What do you make of this carbon process? ⚙
Can you please add captions translating these Farenheit and psi things for the 95% of us?
If it helps, 100psi is the pressure of my rear tyre and Fahrenheit 451 is the temperature that paper catches fire. :) @@craesh
I love it!
After almost 30 years of working with composite materials as a blue collar and as a designer in engineering, I have now come to the conclusion that there is simply too much hazardous waste being produced.
Pretty awesome stuff, but funny that, after all that automation, they build the wheels by hand. Maybe it's editing, or they simply true them by hand, but it's amusing nonetheless.
Loving these factory videos, excellent work Ollie.
@@kulchatha4657they're still great even if they're ads. The good thing is they're clearly telling you it's an ad. Even the thumbnail said it.
I like to know how stuff is made and I'm sure lots of other GCN viewers do.
Always super cool to see how the magic is made 🙌 Are there any other factories that you would like to see us look into? 👀
@@gcntech Campagnolo please but I bet they won't let you in !
A company back in the 1990s known as Spin, was making a tri spoke wheel with what they called thermoplastic carbon fiber. It seemed like they were using a similar process to what you showed, but maybe not quite as efficiently done. Their product was significantly more affordable, but heavier than the competition. And there are techniques of recycling, Carbon fiber. There are machines that will burn away the epoxy, leaving behind dry fiber I saw a demonstration where they loaded in a broken bicycle frame and out came just the dry carbon fiber strands.
You are going to expend fuel energy, put bonding chemicals into the air, to recover broken tortured fiber that you do what with? What nonsense, just throw it out.
Thermoplastic/carbon fiber bikes were made by GT(?) in the '90s. The advantages were recyclability (not sure how), impact toughness, and the improved damping you mentioned. Disadvantages were inferior strength-to-weight and stiffness-to-weight, and that components like downtube shifters and cable stops needed clips to attach them because they couldn't be glued on. Interesting tech, thanks
This is my favourite GCN Tech video ever! The one question I'm left with though is how do the two halves come together? Certainly the spokes would pull through a seam down the middle and the tyre pressure would push that seam apart.
I would imagine that the heat and pressure created inside the mold softens the nylon and forces it to fill the seam between the two rim halves, in like fashion to the earlier process where the strips were patched together and pressed at high temperature to make the flat annular disk for the rim.
@@johnbarron4265 Don't forget that spokes are installed with a great deal of tension and see even more in use, especially drive side and while braking. All of that tension is concentrated into tiny little spoke nipples.
@@DavidMulliganah now don't be a nipple twister
Same, without any carbon across the seam I'd worry about it too - though I expect they have solved it somehow.
what about the weight/stiffness data comparaison with prepreg carbon ?
Are these wheels actually cheaper because of the advantages you've been mentioning? Or does the manufacturer make extra profit this way?
Because it is largely a new technology, the price initially will be high to recover R&D and investment costs (machines etc.).
But at least in theory, over time when the technology gets more widely adopted, the price will go down.
@@erikvanderveken1408 i just looked £2.100
@@erikvanderveken1408 I'm looking for a price comparison right now. Not eventually.
Anything new (such as new material = new product = new machines = new labour personel = new techniques = new training for work = more expensive advertisements etc.etc.etc…
@@Epiqe
new material - cheaper material
new product - no comment
new machine - old processes ask for new machines all the time too, everything has a lifespan
new labor - freed from old work
new techniques - same, just replace older
new training - a) all workers learn as they work anyway b) new techniques are more automatizes, less learning needed
more expensive ads - new product is easier to advertise than anything same but 1% ligher/stiffer/more aero
Thermoplastics composite nylon in cycling has been around a long time. Examples as Modolo downtube shifters and brake levers from the 1980's and GT made a full squish MTB out of the materials. I do have a road tubular pair of rims made in this same material sold by a company in the UK called Matrix. Its a deep rim and I'm using with a rim brake. (Note: Not the same Matrix company or brand as USA Trek owned.)
Really? I would expect thermoplastic rims to be completly incompatible with rim brakes. The glass transition temperautures for most thermopatics is in the 50-150c range, well under temperqtues that rim brakes see.
@@BenFriesen1 Skyway Tuff Wheels (nylon for the regular ones introduced in the 1970s, carbon-reinforced nylon for the graphite ones that were introduced in the 1980s) have been used with rim brakes for as long as they've existed. Skyway even sells special brake pads for use with them, and they have since at least the 1980s:
"The Skyway BMX slim brake pads have been designed for use with the Iconic Skyway Tuff wheels. Available in many colors to compliment the Skyway Tuff wheels, this pad features a threaded stud and is compatible with modern V-brakes, old-school caliper & U brakes."
