Alpine Snowboard Plate Systems

I sure some one will figure it out.. why would you want a board that looks like swiss cheese! I mean your gonna have a bunch of holes... Vist Holes, Apex holes, Hangle Holes.. Mass Holes... I threw that in.. its not really a plate...yet..

I think ApexComp. holes are equal to Hangl holes so one set less

[bjvircks]

I don't see 4x4 being ideal for this sort of thing.

absolutely right... follow the forces and minimize redirection and dissipation. Attachment of the plates right along the board edges makes the most sense because that is where the force needs to be directed. That is where the force will ultimately end up, regardless... because that is where the board gets its reaction force, the edge engaged in the snow.

I think 'plates only' boards would be best served by migrating to an insert pattern out at the edges.

or is it?
pics to come once I get everything in place. my starting point is a hangl, a dead board and a headache.

Sure would be nice to be able to use the old 4X4 pattern so it could be used on existing boards without the other inserts in it though .......

well, you could use a Vist as a starting point.........

solid carbon,a little flexable,25mm high with the plate,

Hi Roby - nice looking plate from what we can see so far!

Have you had any issues with the durability of the carbon fiber plate?

I have to tell you (all) something funny - when I first saw the pics of the plate I thought it was a spoof - because I thought you just took a nice piece of CF and crumpled up some aluminum foil to make a bed to set the plate on top of the board. didn't realize until afterwards that your mounting plates were scribbled out. Duh!

Apex Composites site shown above now appears live with announcement taking orders in late May.
Site also notes that the Apex plate fits the Hangl inserts pattern.

Just had to do a screen-shot of this awsome pic:

[Keyser Soze]

The Apex Race Plate won't work on standard 4x4 inserts. It fits inserts set up for that other plate. The one that starts with "H" and ends in "angl".

I lol'd.

Also, I like that they give Seb credit for his tent picture in the top right corner.

I like this picture better:

Look at the list of how you found the Apex Snowboard site on the Join mailing list page.

WOW! Keep it coming!

[valsam]

No titanal no carbon no elastomere no steel edges no base and alot less wood than a board so if it costs 1/5 of a board and works this should sell like crazy!
It looks like a skateboard without wheels and i think it should cost as much as one!

[Miltie]

Sean, Very cool video and explanation. Looks interesting! Keep us posted on the progress. Have fun at A-Basin!

Thanks!! Tom

The cost will be considerably less, but the volume will be nothing like skateboard production, so I'm certain it won't be that inexpensive. I think we're likely to be quite a bit less than most of the others.

[valsam]

Sean not all of us ride your boards but if your plate system doe's let's say 75% of what the other system do and cost's 75% less then be sure that most of us will buy it and you will have the sales volume that will allow the production cost to drop!

Such a thing hinges on the ability to make it fit a 4X4 hole pattern of non standard dimensions. This is a big issue. Making something like this fit around all the hardware is quite tricky. There is not a standard stance width that everyone uses across the spectrum, making it even more difficult. Weight reduction is accomplished by making parts as small as possible. Slotted parts are bigger and heavier. I'm not saying it can't be done, as I haven't even really tried, but I see significant hurdles to such a proposal.

[BobD]

Seems to me that an economic plate system that only fits Donek boards, would sell a lot more Donek boards. Nothing wrong with that.

[b0ardski]

Being able to mount to any 4x4 board would be a HUGE selling point.
I know I could really benefit from an isolation plate on my very stiff 185 carbon race that would allow natural flex & give me a bit more power over the nose.
Without 4x4 compatibility sales volume would be squat except for the racing circles were hangl or vist inserts are some semblance of common.
I understand the advantage of mounting close to the edge; but plate mounting inserts will never be a "norm" on recreational boards and I know us recreational carvers would benefit.

Thanks for sharing the developement news Sean, it's exciting to see the niche progessing with new geometries & mounting tech.

an important detail would be how much concave do you put on the base of the 4x4 mounting plate? you want it to transmit force to the edges of the board (where the custom plates mount), but not put so much force on the board that you change its longitudinal stiffness. without it being pre-stressed in some way, i think having the plate on top would lift the opposing mounting edge during a turn, limiting the area of contact over time.

agreed though, it'd be a huge seller. suddenly a whole world of binding angles would open up for me and my 31MP boots.

(see video above)

OK.... so what you said in the video seems to severely contradict the camp that believes being able to use independent foot movements to bend the board into a tighter arc or otherwise "work" the board are good things.

Your impressions of this new breed of plate, along with the acceptance and dominance of this style of plate on the World Cup and in the Olympics seems to support my belief that bending or twisting the board with your feet to some benefit is a myth.

As for your plate, looks promising! I have to wonder whether the suspension benefit will offset the weight penalty. I didn't feel like the Vist was worth it, for freecarving, but this style of plate appears to work better, mechanically. I think minimizing weight should be your second priority - the first being getting the thing to work well and reliably, of course.

[OhD]

I wonder if the cantilevered front section of the Apex plate is designed to function as a vibration absorber, reducing the amplification factor for the nose of the board over some range of frequencies. It looks awfully stiff for a reasonable mass to work as an absorber, but there may be a lot less to it than meets the eye.


I find it implausible that it functions well to keep the nose from folding - if anything it would provide a fulcrum over which to break the nose, and a profound discontinuity in the board's flexural behavior if it didn't break. I guess it might prevent a break at the binding and have some useful margin between plate-topsheet contact and nose failure, but it seems like a pretty bulky bandaid. Maybe worth the weight if that's what it takes to keep an otherwise fantastic board in one piece.

[Jack Michaud]

I don't think so. Think about it. We're going to see the emergence of a new standard insert pattern. When you buy your next board, you will choose whether you want 4x4 or Apex inserts (for lack of a better name). If you can't afford to buy a board from a company that will give you that option, you probably can't afford a plate either.

Being able to mount this to an old board you've been using for a season or three might be "nice", but if adherence to the 4x4 insert pattern increases the weight of the system, I don't think the industry should go there.

[kieran]

i'd briefly wondered if this would go as far as to change the binding insert pattern for bindings themselves, such that they'd be affixed to the board on inserts much nearer the sidewalls.
then i realised the extra weight of the binding being spread out that distance probably wouldn't make it feasible.

I think it would better callit Hangl inserts, due even Apex calls it

The one that starts with "H" and ends in "angl".

I have made the foot movement argument over and over myself. I thought I'd get on the plate I rode and immediately fall over because I was unable to pedal the board. That did not happen.

I believe I have already found about 1lb I can shed from it's mass. That's an estimation, but I see no reason I can't be down to about 5 lbs. A 184 with plate and bindings mounted to it is a beast. It's amazing what an additional 5lbs feels like when you pick up a board.

[Donek]

Unless Hangl has modified their pattern, this is not their pattern. I ran some boards with that pattern for prototyping last year. It's similar, but not the same thing. The Apex guys may have slots in their mechanism to accomodate both. I didn't look at that aspect of their design.

As far as I have seen, the diving board is basically there for the user to add bumpers at his discresstion to "modify" the flex on the front of the board. If no bumpers are used, the diving board doesn't come in contact w/ the board, unless the board is bent to a very extreme degree - and at that point it may break on it's own. The diving board is just a carbon fiber plank extension of the plate itself. Between the bindings the plate has stiffening ribs on the underside, and they do not extend to the diving board section.
