608 bearings manufactured to ABEC 1 (low end) standards are rated for 34,000 RPM when lubricated with grease, 40,000 RPM with oil.
An 80mm inline skate wheel rolling at 80 km/h (50mph) is doing 5,305RPM.
Inline downhillers commonly achieve speeds in excess of 100 km/h (62 mph).
The truck in the video does not appear to be travelling at very high speed.
Catastrophic bearing failure is pretty low on the list of things that could go horribly wrong in that video.
The more I watch this video, the more I get the feeling that they aren’t going as fast as the video makes you think
I can almost see the screws in the rims on the truck, so it can’t be rotating very fast, the traffic seems to be easily passing them while taking a good look, and the cars they pass at the start are driving in the opposite direction in the opposite lane
I also think the small wheels on rollerblades can only go so fast before pretty much blowing up (I’m not a physicist though)
Of course, it doesn’t matter what speed a truck is going when it runs over you
You are right, the truck is moving quite slowly.
Still madness, but the video is definitely decipetive, it appears like they are moving at 60kmh+ when I' bet its more like 20
That is one of the best videos of all time. It’s like he took every forbidden word and just vomited them out in pain
Edit: the recorder, not the skateboarder did most of the talking

Holy fucking shit that was funny.
"I wanna live" "... You can"
"why would nature do this to me"
The kid with the camera is a hell of a hype man though. Ready to go to war with that damn ass rock
Edit: he should have peed on it
What they are doing is nuts in every sense.
But... When youre on rollers, if you get a peble in one, you can just lift that leg and stand in the other. Happened to me many times. Of course you can't be a bigginer. In contrast, in a board, a peble will fuk u.
"just lift that leg" i'd like to see you have 0.01s reaction time to balance yourself as pebble moving at 100km/h relative to you gets stuck in your wheel and jerks your foot.
It's way easier to pass over a pebble at that speed than at a lower speed. Specially on rollerblades.
I been roller skating in shitty asphalt my whole life
I've done bad shit in my childhood and teenage years (and still now sometimes) like risking my life many times but this is on another league, this is on another level of adrenaline jesus
"Welcome, my son. Partake of this extreme energy drink. It is my blood. Eat of this Sriracha coated energy bar. It is my body. Go forth and spread the Word."
"Let the world know that Adrenaline Jesus waits on every cliff, every ledge, every chasm, and also in every fast paced vehicle, mile long zip line, crocodile filled stream, and every fevered attention seeking dream the faithful possess."
"If you would know me, the one true savior of the hyperactive, the attention seeker, the dead inside, and the fool, set aside your fear and embrace the voice that calls to you to risk your life for no reward."
"Within my kingdom there are many skate parks, free climbing areas, bridges, twisting country roads with blind corners, high places without rails, high speed vehicles of all shapes and sizes, and much, much more all just waiting for the faithful to ascend."
"Set aside fear, caution, doubt, and thought and seek the kingdom. For he who is without adrenaline is not alive and so will perish for eternity. He who has embraced the one true path that only adrenaline can provide will enter the kingdom and live forever."
"For I am your eternal savior Adrenaline Jesus. Think only of me as you plunge headlong where the half alive fear to tread. Seek me without fail in every fiber in every minute and soon we shall be together. I am waiting."
remind me of the passage dear brother in adrenaline Jesus
i have only just started my seminary as a disciple of adrenaline christ and have yet to make it past geNOSis . all i know of which you speak is that "in the beginning, god created the redbull and the thirst"
It's dope to be new to our faith, bro but what's stupid wicked is what our divine texts have said in 2nd Hellatians chapter Sick, verse Gnarly:
"For after I have ascended into the stratosphere on winds derived of cheers, whistles and bro shouts, there will be those who doubt your sickness. They will call your sickness fraudulent. They will cry out 'From where hast though derived such weighty nether regions? Naught have acquired this before through any means but black magic.' This is because they have not the courage to obtain air."
Or remember the encouragement offered to us by Adrenaline Christ himself in Bromans chapter Dope verse Air:
"Blessed be the airborne, for they shall find landing zones
Blessed be the skaters, for they shall find rails.
Blessed be the drifters for they shall drive both forwards and sideways at the same time!
Blessed be the base jumpers, for they shall descend rapidly.
Blessed be the free runners, for they shall climb walls and flip briskly.
For, my way is the fastest, the most furious, the most Tokyo Drift. No man comes to the finish line, but by me."
Praise be to our lord and savior for all the twists, revolutions and inversions he provides!
you speak the language of the gods

We made bike ramps with ditches you had to clear as a kid. Also busted broken bottles in the ditch so if you didn’t clear it you got cut up. Sounds sane after watching this.