Alloy rims are 100% recyclable into new alloy rims or beer cans. Most of us don’t need carbon rims.
Yup, don’t need that fancy stuff anymore, not racing doesn’t matter and over 50
Carbon fibre is the corporate bike industry shitting on the idea of bikes being environmentally friendly and selling it like it's an advantage. Pricing them like motorbikes isn't helping either.
Nope of us need fancy stuff, but we want. You gotta create something that is fancy enough for rich people to spend their money.
Most people who own bikes also dont ride them
Most of us don’t need bikes either!
Good video! I had heard Trek was on to this and saw that Lauf was using them on their gravel bikes, so cool to see the process. Will be curious to see how the MTB wheels are and if it expands to more aero shapes and sizes for TT bikes.
You can actually see in 13:12 there is a TREK sticker on rim while in drill machine.
@@funLad80 Yep, Aeolus is their Bontrager model
@@funLad80 also, Aeolus (visible when they pull the wheel out of the mold) is a trek wheel model
Same I'm curious though from this video I still think traditional carbon fiber is better so far
I'm still going Ibis S28 for my next rims I'm building for my enduro bike
If you visit this company's website, you will be surprised to find the wheelset price. Despite the claims of saving human labor and production wastes, the MSRP for the gravel wheelset is quite steep.
Well of course, cycling is currently regarded as one of the biggest markets of suckers with money out there.
Another rip off for us all to buy at thousands for a set of rims omg .... So now they want us to buy wheels and carbon with no waste and no human labour ? No jobs then just profit ? Nice pmsl
@@gordonhenderson1965 Buy all the machinery, build the required molds and make carbon wheels yourself. Do not violate any of the hundreds laws regulating the industry in the process. At the end let us know how much you are going to price the parts you produce...
Ollie did also spend a reasonable chunk of time discussing how much time, effort, expense, and expertise, went into working out how to make these things though. Much like everything else you've just got to factor in recouping R&D etc
@@andreamig1 Why should I be bothered about their machines? If it is more expensive than traditional tech and provides few benefits (like nebulous recyclability), why pay the premium?
Nylon cabon 3D print filament exists and I have used it before personally. It is very lightweight but it's integrity gets affected quite a good amount from UV rays i.e. sunlight. I'd try wheels like this, but not without some form of clear coat or at least 1-2 layers of paint to protect the nylon. These days, general carbon wheels are built extremely well, it really takes quite a lot of force to actually break or fracture a carbon rim or frame, and epoxy is well resistant to UV rays unlike nylon. I'm not saying nylon carbon is worse than traditional methods, there is definitely potential, but selling wheels without adding some paint coats for protection from UV rays concerns me. This would be great though for things like carbon wheels, bottle cages, and other smaller more accessory products.
Interesting you say that about the UV sensitivity of the carbon. During the whole video I was wondering how their application could be used for wind turbine blades. Currently, once a wind turbine meets its end of life the typical disposal methods usually destines the blades to the land fill. This aspect of the life span of a wind turbine is under research, mainly different recycling methods, and I was wondering if this sort of tech could be used to replace the current composites used for blades so that they may be recycled better.
@@BeyReaper I think there is potential but my concern is if it’s bare nylon carbon being used vs nylon carbon coated in protective paint/coat. I think there is a use case for it as long as it’s protected.
My friend broke so many carbon rims, he had to go back to aluminum.
Carbon epoxy cracks after 800 hours of use and has zero protection from UV. That's why all the carbon bikes have the super thick matte paint jobs to protect the frame.
I came looking for a comment about UV stability. Also curious as to how it manages moisture
just ordered the shift Am mountain bike wheels and the shift CR45 road wheels. $937 each set on sale. Great price for American made high quality carbon. New to cycling, excited to see how they feel.
What happened to the last future - grapheme?
Great video, Ollie! I love your behind-the-scenes looks at things.
Ollie loves a snoop through a factory 👀
I absolutely nerd out with videos like this. Great work, Dr. B.!
Nerd out with the biggest nerd out there 🙌
Ollie - easily the best explanation of the traditional prep-preg process I've ever soon - great job. Also very cool new tech to boot.
Ollie, I’m getting more and more impressed with your videos. TV broadcast quality.
Fascinating. Another great learning experience. Thanks, Ollie!
Great reporting journalism Ollie!
American-made wheels is certainly attractive to me (and almost unheard of.) Hopefully Forge & Bond will expand to road wheels at some point and hopefully lower prices over time as they sell more wheels.
They seem to be sold through Chris King.
