Bro I really appreciate your video. I'm just getting into skating. It helps knowing how the designs work. I had know idea how much math, trig, phys, went into this. Appreciate it,
I recently needed to make a 3d model of a skateboard and I didn't really understand what I was looking at when it was time to make the trucks, this video was incredibly helpful
You guys are real gems. I didn't even know about the other trucks besides king pins and didn't even know what made Rkp different. I wonder if you guys would classify avenue suspension trucks as tkp or something else. Your videos are helping advance my skate level. If your in anchorage you guys should hit me up for some frozen street luge with the safest skater in the city
this is great stuff, it's line going to college. important question. can a skateboard steer if the back truck is really stiff but the front one is not.
Im replacing my powerwheels front wheels with 14" or so section of skis (possibly snowboard). I want them to slightly roll (or cant) as they yaw as steering wheel is turned, so the edges are more effectively used. Also to prevent edge catching/catastrophic failure. Skateboard trucks upside down seem like its the answer but im not sure. I think this vid is helpful but since its a different application, i can't tell. Anyone understand what im looking for?
IMO, usually any quality name brand truck will work. The biggest factor which is easiest to change is going for quality bushings. For instance, I bought a used board with stock trucks and bushings in it. I could take it to about 25 before it would start wanting to get all sketchy on me. I upgraded the bushings to some nice ones from Riptide, went way softer than the stock bushings I had before, but despite that the board is still way more stable. I can lean for days, but still feel more stable going 30 than the board used to feel at 22.
Hi, I have a strange question, have you guys ever tried your trucks with a deep drop longboard deck? (as in like a 1"-2" drop) And if you have, how does it feel and how does it react? Im also wondering if you guys have ever tried tandem axles. I wonder what would happen if you used tandem axles on both the front and back trucks. Would you get a ridiculous amount of grip in corners? Would it speed wobble easily? I dont know, but i was hoping you guys could make a video about it. Thanks!
We have. 1" is pretty much pushing it. They're low already, so a 1" drop on OPs is equivalent to more like a 1.5" drop on some other trucks, Plus with the cam and the rising center of gravity it starts feeling like you have to put Way too much in just to get the board to lean. 1/2" or less tends to be about right for the dropped deck feeling. We haven't tried tandem axles, but we've thought about it. You see them somewhat frequently in luge, I'm not sure its so straightforward as if you use them you get more grip, otherwise you'd see them a lot more. For speed wobbles, I think the consensus is that it can help. I think the theory is that they cause interference with each other, and cancel out a lot of resonant energy.
hmm, interesting. Thanks for the reply, ill keep that in mind. Id be interested to know how the tandem axles, whether front and back or front only, affect grip and performance, and which is more effective.
How do I determine what type of truck I have? I lean left and the board wants to go right. My kingpin bolts , pivot cup ? Bushings,. I don't know what type I have
That sounds like you have backwards trucks. On RKPs you have the bushing in the middle between the axle and the pivot cup, and on TKPs you have the axle in the middle between the pivot cup and bushings. On RKPs you mount the trucks with the bushing/kingpin facing outward toward the nose and tail, and on TKPs you mount them with the bushings facing inward.
Apparently, from what I see, this video actually explains the origins of speed wobbles very well too!!!! Can you explain the behavioral difference between bent-pivot and straight-pivot TKP's, please. (Preferably in the perspective of grip, slip, turning, leaning, etc. for sliding)
Ok, I know about a lot of these trucks, but what still puzzles me, is "What is the effect of Rake on your ride?.. i have a "Vert-Deck" with independent trucks which have a low angle, and also a vintage model deck with Bennet Vectors, which are quite steeply angled, and have a lot of rake.. i know they turn very tight, but is that from the angle, or the rake?
Angle is probably the major reason why. Rake won't make it turn any more per degree of lean, but it can change the way the bushings are engaged making them act a little softer, kinda like how adding a risers makes boards more turny.
I believe ‘rake’ on a skateboard truck has the exact same effect it has on a bicycle front wheel. If I have to venture a guess it determines the degree to which a truck wants to stay into its straight facing alignment (or not turn). More rake represents a truck that wants to roll straight forward ‘more’ than a truck with less rake and needs more force put into the lean to make it turn... despite the angle of the kingpin which only influences how much it will turn for a given angle of lean (as is the case with a bicycle steering wheel) the rake determines how much force is needed to create that lean. This is dependant on and influenced by the weight of the rider as it is what causes the rake to have the straightening effect on the ride. At the same time more weight causes more force applied during lean so the effects sort of counterballance each other. This is all a guesstimate from my part though :-)
No rake = more stable for faster runs. with rake = the truck is more likely to turn, so a bit unstable. it´s more a question of how you personally like it.
That's not accurate. Forward rake makes a truck less stable because there's negative trail. Backward rake makes it more stable. 0 rake actually gives a negative trail for the front truck because the wheels are not dimensionless.
Bro I would really appreciate if you were a member on my fb group Skateboarding and Longboarding Science and Technique,your knowledge would be really usefull. Congrats for your channel,keep it up the good work.
seriously though. i know there are some hills i could break the land speed record with a better setup. they been using the same technology since the 8 track tape
So if i were to mount an engine somehow to a skateboard and chain to a wheel does that mean the skateboard would lose steering functionality or the chain would come off
very clear, you should analize the cx trucks from carver or any other copy which are an example of RKP with a pivot angle of almost 90 degree, they are probably the most turny trucks on the market using just a simple bushing. I tried my self to made a super turny board playing with TKP, angled risers and a short board (I cut a skate) ua-cam.com/video/q6HJmX83hiI/v-deo.html there is lot of italian talking in the video, but you can fastfoward. result is that is very agile, now I painted it and is my best board to move in the city. however it is super turny, is not as much as a cx truck. I understand that as much as I can angle the riser a TKP would keep having the bushing displaced compared with a cx and that should some how make a borderline. I tried a few times the cx, but I don't have one to mess with it, this shit is expensive :)
yo. have u seen the 128 mph rc car video? check it out. u need to design me some trucks or a back truck that can handle motorcycle speed. u build it i'll skate it.
Please don’t make any more videos. That was confusing af and when you display the props you wave them in the air for a quick second and your hand covers the whole prop so none of the trucks you show in your video are visible.
he looks Like Shaggy
Jason Brody loool
Mhm
Shaggy gets bitches, do you?
i really love your dedication in explaining... god bless you brother... rise and shine!
This guy looks like the thypical dude who absolutely doesn't look like he skate but actually is amazingly good