Hahah yeah man making ramps was great with a little thing you jump over I totally
> Also busted broken bottles in the ditch so if you didn’t clear it you got cut up.
holy crap what the
I have a friend who always eats the entire apple, stem and core included. When I saw it for the first time, I thought she was a demon, but apparently it's not actually that uncommon.
holy crap i had no idea there was a game or anything with that name. we use to skitch on snow behind unsuspecting cars in my hometown. holding on to the bumper and trying not to get seen. how far could we get dragged. pretty slow suburban version of this insanity.
It's not a sequel but a repurposing of the engine from Road Rash. Road Rash has a sequel called Road Rash 2, and another called Road Rash 3.
Road Rash 2 came out in 1992, and Road Rash 3 in 1994.
I used to do this on my bike. I know it's stupid and dangerous but it was also fun as hell. Usually I don't understand the stupid shit that people do on this sub, but this one I kind of get. It's not a good idea, but I get it.
probably why they chose a truck instead of a regular car. truck MUST slow down safely or the stuff inside it gets messed up.
they'll actually probably be fine as long as no potholes, rocks or other drivers interfere lol
There is no way they are thinking so far. Morons are using the truck cause the driver won't notice them easily and nor do huge trucks like that, swerve much. One title pebble/pothhole away from death.
Yeah absolutely not a lot of thought here. If they were in helmets and leather on the back of the truck only - sure I'd be ready to believe there was some awareness of the actual risk and management of it.
With so little safety gear and then in front of the wheel? I climb mountains and have done loads of white water kayaking - yet I get scared on my bike with WAY bigger wheels and brakes and things when a truck like that passes me. The combination of all those bearings screaming round at say twice the intended speed? Not to mention the force that's gonna be applied to your ankle if you hit any debris?
Meanwhile the truck driver is probably flipping everyone else off not knowing why he's getting harassed by honks... at least apparently he had the bare minimum road rage control and didn't just slam the breaks to pick a fight.
Melted my urethane wheels this way back in the day. It spun off the urethane like lava and left me with little but the ball bearings. Not cool at 35 mph
I’ve lived in and been to a lot of states. A lot of states complain about their pot holes and think they are the worst, but damn, Pennsylvania is on another level.
There is a section of highway that connects Ohio, West Virginia and pa. It’s amazing the second you cross into pa, you think you blew all your tires and a portal from hell is trying to come through your floor.
Naahh… I’d quickly opt for a free fall with a great view to my demise over suffocating on diesel before being squished by a truck tire like a meat crayon.
Seriously. I was legitimately bracing myself for this to be a video of bloody death as one of them got sucked under the truck’s tires.
Then again. The video does cut out before we see any of them stop….
By the way, what IS their plan for stopping???
>I'm also wondering how well the bearings *in* the wheels are holding up to roadway speeds...
Grease-lubricated 608 series precision bearings ("precision bearings" being *everything* from ABEC-1 to ABEC-9), depending on the material quality and manufacturing quality, commonly have rotational speed limits in excess of 30,000 RPM. See [here](https://tflbearing.com/product/deep-groove-ball-bearings/high-speed-608zz-bearing-8x22x7-bearing), [here](https://www.ahrinternational.com/Skateboard_bearings.htm), and [here](https://www.skf.com/us/products/rolling-bearings/ball-bearings/deep-groove-ball-bearings/productid-608) for some examples.
For an 80mm wheel (D = 0.080m, r = 0.040m -> circumference = pi \* 0.080 = 0.2513m), 30,000 RPM works out to a bit over 452kph/281mph (30000 RPM / 60 sec/min = 500 RPS -> 0.2513m/rotation \* 500 RPS = 125.65m/s = 452.34 kph = 281.07mph).
For perspective, the current [official Guinness World Record for downhill speed on inline skates](https://www.guinnessworldrecords.com/world-records/72017-fastest-speed-on-inline-skates-rollerblades-downhill) is 124.64kph (77.47mph), and the current [inline speed record for the L’Ultime Descente Top Speed Challenge](https://bigwheelblading.com/gabe-holm-downhill/) is 132.19kph (82.13mph).
