The lock picking lawyer is gonna release a service tutorial on this one
Aint no lock
best comment award 10/10 would read again
LPL will be releasing a set of picking tools you can buy on his website soon.
You know that sound a rear wheel makes on a bicycle when it's going dow a hill.
This is nothing to do with a lock😂😂😂😂😂😂😂. I can see how it sounds like a safe though lol
..58 is binding, nothing on 59....
Looks fragile and would never work… I’ll take 2 please haha
Could have sacrifed some wall thickness to make wider pins. Would w0rk better most likely
The pins aren't necessarily load bearing on this scenario. The design transfers the load the the casing on the opposite side of the pin.
Yeah those pins are awesome, but look weak.
Still I appreciate tiny mechanisms. Wild how small of tolerances we can make things.
@@dalejrjunior1298those pins are made of tungsten, you’re not messing them up, i’m sure the people who made multiple iterations, tested them, improved rhem, then decided they were good enough to unveil knew what they were doing
@@dianapennepacker6854The load spread out amongst all of those makes it so they can individually do less work and survive
I don't know if I'm looking at a lock, a ratchet or a revolver!?😂
Or a fidget toy....
Whatever it is, I think I want it
May be it is a racheted revolving lock 😁
It's bicycle rear hub
I want
It could even be a engine.
Looks very good machined, but it also looks like it's very sensitive and I'm not sure how it will react on high torque. The smaller you build things the harder it is to make them robust enough.
I disagree the wheel will push the pin directly into the hub, the effective leverage it has to break those pins is almost 0.
As long as there’s is dual or quad pin engagement at any given time, which we don’t see in this video, then I think it would be quite a good design
There are plenty of small pins, together they will be able to do the heavy work.
from what we can see only 1 pin engages at a time
I don't think that would be the failure point. What's more likely is dirt/sand grains and oil/chain lube working their way behind those tiny springs
Looks like alot of friction for something that's gonna spin literal thousands of times in a short amount of time
When you combined a machinist and a locksmith!!!
Damn, watching this for the last 568 hours and he is still spinnig it!
Sounds excessive
Rookie number
Yeah,....me too ....nothings happening,gets boring!
Was waiting for him to turn it backwards 😒
I don't think so.
Looks extremely good for torque when clean and new, I just wonder how those little springs and pins are going to hold up to dirt and moisture.
У меня обычные 6 пластин,никогда там внутри ни грязи ни влаги нету. Если ещё и пыльник хороший то просто по время обслуживать и всё будет хорошо
They won't.😂
past a certain price point it goes from being a matter of functionality to a matter of how satisfying the sound is. it does sound nice but i can’t imagine it functions any better than traditional ratchet pawl hubs.
and for those complaining about grime/etc, all low-backlash hubs have the same issues. with pawls, they get gummed up and stick disengaged, and they slip. if you want to beat on your bike and not clean it, don’t spend several hundred dollars on a hub?
So producing an expensive hub is an excuse to make it high maintenance, where cheap ones will be low maintenance? I don't agree with that
@@SnootchieBootchies27 it’s a toy for wealthy bikers
No, the upper and lower pin are in phase. So they are operating in 3 phase. Every 4th pin works together. The nice thing is how quick it would engage. You would have to use a really light lube to avoid gunking up the pins. There is not much contact area, and the contact area is angled so it pishes in the direction of movement, but also pushes out against the hub bearings. So it wants to push the hub open as torque is applied. As the bearings wear out, there is a chance it would slip under heavy torque.
“ No, “ like you were in some angry internet debate with niche “communities” before you typed the comment😂
Just a tiny sand or dirt would stop it.
That is concept hub model, not even installed inside rim... But we all know - all thech that we use today were wild concepts 20, 50,100... years ago... For example chevron gear teeth was taken into cars - by Citroen in year 1900... In 2000 only it was installed inside DT Swiss Hubs... Which are not 100% reliable till now...but 100 years passed...)))
This tickles my brain in just the best kind of way...
Same
Maintaining parts til they break, this doesn't look friendly with grease. It could work with transmission oil, but it'd need to be sealed. But in any situation, I wonder how long it would take to round the edges off the pins and latching mechanism
A light EP-0 grease would probably be fine. Put heavier springs in the assembly.
