New vs. Integrity

There are so many aspects of a wakeskate that change how it rides. Its amazing how few people actually pay attention to their board when its under their feet to actually feel how every part of the board contributes to the way it rides. There is so much more to a rocker than just 3- stage or continuous and how big it is. The same goes for a board's edge. Whether its sharp or round, and where exactly on the edge it gets sharp or round. Profile is important as well, the width at the waist of the board and the tip and tails, the angle of the walls (between edge and griptape) of the board. All of this contributes to the overall ride of a board. How fast it is in the water, how deep it sits, how it edges, how it releases from the water. Getting all of the technical parts of a wakeskate dialed is progression and advancement, in my opinion far more important than materials.

A wood core is not a substitute for a wood board. once you wrap a "wood" board entirely in a composite material, it will never ride like a wood board. there is no composite board that rides just like a wood board. Its a myth. The way wood reacts in the water is unlike any other material which is why so many people ride them, regardless of the fact that water eventually destroys it.

Also, not everything that comes out of one factory is the same. I hear people constantly referring to all the wood boards manufactured by New as "News." All of these companies designed their own shapes, which when it comes down to it, is the hardest and most important aspect of making wakeskates. Most of New's clients are rider owned companies, and when you purchase a board from one of them, you're paying for all the work they put into designing, tweaking, and testing the shape they had New manufacture for them. Basically, when you buy a New, you're not getting a Remote or one of the other company's boards for cheaper because they cannot sell you one of those shapes.

i thought the remote concave shape was the same as news? im not talking rocker or anything, but concave shape at least

Mit professor explains being weightless in free fall.

http://www.youtube.com/watch?v=zfTE4J87aQQ

please correct me if im still wrong but isnt he proving that when you jump in the air you are weightless?

The "free fall" that he's talking about is when gravity is the only force acting on you. This never happens in wakeskating because you're holding onto a handle which is moving you at ~22mph. Ignoring that, you're only actually in the air 'falling' (on the way down from your jump) for about a half second at which point in time you're looking to land the trick instead of initiating it.

from wikipedia:
Examples of objects in free fall include:
An object thrown upwards or a person jumping off the ground at low speed (i.e. as long as air resistance is negligible in comparison to weight). Technically, the object or person is in free fall even when moving upwards or instantaneously at rest at the top of their motion, since the acceleration is still g downwards. However in common usage "free fall" is understood to mean downwards motion.

if you had a scale under your board and under your feet and you do an ollie from the instant you leave the water wouldnt both read zero on the way up, when you pause, and on the way down?

also how would moving on a horizontal plane affect the result on the scale?

The examples that the prof used in his video are him jumping off a 10 story building, and him jumping off a desk. After that I closed the video and typed out a post wondering why you're discussing weightlessness and free fall. Feel free to elaborate...

the only reason i posted this is in response to a couple comments from people in this thread. i was bringing up the notion that if a wakeskate doesnt weigh anything in freefall (up or down), does that make the a specifically weighted integrity any different than a board that doesnt have a weighted core. But now I realize that it's the mass distribution of the integ that's the key, not the weight.

canalskater, Thank you that was such a good explanation...

To the naked eye when you walk into a skate shop almost every single skateboard looks the same besides obvious reasons such as size. Hell half of the companies are made in the same factory right next to each other....but it all comes down to the little things as tj was saying like the shape of the rails, the width of the nose tail, and shapes of nose and tail, how mellow/steep the concave is etc

-LoGiK-, i wanna see your shop decks! i have close ties with a shop here and i was wondering if it would be worth it, and how much the boards were marked up to actually make a profit... if you don't mind me asking...

I think the biggest key physics element involved here is rotational inertia. Rotational inertia involves an objects resistance to change in rotation, this is true regardless if the object is in free fall. The closer the mass is to the axis of rotation, the less rotational inertia an object has, making it easier to rotate.

this sounds like a wakeboard discussion

i've said it once and i'll say it again, i wish integrity/mutiny would make a more traditional shaped concave deck. it would increase their market share considerably i think because some people, myself included, just can't get used to the top shape. i understand their shape is one of the things that separates them from other companies so i won't hold my breath, but i can dream.

mank the tank, I ride for Arson Wakeskates, I support them 100%, and I really enjoy riding their boards.

