Aaron Kyro - แนวปฏิบัติและการใช้ชีวิต
i ollied onto a 10cm curb today and that doesnt sound like much but its quite an accomplishment for me since i have a problem with commiting to my tricks
nice man
Good job :)
Congrats! I had the same problem, but once you start, it starts getting easier. Keep skating!
Good job man I remember how important it was to me keep progressing man
Ah i remember when i learned that. Feels awesome practice that a lot and then you can just cruise and olie onto curbs.

Anyone else watched this after ruining their tail and going “shiiiiii” 😂😂💀
I when I was a beginner I scraped my tail now I know it ruins it
@@Will-km1nv same bruh and now I got razor tail and my board chipped 😔
If that's razor tail, then what's my board? Scalpel tail?
+Caleb Brown haha xD
+Caleb Brown LMAO! 😄
Same thing happened to my board😂
What's so bad about a razor tail I don't know anything about that
+Joey Kham Literally the whole video explains just one of the problems. There are also things like it chips easier and stuff.
It's true that the older board has more surface area during the pop, so the force is distributed over a greater area, meaning a higher pressure on the ground. Still though, the same amount of force is applied with the foot. Every action has an equal and opposite reaction: the upward force (from the ground) is _the same_ and the area doesn't matter.
I would think the true reason for the reduction in pop is actually related to the structural integrity of the board. When the board is used (over a month or several) the board will flex and bend through riding, tricks and boardslides. This will cause microfractures in the board, it will loosen the glue between the layers and will basically make the board less rigid.
What _really_ happens is that the energy from the upward pop force is lost through the deflection of the board. With a rigid new board, when you ollie _all_ of that upward pop is transferred into movement, into the ollie. But with an older flexible board _more_ of that energy is lost in making the board flex.
Think of it this way: suppose you have a rock and a sock full of sand, equal in weight. The rock (totally rigid) will pop off a wall or the ground if you bounce it. The sock-of-sand will simply thud into the surface and won't bounce much because it's more flexible: most of the energy from the impact will be distributed internally through the warping of the object.
Edit: Similarly, if you have a beach ball and you smack it with either a frying pan or a chopstick: if you hit it with the _same force_ it will move the same distance at the same speed, even though the chopstick will contact with much less surface area. The pressure (force over area) isn't a factor in these rigid body collisions.
That's exactly what I thought too, how would a slight amount more of surface area touching the ground reduce the force on the ground?
+Henry Gordon
Yup, it all comes down to the degradation of the board material. With a new board you get a nice springy elastic collision with the ground (and more bounce) whereas with an old board much of the pop or rebound collision energy is lost through permanent deflections and cracking/micro fractures in the deck.
very true and nice analogies
+Torgo it doesnt reduce the force, but as aaron said it is because it is spread over a bigger area. but also it might actually just reduce the force, because of the difference in angles? i dont know, but i believe if a brand new board with no cracks or microfractures in the deck, but constructed with a razor tail it would pop less than a regular brand new one
+Jens Petter Lund
There is no difference in angles; the foot pops in the same direction regardless of the shape of the tail.
What a shame I'm wasting all my pops on funcking up ollies
Beginer struggles
my board is so worn i could shave my back with it
Same
Its my concealed weapon
i literally read this comment and then i got a shaving ad
Same lmao
Well, I shaved my leg with with my razor tail yesterday while ollieing off a stairs
I watched this during school thinking I was slacking off, but no Aaron comes through with a very informative lesson. #Surfacearea
Samuel Fisher ikr it is easier to remember
It sucks to live over here in England because 1) the rain ruins your board and loses pop and 2) it recks the bearings and my wheels make a weird sound when it rolls and it doesn't spin as much
Dont skate in the rain?
Liam McGhie
When living in England, that is impossible.
Forreng Exactly
Liam McGhie it rains 370 days of the year.
Couldn't agree more. Had to say goodbye to some amazing bearings that lasted years the other month. Right in the feels
I have terrible razor tail and i don't wanna buy a new deck dammit :(
Damn Aaron could be my new science teacher :D
Haha! I would love that!!😜
***** Aaron is better than my science teacher he explains things that actually makes sense
he did study in science or something like that
Just the video that I need cuz I was so confused as to why my ollies are getting lower and lower everytime. Thanks aaron and your awesome!!
It's important to mention leverage too. There's a principle that the more you expose something to frictional resistance the more the thing will mould to be able to handle that resistance with more control. For example, if I roll a wooden dice a million times, eventually it will stop "popping" of the ground and start rolling - it will become a sphere. In the same way, if I scrape the tail of my board along the ground a million times, eventually it will form a flat surface that "controls" the board better, so it will bounce off the ground less.