Notice how the pins are staggered? Thats probably to limit the slop when the drive reengages. However it also means ALL of the force is directly on ONE of those pins! Imagine how quickly those would shear off
Seems like a terrible direction to side load those pins against the bores they ride in. I'd like to see what comes of it but my first impression is that its not ideal.
now imagine a bit of grime on those precision parts and the nightmare of cleaning it before failing to reassemble it as a tiny spring flew off somewhere. nice engineering but 0 practicality
@@rhetorical1488 imagine having to clean what I assume is a blind hole thats 1-2mm wide, fking nightmare and I thought cleaning the splines of a dt swiss ratchet is a nightmare
@@trailfork7815 hehe i have the dt swiss its not so bad with qtips and a bit of time. this would require a clean room and watch making tools 😅
I'm sure the both the Lockpicking Lawyer and Hambini would both have some comments about those chintzy lock pins serving as freehub mechanisms... not to mention the side thrust that it's gonna generate
@@tstodgell he would take longer to get it out of the package then taking it apart😂
I love mechanical sounds.. I remember growing up before they electrified everything we used springs for everything. I was using a hand crank the other day and it snapped back and the sound of the spring reverberating in the cabinet sounded just like my childhood ❤😂
I just think its fucking amazing the shit that we can design..if the design may not seem feasible for the application build it and share it you never know who can use it for something else
In this instance, it’s for a bike hub.
Probably similar design to those small turn
That is an incredibly selfless, all in it for humanity pay it forward kinda comment. I’ve got warm fuzzies and a temporary new found hope for humanity.
Looks awesome but id wonder about the heat all the friction on the sides of the pins would produce after a long coast. Even with grease it would eventually warm up id think
The water cooling is in Version 2.0 😂
I have always been curious about how that worked 💪🏾
That’s so relaxing to listen to which is so odd to say.
As a bike mechanic. This little vid curled my toes. Amazing tech.
Why do this look like a mix of Chris King and traditional pawed freehubs?
It *'do'* not look like a combination of anything else bicycling related...
i always wondered if loud hubs loose more energy through friction
Yes... *nearly imperceptible* in 'Real World Application' because *Who really cares How 'FAST' They Are Going -> When They Are Not Pedaling...?*
And, yes, it is easily 'measured' with a bare spinning wheel... *harder to tell when that relatively tiny friction has to 'SlowDown' over 200# or 90kg of Bike&Body Momentum...*
JestSayin'...
Concur
It's not really correlated. You could also have more friction but almost silent (like sprag clutches typically have).
Those tiny pins are gonna sheer so fast
I just don’t know if this amount of complexity is feasible. It looks like so much could go wrong. I’ll take 10
As an engineer/machinist, it's beautiful!
As a cyclist, it's too expensive.
The sound is amazing in headphones
I keep imagining one with a drum brake type of engagement where as soon as it goes in the right direction plates expand out into a cylinder griping it. The harder you peddle the more it presses into the drum.
For now I am happy with the best design yet, Onyx
Best believe we pulling it apart and stretching them springs to changed the noise 😉🤣😅
Waste of time. Reminds me of how obsessed people r with exhasts just to say it sounds cool
You realize most strange hubs like this don’t have pawl/spring mechanisms right? What spring are u gonna stretch on a magnet driven ratcheting system? There aren’t any.
That looks hypnotic, and I love it
It sounds pretty. It looks pretty. I love how there's no room for backslip. I have concerns about what happens when actual torque is applied.
Looks interesting and as long as they can seal the mechanism completely, it should work. If they can’t, then when the pins gum up it’s over. The failure mode would likely be stuck in the compressed position so it wouldn’t lock anymore. Time will tell I guess.
This is exactly what I want my back rim on my bike to sound like
My engineering brain is in love with this
How much friction would you like to ride with? -YES!
i like how they machined the lines for the top of the pins to snap off uniformly.
Looks like it can take some torque, but all that friction would make for one hell of a back-drag on the output.
I think it'll take more torque then people will give it credit for but not like the ratchet wrench they assume what the mechanism is for based of the sound
At first I thought it was a new radial engine design 😂
Looks super draggy
Best fidget toy so far!
Incredible. The next Kappius Components.
My youtube feed is so diverse I couldnt tell if this was a lock design, a revolvers cylinder for a new gun, or a weird socket wrench ratchet tool
That is so satisfying, reminds me of something in my childhood.
This is how modern high quality ratchet spanners are made. This would be as tough as a nuclear bunker
Lmao i thought this was a new style of ratchet wrench 😂
So satisfying to watch
This is a freewheel mechanism of the freehub type. The most reliable ones use big loud clicky pawls, or star ratchets. This assembly of fine pins and tiny springs has no business being on a bicycle hub that will be lubed with grease and operated in temps from -10c to +45c.
