive sidecut. I think that the Guide/Annum would be a better powder XCD ski if it had less sidecut and more width underfoot.
A different example is a xcountry ski like the current E-109. The current E-109 has more sidecut than the S-88!? Why? I don’t get it. If the primary reason to grab an E-109- vs. an E-99- is to get more flotation in soft snow- then why give up all that effective width to make the E-109 easy-turnin? IMHO, the E-109 would be a better mid-width XCD ski, if it had less sidecut. Fischer already has the turn/climb-orientated S-Bound lineup- why does the E-109 need a parabolic profile?
And back to one of your other comments- a powder XCD ski obviously benefits from tip rocker. Looking at the Guide/Annum again as an example: if I were to redesign it (with “new” tech)- I would give it less sidecut and a fully-rockered tip (but keep the traditional single camber underfoot- for K&G).
Camber? Did not mean to suggest that I am opposed to single-camber in “XCD”. Single-cambered xcountry skis have been around for thousands of years. IMO/IME, a single-cambered xcountry ski will always be a better choice in deep, soft snow than a double-cambered ski. But, can I assume that everybody could agree that a fully-rockered ski can never offer true xcountry performance? How can you possibly get a Nordic “kick” with no camber underfoot?
I am not opposed to any of the materials or technologies that you mention.
I am just trying to work with the classical definition of “XCD” that LJ started with.
And back to that LJ- I have no idea how wide a ski you can effectively downhill ski on xcountry boots-bindings….
I have skied skis wider than the Guide/Annum/S-112-BC110 many times (e.g. Vector BC/BC125) but I have always used plastic boots and “Telemark” bindings.
I too am interested in what you can achieve on xcountry tech!
Are you going to mount NNNBC on the Kom!?
(And- where in the world is "Jakku"? Is that real place, a secret code name, or were did you have to make a trip to the Star Wars universe?)