If you notice in the video, there is a Trek/Bontrager Aeolus road wheel being made. Specifically the Aeolus Pro 37V and 49V for now.
Super cool to have bike parts made close to home 🙌 Do you think you'll be picking yourself up some Forge & Bond wheels?
Dad did a lot of design work with polymers in the telecom industry 80's and 90's he'd come home from trade shows with things like a briefcase full of briefcase handles of different blends, injection molded models of injection molding machines, and for me the star of the show, a glass filled polyamide (nylon) g clamp, truly the king of the thermoplastics.
I don’t understand how they “weld” together the two rim halves in the mold. I assume that there are further carbon layers overlapped to join the two rim halves, otherwise the finished rim would have no structural integrity. But I cannot make out in the video such a detail in the process.
I know a llittle of how such things works, in the traditional way yes, you would need some overlap.
in this way the use of nylon squeezed and heated together, will create a bond just as strong, like the guy said, nylon matrix can be reheated over and over with no loss, so it will melt and set in the mould, I know of some Glue's used for bonding CF prop shafts to metal parts within the F1 industry, it's aerospace glue, stinks like fuck... and I mean it's horrible a/f, but in 12hours that glue is stronger than the rest of the carbon fibre part, the carbon would break first before the glue would ever fail.
makes you wonder though.... just make components out of the glue alone lol.
and they will have used something like FE mapping and real physical world mechanical stress testing to prove the strength of the part (In this case a wheel).
so they will be good.
the real question is... are they stronger/lighter or same equivalent as traditional layup.... and at least cheaper, seeing as how the process is robotised.
That was my question too-the way it appeared, there would be a “seam” running along the spoke bed that’s just stuck together with resin and no fiber reinforcement.
just like in a conventional weld material from two parts mix up, here the ends of carbon strands interlock.
Yes, it's not as strong and effective from standpoint of material utilization, but sufficient and surely not presenting a distinct seperation like a glued joint.
It is a cool process. But the waste is still not really fully recycled, instead it is down cycled to a lower grade product. It is something to keep in mind since traditional Aluminium can be 100% recycled to the same product.
For the sake of accuracy, (and definitely, 100%, not pedantry), usually, reinforced concrete is a mix of cement, sand, and aggregate, (i.e. stone of varying sizes), forming a matrix surrounding steel reinforcing bars (But there are other ways of making reinforced concrete.)
Very well presented Ollie. An interesting video
Aeolus? Are these Bontrager wheels?
EDIT: Ollie mentioned Trek at the end, so yes.
@@ojtibi9906 damn! Bontrager got some serious tech in their wheels that no others have!
Very cool tech! Pro job on the video GCN!
That is the coolest thing I've seen in ages!! Great video!! Thanks 👍👍👌
Very cool! Great job 👏
The carbon footprint of traditional carbon fibre is insanely high and we should all be aware of that when we buy a new bike (I’d suggest it should be labelled on the bike and certain components, on purchase, the carbon footprint print and a score for how easy it is to recycle) . It’s good we’ve developed a process which is less intensive. Still happy with my alu rims and Reynolds steel frame though, but I’m not looking for marginal gains and appreciate it’s a different scenario if you race.
Titanium leads the way.
Fascinating Ollie ! Nice one ! 👍
Excellent report. I suggest following up with a ride review on those wheels.
I recently picked up a set of the Bontrager Aeolus Pro37V's using this process. The finish of the wheel is quite nice.
Sounds like a great set of wheels 👌
This. Is. Awesome. Ollie-and his stoke-was perfect for this piece!
Thank you , Ollie. Interesting, and well explained.
That's Ollie in a nut shell 🙌
I ordered Chris Kings for my new bike. Looking forward to delivery.
Interesting, well made video. Thanks
Great video but you missed the details of key stage. How are the two sides bonded together. That for me is the most critical as it has the spoke forces applied there and could catastrophically separate the join failed.
I'd imagine there's a reasonably sized overlap down the center: so the spoke nipples would go through both the left and right side of the rim and the 'bonded area' would be wider than the nipples. So the rim bed would be "double thickess" and the two seams not in contact with the holes.
The great thing about using thermoplastic for the matrix is it how can be fully melted again and again, so to answer your question, the two halves are likely joined in a process that would be a sort of combination of compression molding and conventional casting/drop forging.
With resin carbon you have the matrix starting as liquid, then compress and cure it, with thermoplastic you heat the material whenever you need to, to make the matrix into a liquid temporarily.