I have noticed once you scuff down to the coloured layer in the middle (4th from top or bottom) that the pop is basically none and takes so much effort
Another thing that effects it is that the board becomes less rigid over time (microcracks form that allow it to flex more).
The science is, MONEY! manufacturers want your cold hard cash!
that's revives m.o.. get a Santa Cruz deck and a tail bone
JAyy781 lol no. They can't make wood last forever.
@@crimson1718 so buy blanks, they cost like 20-30 bucks
OMG! This helped so much! Thanks Aaron
How much did you get paid by force wheels for saying "force" at 1:24 ?
One billion dollars (in a dr evil voice)
well im pretty sure hes sponsored by them and gets clothes, wheels, revive decks, stickers and possibly oversized ricecrispy treats for free so he just does it out of the caring love in his heart.
Force is actually just the correct word to use for what he is trying to explain
TrkJustin can you not see sarcasm ^
TrkJustin its people like you that make me look in the mirror everyday and say, "thank god im not an idiot"
I had a blind board for about 8 months and it got bad razor tail but I was still able to pop high and do a lot of my tricks high but I got a new board and I can feel the difference from my old one to my new but you just have to try harder on an older board which is a fun challenge.
Makes sense to me. Back in the day, (that would be the 80's), I had a Santa Cruz Spidey deck and my buddy had a Santa Cruz something-or-other (forget the name), but it had a tri-tail, where the sides where bent up and it was like a point at the end, and I could ollie that board way higher than mine, never really understood why until now.
Love that intro.
Nice job, the old days when aaron was doing every video 😎👍😊👏 man he has grown this company, love braille.
Dude in my opinion you'r the best skateboarder i ever saw.
I think the angle at wich you have to pop your back tail as it wears would be a bigger factor than the effective surface hitting the ground.
Another thing you can try is sanding the nose/tail down where it has worn away, yes in turn it can shorten the board so I advise you not to do it on newish boards. I have done this myself to stop it prone to chipping too.
Can any one help me on how to post a TH-cam video
jaidev avalos you should not be on the internet lol, fs
Hey Aaron! How long have you been skating? Because you are great at it.
Step 1: sand tail/nose down with 60 grit sandpaper to proper shape.
Step 2: skate more.
Step 3: save money
Yeah, it's gonna make the tail shorter, but it will extend the life of the board by a few months.
more like ruin the skateboard and you say it will EXTEND the life of the board? not even close it will do the exact oposite. who the hell can skate a deck with almost an inch shaved off the tail? it just doesnt work bud.
north seven o five It does work "bud."
I said sanding, not shaving. there's a pretty big difference. There are also a ton of board shapes that have shorter tails. Look at some of the Welcome boards for a better visual.
I've done it to 3 boards, Anti-hero, Real, and Girl. The Anti-hero lasted about 9 months, the Real board lasted about a year until I intentionally focused it, which resulted in me having bent bolts/trucks because it wouldn't break and the Girl board lasted about 5.
I don't know what gives you the idea that it's not possible. it's more than possible.
north seven o five You're not sanding it down unless it has already lost it's life anyway. It's not like you are unwrapping it an immediately shortening the tail.
lol 60 grit? That's coarse af....1200 grit for sure. I used to use that grit to sand concrete...
Learn Something New Yeah, it is coarse, I recommend doing it by hand and it doesn''t matter how rough the sandpaper is, the board is still going to be smooth, maybe not as smooth as 1200 which is a bit ridiculous to use on wood unless you're getting rid of the graphic and want to smooth it out and 120 should be good enough for smoothing it out anyway. It's wood, not concrete. You're just going to have your board drag around on the ground and hit things when you're riding anyway (because everyone messes up now and then).
I feel like you guys don't even skate (meaning you lack actual experience with working on skatevoards) and just want to ridicule someone's idea. I've actually worked on boards for as long as i've been skating, so experience outweighs online ego in this situation. Not saying you have an ego problem, it's just dumb to comment about something you haven't done or know nothing about.
Thanks that helps so much you r the best
I like how you advertised the board when u said”as much pop as Braille boards”
I've skated with a few people that have crazy pop on raggedy boards. I remember this one kid martin..he was poor and couldn't afford new stuff but he had good technique or something because even his switch tricks were popped up high.
love how you randomly switched accents in the beginning
Basically more of the force you use to pop the board is lost because the surfaces hitting each other are big. Smaller surface contact means less force is lost so you get more pop.
hey aaron i would be interested in your opinion about the differences in skating low trucks vs standard trucks, there's hope to see a video about that in the near future?