I don't know Soy, but I know he has a lot of passion for Integrity and I really respect him for it. One of the statements he made bothered me because it seemed a bit unrealistic to someone who has ridden an Integrity for more than one set, as well as the other board in this thread, so I said my piece. I always enjoy watching him ride and I have a huge amount of respect for Integrity, don't get me wrong.

When I joined this site before I could do a shuv-it, one of the first videos that blew me away was Ryan's flats v-flip in the trick tips section. Ryan has been on a wakeskate for many years more than I have, so my opinion doesn't have nearly as much experience behind it. My opinion stands, but one day it very well may change.

I'm happy someone wanted to question this... It's actually made me pull all my old info together and realize i never properly marketed or explained the reason for the Cenrta-Fuse core.

"Angular Momentum" "It's science"!!! sorry to all the critics, but it was intend to do exactly what it does... it's NOT a gimmick!!!
It is PHYSICS ... look at figure skaters and how a spinning top works.
here is why we developed it...
and why it is shaped like a dog bone.

centra-fuse core has a 6" center mass where 75% of all the boards weight is located (low moment of inertia). your wood boards has most of it's mass out on the outside of the mid waist at approximately 15.5" wide.(high moment of inertia requiring more torque force to execute) so Integrity's axis is 6" NOT 15.5" by having the majority of the weight in it's center axis you have a balanced instrument that spins truer with less torque to move it.

here is a cut and paste of:

"Conservation of Angular Momentum"

The key is applying the physics principle of the conservation of angular momentum. Physicists measure the amount of spinning motion using angular momentum. The amount of angular momentum that a spinning object has is related to how fast it is spinning, how massive it is, and how far the mass is from the axis of rotation.

If something is spinning rapidly, it has a greater angular velocity. Physicists use the moment of inertia as the rotational analogy to mass. The moment of inertia is determined by the mass and distance the mass is from the axis of rotation. Increasing either the mass or the distance that all or part of the mass is from the rotational axis will increase the moment of inertia.

The definition of angular momentum is analogous to the definition of momentum. Physicists define momentum as the mass multiplied by the velocity, so physicists define angular momentum as the moment of inertia multiplied by the angular velocity.

The law of conservation of momentum states that the momentum of an isolated system, with no external forces, is conserved. Analogously the law of conservation of angular momentum states that the angular momentum of an isolated system, with no external torques, will always be conserved.

Figure Skating Spins and Angular Momentum

The more rapidly a figure skater is spinning, the greater her angular velocity.

The figure skater can also adjust her moment of inertia by controlling how close her mass is to her axis of rotation. By extending her arms and one leg, a figure skater can increase her moment of inertia. By pulling her arms and legs close to her body, she can decrease her moment of inertia.

The figure skater's angular momentum must remain constant according to the law of conservation of angular momentum. As she changes her moment of inertia, her angular velocity must also change so that her angular momentum remains constant.

If a figure skater starts spinning slowly with her arms and possibly one leg extended, she initially has a high moment of inertia and a low angular velocity. If she pulls her arms and leg in closer to her rotational axis, her moment of inertia decreases. Her angular velocity (spinning speed) must therefore increase to keep her angular momentum constant.

When a figure skater wants to slow her spin, she can simply extend her arms again. Her moment of inertia increases, and her angular velocity correspondingly decreases. The figure skater's angular momentum remains constant until she applies an external torque from the ice.

When performing jumps combined with spins, figure skaters need to land pointing in a specific direction. For example a figure skater might want to land so that she is facing and skating forward after landing. By making slight adjustments in her arms a figure skater can fine tune her moment of inertia, which will in turn fine tune the figure skater's angular velocity. The figure skater can therefore precisely adjust the number of turns she will make during the jump.

Even if they don't precisely understand the physics involved, figure skaters use the law of conservation of angular momentum to gracefully control their spins and jumps.

i've always thought the centrafuse core explanation was pretty good, and the old limiteds that let you see it really helped also. it's a similar concept that hyperlite and byerly use "weighting systems" in some of their skates.
