I just love saying "Holy Thread Resurrection"

You've heard of a "split tail", how about a "split nose and tail". Split middle too. Can soften the board(s) but keep'em torsionally rigider.

want to see an asym in action?
man, very impressive riding, very impressive.....

Fastskiguy- Maybe if you made a singlespeed snowboard, it would have more soul, more authenticity, and be a proverbial sign for "My bawlz are as big as my 700c wheelset"
I'm building up a (soulless) 26'r now....I'm thinking the little wheel might be faster. Stronger, stiffer, and spins up faster. I've been on 700's for awhile but my climbing has just sucked in recent years. Might be just getting older...but I'm blaming the bike for now.
You guys remember the piezoelectric ski damping thing from awhile back, right? It had a little light that blinked on and off. Supposed to be really smooth. But then everybody decided it was a gimmick. But what about the extra rubber layer on the toeside or something?
-
One factor that affects the tendency to chatter (besides too much spare time and opinion) is the ratio of moving mass to the spring and damping forces opposing the motion. On heelside, the lower leg has to move with the board since ankle flex can soak up only a small fraction of the impulse due to the short offset between ankle joint and heel edge. On toeside, the ankle flex can absorb more travel, so the lower leg doesn't get launched so hard with each impulse. The momentum of the moving lower leg is absorbed by the upper leg and core muscles, which are equally powerful on either edge (more or less). Boots have a fair amount of damping (friction) in the flex, so the ankle flexing soaks up a lot of the impulse that otherwise would launch the board off the snow. Less boot flex results in less damping effect. Therefore, on heelside you have more mass and less damping, so the springs get worked harder, the natural frequency of the bounce is lower and the amplitude tends to be larger.
Think of it in terms of vehicle suspension: heavy wheels, short spring travel and stiff shocks versus light wheels, longer springs and softer shocks. On really smooth surfaces, the former (heelside) might pull a little higher cornering force, but as soon as it gets bumpy you need more compliance and less unsprung weight to keep the rubber on the road or the steel on the ice.
Makes sense but I chatter the crap out of my toesides compared to heelsides. Maybe I need to run a reverse bilateral asymmetrical board!
-
They work but not any better so why bother ?
We could run piezoelectric stuff inside and have a different frequency damped on each side then market the hell out of it. Just trying to think outside of the box here :) All we'd need was a couple of world cup wins.....
-
Okay, so we're talking about the same thing, regardless of terminology. (or lack thereof! :);)) Again, I ask you by what sense of the word does that not constitute an asym?
I'm pretty sure that his definition of "asymmetrical" is specifically one sidecut a little farther forward or back than the other. I think he's considering boards with different flex/damping/sidecut radius/running lenth on each side as "not asymmetrical" as long as the center of the sidecut is in the same position on each side. I'm sure he can elaborate, I probably shouldn't speak for him.
I'm going with "if one side is different than the other then it's asymmetrical" so a board with an extra rubber layer on one side is an asym, even if the outline is symmetrical. But only because the board is different on one side than the other ;)
Purely semantics, right? Asyms will rule again someday!
-
here is a goofy asym that can also be ridden regular if you want to
I thought that binding setup came with a torsion bar! ;)
-
If one sidecut isn't ahead of the other, than the deck is not an asymm.
you're confusing dual radius sidecut with asymm.
I'm glad we're finally down to semantics and that's a good thing :)
-
Asyms.
I need to get back on that PJ sometime this year.
Keep an eye out for the violet rose topsheet making a return sometime in the near future. Not an asym, but something just as funky...
Jesus is goofy? Really?
-
decks need not be re-engineered so that one sidecut is ahead of the other,
I'm not sure that's the next direction for asyms...they did that awhile back and found it wasn't so great. Maybe the next direction will be a tighter sidecut on the toeside or softer flex or and additional rubber layer or something. Maybe the length of the edge will be shorter on one side than the other. Heck, if I knew I'd be rich I tell you! There are a lot of ways a board can be asymmetrical, not just where the sidecut is located. The reason I think it'll be back in some form is simply that our toesides and heelsides are so different, it would have to be some freak of physics if a symmetrical board was the ideal shape for both.
-
Look at the fact that board design ha moved to all-symmetrical.
As long as we ride them diagonally or sideways, we will bias our body position, regardless of board profile.
Perhaps the fact that all modern skis are now patterned after symmetric racing snowboards ("shaped" skis) is equally overwhelming to you?
We're more likely to see variations and evolutions of body mechanics than of board profiles, as the board, itself, needs to interface symmetrically with the snow.
Skis are symmetrical because our turns on skis are (supposed to be) symmetrical. It's the bias in our body position on snowboards that makes asymmetrical boards theoretically better. You might say "but it's a fact that asymms suck" and obviously it's true but just because in the past asymmetrical boards have been eclipsed doesn't mean they always will. It just seems so obvious that these turns are different so the board should be a little different on one side than the other.
-
But my center of weight definitely tends towards the tail on toesides, and tends towards the nose on heelsides. Does nobody else experience that, really?
Just want to report that I experience that.
-
I think the case for asyms in theory is simply overwhelming. All you have to do is look at any high level rider on a heelside and toeside. It's asymmetrical. Most of you guys are doing some kind of crazy angulation on heelside whereas you just can't contort your body that way toeside. The body position during the turn is not symmetrical. Thus the optimal board shape and flex isn't either. I think it's fair to say we don't understand what the best shape is....but clearly it isn't the same. Maybe we're in a phase where designs is progressing rapidly on symmetrical boards and that is a good thing. But ultimately asymmetrical boards will prove to be superior.
-
Not to beat this one to death,
You know, I think we'll see the return of the asym board someday and a lot of these naysayers will be eating a small amount of crow. Why? Because...as many have stated...the toeside and heelside turns are a lot different. They just are.