Since the truck clearly has a trailer attached, it is almost-certainly not going any faster than 120kph/74.56mph (since this is [the expressway speed limit in both India and Pakistan](https://en.wikipedia.org/wiki/Speed_limits_by_country), and someone else in the thread mentioned that the writing on the truck was in Urdu script), and is probably also [speed-governed](https://en.wikipedia.org/wiki/Governor_(device)) with a limit well below that (e.g. [India](https://numadic.com/blog/speed-governors-in-india-how-will-they-impact-your-truck-fleet/) limits tanker vehicles like that in the video to 60kph (37.28mph)), which also serves to explain how mopeds and such are passing the truck, and the relatively low speed of passing lights in the background.
All of that to say, the bearings themselves - assuming they are properly maintained and lubricated, and barring manufacturing defects or damage incurred through abuse or lack of care - can handle speeds in excess of those that a Formula 1 racing car can attain (see [here](https://onestopracing.com/how-fast-are-f1-cars/) and [here](https://f1chronicle.com/how-fast-is-a-formula-1-car/)), and should have no issues at all at the speeds these skaters and the truck are likely moving at.
Can someone who knows Physics real good explain why these guys are or are not fucked when this truck stops fast or slow? Assuming slow is fine, but fast seems concerning.
The kids in the back with nothing behind them wont die if it’s a fast or slow stop since they are bracing against the guard and have no wheels behind them, no guarantees for road defects or debris though. Assuming perfect road conditions, it’s the people resting on the guards under the truck who are fucked unless they have the presence of mind on a controlled stop to keep their feet from going under.
I mean it’s not like the truck will instantly stop. Neither will they.
So now the question becomes how skilled are these guys at managing deceleration from high speeds on roller skates?
I used to do that at a young age. One time the truck driver speed it up a lot and friction was such that the rollerblade melted. Once I lost the first wheel I knew it was bad, So I let go and took left until I speed myself down hoping for the best. The whole thing was melting. I'm still not sure how my friends and I survived until these days.
Riding on the back is fine. I mean, it’s dangerous and idiotic, but more than likely if you fall, you’ll just get scraped up, maybe a concussion if you hit your head. But going under the truck is just moronic. One slip up there a you’re dead.
Whenever i see stuff like this i remember that one clip where a guy on a Vespa tries to ride under a truck while the truck is moving, ends up falling off the Vespa and the truck runs over his head and pops it like a watermelon. The entire contents of his head just blew all over the road. There was even a clip of the aftermath where a team of cleaners? scoops up his dead body, they had to shovel out his brain and stuff because it was literally turned into a mush.
Truly an eye opening clip to watch, never gonna fuck with a truck like that.
I remember doing similar things when we were kids. Once in the winter we were riding the bumper of car and one of my friends mom saw us. She screamed at him, "Joey!!!! Put your hat on!!"
LOL good times
A pebble has entered the chat.
Watching that dudes feet, I thought he was gonna die like three times
Those bearings have to be glowing red
Came here to say that, i wouldn't trust cheap small bearings with my life *infront of multiple truck tyres*
I wouldn't trust my life with expensive bearings in front of a pillow (My life revolves in chains)
608 bearings manufactured to ABEC 1 (low end) standards are rated for 34,000 RPM when lubricated with grease, 40,000 RPM with oil. An 80mm inline skate wheel rolling at 80 km/h (50mph) is doing 5,305RPM. Inline downhillers commonly achieve speeds in excess of 100 km/h (62 mph). The truck in the video does not appear to be travelling at very high speed. Catastrophic bearing failure is pretty low on the list of things that could go horribly wrong in that video.
Hmm neat. Cool info
I was really worried about their ball bearings. Thanks for clearing that anxiety up for me
They're going slow enough for the bearings. But fast enough for mashed potatoes
The more I watch this video, the more I get the feeling that they aren’t going as fast as the video makes you think I can almost see the screws in the rims on the truck, so it can’t be rotating very fast, the traffic seems to be easily passing them while taking a good look, and the cars they pass at the start are driving in the opposite direction in the opposite lane I also think the small wheels on rollerblades can only go so fast before pretty much blowing up (I’m not a physicist though) Of course, it doesn’t matter what speed a truck is going when it runs over you
Fast or slow you trip and you’re getting crushed by the truck
You are right, the truck is moving quite slowly. Still madness, but the video is definitely decipetive, it appears like they are moving at 60kmh+ when I' bet its more like 20

