a note for the duke haters...
1. ramp angle - dukes have more ramp than both a FKS and salomon.
duke: 28mm toe, 35mm heel - delta = 7mm
FKS: 15mm toe, 17mm heel - delta = 2mm
916: 15mm toe, 18mm heel - delta = 3mm
2. stack height - by applying the pythagorean theorem to a 115mm wide ski, the effective width is the hypotonuse length.
duke hyp is 127mm
916/fks hyp is 119mm
so that ~6.5% more leverage.
i would argue that you cannot feel this on a ski this wide, and definately not in 4" or more of snow.
so yeah, if you don't dig them, that's cool...
just curious why specifically.

Not hating on the dukes (I like them), but I'm not sure that the hypotenuse length is the right way to compare. Maybe the angle from ski base to boot is more relevant? In either case though, you'd want to use (at most) half of the ski width as the triangle side, not the full 115 mm.

huh, I thought one of the advertised characteristics of the duke was the zero ramp angle?"Nothing like a very, very amorous woman in a leg imobilizer who dozes off every 3 1/2 minutes."

Now that I can't bitch and moan about the ramp angle, what excuse can I use for skiing like shit?"Life's not a bitch. Life's a beautiful woman. You only call her a bitch 'cause she won't let you get that pussy." - Aesop

this does make the difference go to 6.5%.
as far as stack height, the only detraction i have ever heard argued is that it adds leverage and thereby makes the ski more hooky. which i absolutley agree with on a 90mm ski with a +2.5 stack.
the wider the ski, the less it effects things - in my experiance.

wow they have a lot more ramp....
im gonna use a 320mm bsl to convert those to an angle..
duke = 1.25* ramp angle
916 = 0.54*
fks = 0.36*
this means your chest would be about 1/2 inch more forward on a duke than another binding... could be a problem?Best Skier on the Mountain

Did those numbers come from your own measurements or the manufacturers' info? The reason I ask is because Marker's website says 32mm/34mm.
12-12-2009, 07:41 PM #10
but a 2mm delta is still what everyone else is running.

Need a higher heel elevator. Waaaauuughhhhh!!!

Since no one else has mentioned it, the delta for a Duke is completely dependent on what kind of boot you're using. Gliding AFD anyone?

I like your math skills...and let me say that I fucking love both pairs of my Dukes, so y'all haters can go someplace elseMusic: http://soundcloud.com/powtron

(So far, with only 5 days on them, i'm digging the dukes)Preserving farness, nearness presences nearness in nearing that farness

How many people here are actually using their Dukes for touring?

My Dukes set up for my Protons is 34mm toe 36mm heel,probably a bunch lower in the toe with my Adrenalins with the hiking sole but the FKS and 916s only accept a ISO sole so not really a fair comparison.You dont stop playing because you grow old, you grow old because you stop playing

For the measurements entered above, a unitary moment applied at the binding interface results in twice the induced moment at the edge of a 115mm ski using a Duke vs an FKS.
However, is the force really applied at the binding interface? It would seem to me that with a stiff boot and solid boot/binding interface, the moment starts at your knee. That longer effective moment arm would essentially negate the stack height difference contribution.
That's not 100% correct though because why then do racers use risers?
edit: ^^^ My Kryptons/Dukes measured similarly. ^^^

Correct me if I'm wrong but does it really matter that the AFD moves up and down rather than the toepiece moving like a solly? The top of the toe lug on the boot remains the same no matter what you do with the AFD so the AFD movement has no effect on ramp angle. The AFD movement seems ideal to me. For example swapping soles on Adrenalins from the lugged sole to the DIN standard all you need to do is move the AFD, the ramp stays the same.
I like my dukes. i just wish the didn't eat away at the toes of my Garmonts.Being grown-up sucks!

I just got a pair for resort/side country use and noticed there is some play in the toe piece fore and aft when there is no boot in the binding. Any one else notice this?