I feel so dumb.. I’ve been practicing the Ollie for 2 weeks now and I finally figured out why I can’t do it...🤦♂️
Same i was doing the same motions and getting air but even as hard as I stomped my foot it never got high
@@rain2day1 same, i could pop on my homies board like it was nobodies business, yet on my board, i barely pop
same with me but for a whole month
Nah man y'all are making excuses trying to scapegoat. Norma Razor tail will not prevent you from doing an Ollie, it just impacts the height of it.
The issue is the fact you are learning the Ollie so it is your technique.
I have a Board with mad razor tail and can still Ollie over two skateboards stacked.
Don't lie to y'all's self and blame razor tail when it could be your technique
Could u do a video on the difference between riser pads and high trucks? Thanks
Aaron is actually correct in what he is saying. It has to do with two basic principals of physics, impulse and pressure. Pressure being the amount of force per unit area. If the same amount of force is applied to a lesser amount of surface area as a larger amount of surface area, the amount of pressure is going to be greater with the smaller surface area. Pressure is P=F/A. Impulse is the product of a force and the time in which it acts. In this instance if the surface area is larger the pressure will be less because the force is being defused across a greater surface area. This leaves us with less force and thus the board will not accelerate as fast. So a greater amount of force must be input for the same amount of force output.
How often should I replace my board ?
every 45 minutes if your skating hard
If it has chips or razor tail or just feels sloppy its time for a new deck
na every 45 mins bro trust me i can kickflip
Every year or if it snaps!
Michael Evans Every year? I'm in need of a new deck every 1-3 months, it depends how much you're skating really
great advice
Although the back of the board wears away, a smaller tail can give an ollie a larger angle when popped so that you can ollie almost straight up... if we are talking scientifically
Aaron, the area which the force is distributed over does not affect the total force applied. For instance, 2 square inches of
.5 lbs per square inch will be an equal force to 1lb per square inch over 1 square inch.
Because A=f/m, the acceleration will be equal for both surface areas, and therefore surface area is not a factor in board 'pop'. This being said, it is true boards do tend to lose pop when they are razortailed. I don't know why this is, but I wont pretend to know either.
Thanks Aaron
Went to buy one of your decks Aaron, but there aren't any in 8" available, is there another bunch being made or do I have to suck it up and go bigger?
Ohhh that makes sense now
I can't get off the ground good when I Ollie any ideas how to get more air or do a better Ollie or Ollie in General
Can u do a review on square or rounded wheels.
So do you guys think if the board is more scraped up on one side of the tail that it will pop at an angle and not stay straight?
My friend has been skating his creature board for 2 years and he skates big transition he is just now starting to get pressure cracks down the center from nose to tail inbetween the bolts
lol I could barely afford a new deck lol
Fuck me I hate when people say lol twice in the same sentence
+Ayden Chapple lol
+Rafael Playz -_-
Same... I get $20 a month. Thats like 5 months or something if i get new stuff minus bearings and trucks.
TrickShot Gamer $20 a month? quit the job you have immediate bro
What deck/brand has the most pop cause I'm looking for a new board. Thanks
That makes sense. Mine is ground to the top ply.
I think if you were to follow this same logic, it would imply that you would jump higher in a pair of high heel shoes as apposed to flat shoes because the PSI increases when loaded up onto a small point on the shoe. This isn’t the case, though, because if it were you would see people setting record-height jumps in a pair of custom shoes that came to a small point at the ball of the foot.
Hey Arron are you doing any skate supports right now?
Aaron could you do a Nollie Bigspin Trick Tutorial??
Can you do a board with razor tail and sculpt wood filler on the razor tail and see if that would restore pop?
good job man
Nice my son loves skateboarding
That was the best intro ever.
I leave my boards in a small room where a tumblr dryer is on constantly. Could the heat from the tumble dryer dampen the pop in any way?
I refuse to think about science when I'm not in school.
Does anyone know where you can get those things that you put on the tail so you dont get razor tail and if so what are they called
exactly what role does concave play into pop in the board?
In addition to the razortail, doesn't the whole tail just become more flexible over time? I've noticed mine is kinda squishy, but I'm also 180 lbs...
This has been physics 101 with Aaron Kyro
help me please with this problem i push goofy but do tricks regeular and thats a real problem for me
Is there anything I can put on the tail to prevent it??