I watched 3 times. Só satisfying.
Great concept. Now let's say we scale it about 100% and start working on some space stations.
The side load is fully supported by metal... A decent bit of it too i do think you could work this better though, only need like 4 throughout the entire cylindrical face... Could space them out more to increase bore size of those lil guys but still would work
this is relaxing ❤
That looks pretty cool for anything needing zero back lash
Id make sure the angle of the attack angle is pulling the pins in, and actually locking the mechanism. Otherwise this eill just slip under any high torque
It is for rear bicycle rim... Just in case you were wondering what you're looking at.
One third of the teeth are immediately engaged, so there is no chance of load being applied when the teeth might slip a notch. This may be a feature in search of a problem. Do dtswiss teeth wear out?
I thought this was a new revolver lockup mehcanism at first, very appealing to the eye and ears.
Now I can chase tiny hub springs across the room.
Wild.
Spring break is just around the corner.
Omg 2024 is sooo beautiful thank you
Assuming there's going to be cross hub engagement, this thing seems like it would have like 12-16 pins. Imagine the engagement and noise from the standard 6.
This just looks like an amazing fidget spinner to me lol
I feel like they're definitely gonna shear pretty quickly
This would be great for electronics work, but wouldn't want to replace my alternator with it.
I want this for all my rotary controlled devices 😂
Absolutely zero slop! I love it!
I could stay lost in that moment.. forever!
This sound is so satisfying to me
Imagine going downhill with this hub🤤🔥
Love the sound.
When they twisted it slowly, it sounded like the smallest Harley Davidson.
That is very satisfying to watch
There has to be more footage to this video clip, it's the before and after.
Okay so i imagine the conscept here is a tighter fitting ratcheting mech, and an infinite ratchet method
The lockpick lawyer has the key to this already
damn this ratchet gonna go with BRRRRRRT
That sounds so good.
Needs to be implemented into ratchets for toold
If **FOUR** *Pins Engage* (at a time), this may be as good as I9...
I still *prefer *ONYX** and *DT-Swiss* Hope Hayes King Hubs before Industry9...
I say *"Four PIN Engagement"* because the *cutaway* is representative of ¼ or 25% of the Hub, and it does sound 'concerted', that is; it sounds like multiple pins are clicking at nearly the exact same time as you see each 'single' pin 'click'...
Mesmerizing!
This is how diving watch bezels work. But with 1 plunger.
I feel like it's 1989 and my older brother is showing off his bike
Sicherlich ein gutes Konzept um wenig Leerbewegung zu haben bis der Freilaufkörper die Nabe dreht, aber garantiert nicht sehr haltbar bei hohem Eingangsdrehmoment..
PS: krasser Sound, wenn man darauf steht 👌🏼
It looks like those pins aren’t engaged at the stake time. That would give the indexing three times the number teeth on ratchet. All the load would be on a single pin.
I see at least two pins engaged simultaneously (top and bottom of the cutaway, cover the middle two with your finger to see it more easily), it looks like this occurs in every third pin.
now this is asmr
The sounds give my brain the good itch 😩
Maintenance NIGHTMARE 😂
Strong as a chinchilla wrist!❤
I see pins failing, between going out of round because of too many engagements, and sticking once debris gets in all those springs.
Yet, the fuel pump still has to stop 37 cents early a cold and rainy day!!
I'm pretty sure they've already cracked this mechanism. What do we need to keep reinventing the wheel (literally)?
I assume it's meant for low speeds, any faster than 1000 rpm and those pins are getting erased
Love the sound
Now thats a true fidget toy
We who watched more than once..
👇🏼
Anything with spring-loaded pawls or dogs are cool.
it looks like they are sequenced so that some are in the locked flat position and others are on the incline, which seems like it would make it super weak
Stop it you're driving me crazy😅
Sounds great
Красота и минимальный люфт
Would it be wiser to rotate the angle of those spring loaded pins 90° clockwise?
You'd be ratcheting the freehub body clockwise then.
What would happen if you had one pawl facing the other way? What if it was manually actuated instead of self actuated.
What this looks good at is engagement with near zero play and smooth coasting. What is concerning is the small number of pins taking that shearing force at any given point in the cycle. I'd take slightly more slop in exchange for having six or more pins fullyengaged at a time. This looks like it does between 2-3 at most. Still, really cool concept.