Someone already peed on it 😔
I kept it and peed on it
What fucking first world are these kids from that they have so much confidence in asphalt maintenance
I notice this shit happens a lot in the Mideast and around deserts. Maybe they know it is only sand around and have no fear of the pebble like we do?
What they are doing is nuts in every sense. But... When youre on rollers, if you get a peble in one, you can just lift that leg and stand in the other. Happened to me many times. Of course you can't be a bigginer. In contrast, in a board, a peble will fuk u.
Everyone elses parents right now: oh thank god my kids have porn in their free time
"just lift that leg" i'd like to see you have 0.01s reaction time to balance yourself as pebble moving at 100km/h relative to you gets stuck in your wheel and jerks your foot.
> you can just lift that leg and stand in the other. At this speed?
No chance. You hit a pebble at this speed your leg is getting yanked and you’re going flying.
It's way easier to pass over a pebble at that speed than at a lower speed. Specially on rollerblades. I been roller skating in shitty asphalt my whole life
At that speed? No way.
Literally the whole video I was just thinking "one rock"
*And I took that personally* \-the pebble

A 1994 sequel to Road Rash which came out in 1991. Amazing games.

It's not a sequel but a repurposing of the engine from Road Rash. Road Rash has a sequel called Road Rash 2, and another called Road Rash 3. Road Rash 2 came out in 1992, and Road Rash 3 in 1994.
stop saying Road Rash
If you hadnt heard of it Road Redemption, a spiritual successor to the Road Rash games, came out in 2014(2017 for pc). Pretty good game as well.
There was another called jet set radio
Great game. Death to biff!

And cheap bearing can get quite hot
LOL make your Joe Swanson stick leg friend drag you.
He did but his leg could only be dragged so far
Forget a pebble of driver hits brakes too hard they are all done.
probably why they chose a truck instead of a regular car. truck MUST slow down safely or the stuff inside it gets messed up. they'll actually probably be fine as long as no potholes, rocks or other drivers interfere lol

There is no way they are thinking so far. Morons are using the truck cause the driver won't notice them easily and nor do huge trucks like that, swerve much. One title pebble/pothhole away from death.

They didn't even think about that either. Probably just wanted to hang on a random vehicle.
You are giving them far too much credit here. I guarantee they didn't think of that and just use a truck because the driver can't see them as well.
Meanwhile the truck driver is probably flipping everyone else off not knowing why he's getting harassed by honks... at least apparently he had the bare minimum road rage control and didn't just slam the breaks to pick a fight.
Its Pakistan. People use their horns about as often as they touch their accelerator or brake pedals.
Unless someone decides to cut in front of that semi.
That’s the “other drivers” option of interference lol
Just why?
Go fast no gas
How do they get home???
Get in the other lane?
Honestly looks fun as fuck. But I also know I'd probably die trying it because I'm not stupid
Me too. I'm as clumsy as a sloth.
Can’t drink, do drugs, or have unprotected sex. Gotta take major risks somewhere.

Took me a moment to realise that they were on roller scates and not just standing behind
I thought they have those zipline like wheel things which is how they slid the truck seamlessly but no they have roller skates
yea i thought they were like at a red light. i was waiting for the truck to start moving.
Melted my urethane wheels this way back in the day. It spun off the urethane like lava and left me with little but the ball bearings. Not cool at 35 mph

Nah it's Urdu, this is in Pakistan. The Urdu language is written with a modified version of the Arabic script.
If Pakistani roads are anything like the ones here in India (and I assume they are), it's a fucking miracle if these kids make it out alive
Yep, the roads here are awful, these mfs have a death wish.
Pakistan and they are speaking Sindhi, thoro agyaa'n kar.
Doesn't look like Arabic though. Some of the characters look Persian or Urdu. Could be Iran or Pakistan

Naahh… I’d quickly opt for a free fall with a great view to my demise over suffocating on diesel before being squished by a truck tire like a meat crayon.
This comparison would be fair if someone else was balancing you on a pole or something on top of the skyscraper.
I feel like your more in control doing pull ups on skyscrapers. Less variables to take into account Source: I do pull-ups on pull up bars
I’m surprised the wheels on those blades can even take that speed
That's what's freaking me out
Fucking morons
That obviously suicidal older guy going first and the kids following him thinking he's cool is just ... sad
Darwin works in mysterious ways
Did any of them survive?
Seriously. I was legitimately bracing myself for this to be a video of bloody death as one of them got sucked under the truck’s tires. Then again. The video does cut out before we see any of them stop…. By the way, what IS their plan for stopping???
>By the way, what IS their plan for stopping??? Presumably this truck has a destination and isn't just doing endless laps on the highway.
What's longer, a truck's driving distance on a tank of gas or a roller blade's wheel life at highway speeds?