When is the winner going to be announced for the weirdest trick contest?
my board is thinner then everyone elses and i use to always use my tail to stop me and now its really hard to ollie should i just get a new board?
i've been skating for about a month and i have the worst bloody razortail in the world idk what do to beacause im scared that it will break any tips for my razor tail help pls
Thanks yeps Aaron
thanks for that imfomation
hello, my name is Aron kyro and im a professional skateboarder from the San Francisco bay area and today im going to teach you how to kick flip.
For the first like 16 or 17 seconds, Aaron's accent was awesome
It has more to do with an old board absorbing your force because it is soggy or flexy. Where as a new board just transfers that force to the ground
so can smaller boards pop higher than larger boards ?
what bearings do u have and what trucks do u have
He is so great at skate
Is the pop difference significant? I'm thinking of buying a used board
what makes ReVive decks better than other brands? who makes your boards?
that makes total sense I have half of my tail left now because of all of my tail stops and now my board is pretty much unusable
Yo Kyro. Wood (material) fatigue. Happens with wooden bows. Probably happens with skateboards too. I wanna see your video on that.
Awesome!
will there be no skate supports anymore?
What if you buy a brand new board and never use it? Will it still keep it's pop after, say a year?
I need help I got a new board but got stuck in the rain for the first time and I’m afraid if my bord is warter logged
When is the next Lance video coming?
I'll be honest, I skate Revive boards and my last got beat DOWN! Rain skated, wore the tail down through the middle ply, but I never noticed a loss of pop. I just got board of that deck which is why I setup a new one, not because it lost any perceivable amount of pop.
I love dgk boards they always have good pop but I just got a brand new one and it sucks ?? Anyone can explain ??
if you get tail sheald you pop always good?
what are you guys opinons on chocolate boards because i feel like my became a peice of shit after a 2-3 mabey 4 for id dont know bc i got grounded for like half a year but once i got back on it there was literaly no pop left and i could do shit
Arron “Where going to go into the exact science”
Also Arron “actually wears away less fast”
After quiet a bit of years I found the decks that works best for me are Chocolate(for the shape) and one thing they hardly loose is the pop, been having tons of them and they just stay almost as brand new!
I never owned a chocolate deck but mystery also doesn't loose that much pop either but they kinda chip easy also creature pretty good
E WALL can't find Creature here but I tried both Zero and Mistery when they were a thing and New Blood was going strong. Well, both the brands didn't work well, they snapped and chipped way before I could even consider it was time for them to loose pop...I know I'm doing more technical stuff now but Chocolate lasts me really a lot and they always crack before the pop is even starting to go away...and breaking them takes me a while :)
I'm not changing deck since I've been running them for years now and never disappoint, one thing I changed this season tho was my shoes from Vans to the hard rubber Janoski's, that's another world and landing primo doesn't hurt anymore. It may seem a little but they help me pop even more and land even more technical stuff, I think I finally found my perfect combo :)
+AndreCorner chocolates are nice,i have one right now actually.i like them enjoi and deathwish
Jonathan Kosyjana tried Enjoi but that was a friend's 7,5" which is small for me and couldn't properly test, never saw Deathwish here tho!
the best smoke in the bay !
Nice video! But Aaron could you maybe awnser to this video because when i do my bs180 i practice now for i think 1-2 months and i still can't land it, i think the problem is that my shoulders are not really turning the way it should be and i can't get used to it, i really want to step over to another trick to the frontside shuv because i can do a pop shuv already while riding but the problem is i can't do it all the time, like 4 of the 7 days i can land it and i can it like 10 times in a row, sometimes it feels like i never going to get it down, pleas reply Aaron it would mean alot
just do that one trick while rolling around over and over until you get it consecutively. It's practice. or just find someone who can do it and copy them until you get it.
I personally learn faster when I have someone to skate with.
i can ollie over 24 inches (3 decks) with my 6 year-old board.
I used to ride in rains or even washed with water.
(I was too young to have idea of water ruins board. lol )
i think it is just an excuse saying "my board has no pop :'("
no u suck
Jonathan Bartholme Don't be hatin'.
I'dd lov to buy this old school Revive board :/
Wait so what about P2 boards? They get pretty worn out to but still hold Pop a little longer
I rode my board in the rain and noticed a significant loss in pop. was it the rain or something else?
I don't know how old you guys are, but this is kind of common sense
Aaron, Do you think you could do a video on why a lot of goofy people learn heelflips first? Thank you