You're going to make an amazing teacher one day.

Skateboard trucks:
and I would've gotten away with it, if it weren't for you medallion scientists!
Suuuuper helpful. Thank you so much!!
Well there was no need of pen-paper, coz u explained very well with your experiment setup. It was clear by your practical explanation. 😊
At 4m1s you're mistaken. Lean/turn is never a linear function, for any pivot angle. Otherwise, great video.
True, it is a useful way to visualize it though.
Thanks for responding guys and for acknowledging. Awesome work, very interesting channel.
This video kills! So awesome!
Thank you very much for an extremely informative video.
Great explanation bro...thank you very much!
Thanks for this. It made 0 sense until now!
would be interesting to see update of the video with all the different surfskate trucks
Dude... that was impressive.
this is great stuff, it's line going to college. important question. can a skateboard steer if the back truck is really stiff but the front one is not.
Great explanation
Isn't an RKP truck just a TKP truck mounted "backwards" (180 degrees off) on the board? If not, why not?
Why won't the two trucks conflict?
For example:
If you leaned right, the front truck would turn right, but won't the back truck turn left?
Im replacing my powerwheels front wheels with 14" or so section of skis (possibly snowboard). I want them to slightly roll (or cant) as they yaw as steering wheel is turned, so the edges are more effectively used. Also to prevent edge catching/catastrophic failure. Skateboard trucks upside down seem like its the answer but im not sure. I think this vid is helpful but since its a different application, i can't tell. Anyone understand what im looking for?
What type of truck would you use with high speed application? To stop the death wobble that occurs!
IMO, usually any quality name brand truck will work.
The biggest factor which is easiest to change is going for quality bushings.
For instance, I bought a used board with stock trucks and bushings in it. I could take it to about 25 before it would start wanting to get all sketchy on me.

@@LongboardTechnology Thank you!
that was very educational. thx a lot.
Perfect!!

I'm wondering why people would not want an offset axel. Is it more prone to breaking on impact or is it less stable than trucks with no raking?
No rake = more stable for faster runs.

That's not accurate. Forward rake makes a truck less stable because there's negative trail. Backward rake makes it more stable. 0 rake actually gives a negative trail for the front truck because the wheels are not dimensionless.

well mine dosent want to TURN WTF
I don't get your drawings. Is it a top view, side view, rear view?
His drawings are from a side view, to give a view of each I,important factor of the truck
the first example is wrong. you are mounting the ''wood hanger'' reversely. I mean the angle that between hanger and deck plane.
keep at it. u are on a good parh
thnks
seriously though. i know there are some hills i could break the land speed record with a better setup. they been using the same technology since the 8 track tape
So if i were to mount an engine somehow to a skateboard and chain to a wheel does that mean the skateboard would lose steering functionality or the chain would come off
nice vid
I didn't know Shaggy skated???
not really the kind of truck I usually have in mind, but okay

I did have a quick look at them is this video: ua-cam.com/video/gwPx8T-4xb8/v-deo.html
They're pretty interesting.
Nice & Thanks :)

Where the fuck is scoobido 🥺
Lost me at the drawings... Should've shown what corresponds on the actual truck.