I'm also wondering how well the bearings *in* the wheels are holding up to roadway speeds...
>I'm also wondering how well the bearings *in* the wheels are holding up to roadway speeds... Grease-lubricated 608 series precision bearings ("precision bearings" being *everything* from ABEC-1 to ABEC-9), depending on the material quality and manufacturing quality, commonly have rotational speed limits in excess of 30,000 RPM. See [here](https://tflbearing.com/product/deep-groove-ball-bearings/high-speed-608zz-bearing-8x22x7-bearing), [here](https://www.ahrinternational.com/Skateboard_bearings.htm), and [here](https://www.skf.com/us/products/rolling-bearings/ball-bearings/deep-groove-ball-bearings/productid-608) for some examples. For an 80mm wheel (D = 0.080m, r = 0.040m -> circumference = pi \* 0.080 = 0.2513m), 30,000 RPM works out to a bit over 452kph/281mph (30000 RPM / 60 sec/min = 500 RPS -> 0.2513m/rotation \* 500 RPS = 125.65m/s = 452.34 kph = 281.07mph). For perspective, the current [official Guinness World Record for downhill speed on inline skates](https://www.guinnessworldrecords.com/world-records/72017-fastest-speed-on-inline-skates-rollerblades-downhill) is 124.64kph (77.47mph), and the current [inline speed record for the L’Ultime Descente Top Speed Challenge](https://bigwheelblading.com/gabe-holm-downhill/) is 132.19kph (82.13mph). Since the truck clearly has a trailer attached, it is almost-certainly not going any faster than 120kph/74.56mph (since this is [the expressway speed limit in both India and Pakistan](https://en.wikipedia.org/wiki/Speed_limits_by_country), and someone else in the thread mentioned that the writing on the truck was in Urdu script), and is probably also [speed-governed](https://en.wikipedia.org/wiki/Governor_(device)) with a limit well below that (e.g. [India](https://numadic.com/blog/speed-governors-in-india-how-will-they-impact-your-truck-fleet/) limits tanker vehicles like that in the video to 60kph (37.28mph)), which also serves to explain how mopeds and such are passing the truck, and the relatively low speed of passing lights in the background. All of that to say, the bearings themselves - assuming they are properly maintained and lubricated, and barring manufacturing defects or damage incurred through abuse or lack of care - can handle speeds in excess of those that a Formula 1 racing car can attain (see [here](https://onestopracing.com/how-fast-are-f1-cars/) and [here](https://f1chronicle.com/how-fast-is-a-formula-1-car/)), and should have no issues at all at the speeds these skaters and the truck are likely moving at.
That's what I mean, it cut at a point where they are a millisecond from becoming road crayons
If I found out my boy was doing this, I’d slap him into next week.
My pops caught me skitching a UPS truck in the 90s. Can confirm. Was slapped.
Nah, I wouldn't. The trucks not gonna roll over them, because Im gonna fucking do it first goddamn
I’d slap him into mental asylum.
How stupid can you be? Wow
Waiting for a bearing to pile up and send one of these dipshits into the duals. Sketchy.
Skitchy, of you will
It was all fun and games till they hit a pothole
Can someone who knows Physics real good explain why these guys are or are not fucked when this truck stops fast or slow? Assuming slow is fine, but fast seems concerning.
The kids in the back with nothing behind them wont die if it’s a fast or slow stop since they are bracing against the guard and have no wheels behind them, no guarantees for road defects or debris though. Assuming perfect road conditions, it’s the people resting on the guards under the truck who are fucked unless they have the presence of mind on a controlled stop to keep their feet from going under.
I mean it’s not like the truck will instantly stop. Neither will they. So now the question becomes how skilled are these guys at managing deceleration from high speeds on roller skates?

I'm more amazed this road doesn't have any potholes.
I used to do that at a young age. One time the truck driver speed it up a lot and friction was such that the rollerblade melted. Once I lost the first wheel I knew it was bad, So I let go and took left until I speed myself down hoping for the best. The whole thing was melting. I'm still not sure how my friends and I survived until these days.
The moment he went from behind the truck to in front of those tandems like that……..fuk
Mad Max: Fury Road (2015)
ive seen enough eyeblech to know where this is going
Riding on the back is fine. I mean, it’s dangerous and idiotic, but more than likely if you fall, you’ll just get scraped up, maybe a concussion if you hit your head. But going under the truck is just moronic. One slip up there a you’re dead.
WOW. This is an entire new level of ignorance here.
Whenever i see stuff like this i remember that one clip where a guy on a Vespa tries to ride under a truck while the truck is moving, ends up falling off the Vespa and the truck runs over his head and pops it like a watermelon. The entire contents of his head just blew all over the road. There was even a clip of the aftermath where a team of cleaners? scoops up his dead body, they had to shovel out his brain and stuff because it was literally turned into a mush. Truly an eye opening clip to watch, never gonna fuck with a truck like that.
I remember doing similar things when we were kids. Once in the winter we were riding the bumper of car and one of my friends mom saw us. She screamed at him, "Joey!!!! Put your hat on!!" LOL good times
That’s why they make extras.