Human nature won't change, but it'll make it a lot more difficult for human nature to carry out certain acts, for example:
I guess I'm pro-gun but I don't live around crazy people. If 99% of people are responsible and some goof ball opens fire and kills somebody for spitting on the sidewalk or something, well, that's a bad deal. I'm sure nobody on this board would think of shooting at someone because they look differently or act differently but there's a few nut cases that would, they're just looking for the chance to screw with people. So I think it's a valid argument...make them harder to get and you lessen these types of situations. Of course, disarming your law abiding people is a bad deal too. Thus the controversy!

Dog identifies problem.
Just wanna throw some props out to the dog in this case! Way to go!

Keep in mind that this is the wild wild west. Landowners have no reservations about utilizing firearm with people trespassing on their land let alone ripping you off. Im all for it, mandatory training for all non felons and a fire arm for them. Douche bags will think twice about entering knowing that someone in the house has been trained to use a weapon. Call it a conscript anti douche bag army. Whats mine is not yours!
Absolutely, 100%, totally agree.

why do they call them dum dum bullets?
-
I can't believe they let you keep the rod and screws!!! Hell Yeah!!
I think it's a law or something, otherwise you have to send it in for histopathology. Maybe it's just a rumor I heard.
But...it's pretty cool to be living now, they can put you back together again. Cyborgs!

What a great story, way to go Fin!

I can see Luke Skywalker in one of those grooves with my middle eye!
I was trying to come up with something witty but....this is much wittier.
It's funny...cross your eyes and relax...wow!

who cares, I want to see the sex robot...

i only get to see snow 2-3 times a year now
. there is a little snow in tucson every now and again :oMaybe you'll see snow in chicago this winter?

A little embarrasing...

This sounds like good advise...and I'd like to add that going straight used to be a problem for me too but now it's easy and all I did was ride more. But I like the idea of standing in my gear for awhile to see what's twisting or stressed (hopefully nothing!)