The reinforced concrete you referred to is concrete (not cement) with the addition of steel to reinforce it, used in tall buildings, bridges etc, the cement you referred to is only one of the components used to make concrete, concrete is made up of sand, cement, aggregate and water, this version of concrete is used in non critical applications such as sidewalks etc, so concrete itself is a composite material, reinforced concrete is a more advanced composite material
One thing I saw on their website - no rider weight limit. The price is not that bad for a nice set of Carbon wheels. Looks like they only come made with I9 hubs, so kinda crappy I can't customize what hubs I want (I'm partial to DT Swiss) but having it all be USA made, that's worth paying extra for me.
RAT-TAT-TAT-TAT-TAT-TAT-TAT-TAT-TAT-TAT-TAT-*yelling* "why don't you like I9 hubs?-TAT-TAT-TAT-TAT-TAT-TAT-TAT-TAT
One thing worth noting on the thermoplastic matrix materials is they do require more infrastructure than thermosetting resins. Room-temperature epoxy resins can be used to laminate parts with no other machines. If you want better consolidation then you need a vacuum pump. Prepregs add the requirement of an oven. In order for the thermoplastic composite to come out well it has to be autoclaved. The nylon never gets nearly as thin as epoxy resin, so you need more pressure to force it to flow.
Pretty cool and interesting, also the fact that it appears a lot more environmentally friendly is a big step forward. Would like to know if there is any perceivable performance / feel difference between traditional pre-preg and these modern forged components
The eco credentials are super cool 🙌 Would that make you want to buy that product?
Environmentally friendly how?
@@The_Ballo The video covers it but mainly on 2 axis. On one side, the pieces can be re-molded into something else, meaning if your frame breaks, it could potentially be recycled and turned into another item, whereas tradional carbon fiber is disposed of in the trash. Second, the overall making of the parts seems to be much less energy consuming - the video doesn't go much into detail here but notice how with epoxy carbon the storage is a freezer, later an oven, etc.
Thanks for another informative and entertaining video, Ollie!
Inform and entertain... If Ollie had a tattoo that might be it 😂
@@gcntech Maybe it should be a challenge, such as if a video gets enough likes!
Who suggested that tattoo? Alex?
Great video Ollie, VMT👍
Really awesome video!
brilliant stuff!
I'm guessing this nylon matrix wouldn't stand up to temperatures generated by rim brakes. Particularly since I did not see any evidence of brake tracks on the edges of the rims.
Rim breaks are doomed , BUT , disc brakes are ripping the spokes through the rims and causing huge cracks from one spoke to the next on most bikes but there keeping that out the press and media ? Have 3 friends with cracked rims ? Discs cause the breaking forces to use the spokes not the rim so spokes can't take the forces and ruin the rims ? Not good but all kept quite .........
Especially given traditional carbon rims have failed under heavy rim breaking.
Rim brakes are not doomed, I have enough medium and long reach calipers to last the rest of my life. Even if the bike industry tries to force me onto cheaper tech they won't be able to.
@@curtisducati What's even more scary is that on my MTB's, for which there's no question that disks are better (At least for anyone who rides in mud), I'm still getting failures where the rim cracks from spoke to spoke, and this was on Hope XC wheels - after the second failure, rather than bothering warrantying it again I just replaced the rim with a WTB one that had the same ERD and that's been perfect since though. I've had a load of trials bike rims fail like this too, but trials is the only MTB sport where rim brakes are more popular at professional level than disks, so the rims aren't necessarily tested to withstand disk braking forces. Trials riders grind the braking surface of the rim with an angle grinder to make it as rough as possible, so the brake locks 100% solid, but this means it howls very loudly when the brake is dragged while rolling, which is why I'll stay with my nearly silent disks instead.
What's a rim brake?
Awesome video. Thanks Ollie!
Glad you liked it!
Super interesting! Very well made film, and excellent presentation by Ollie!
Thank! Where should we send Ollie next? 👀
I think this new nylon composite material could also have very good application in bike shoe soles and saddle bases, where it is very useful for the end user to be able to custom mold to their liking. I wonder if this is the technology also licensed by Lemond bikes.
Oh yeah, you can do this with FusionFiber! Just heat it up to 300 degrees then stand on it for a few mins as it cools. Eventually, you’re left with a perfect form of your incinerated stubs where feet used to be. Very comfortable on the bike once the wounds heal.
Ollie went super saiyan with his hair style for this one.
Strength testing? Failure modes compared to regular carbon fiber methods?
That was really cool. I love how they make it videos
In practice, recycling is still really tough and probably not economically viable except rapid downcycling. If you want to preserve fiber length then you kind of have to carefully pick the pieces apart and sort them by fiber length. The more common approach is to basically put the part in a blender and melt it down into a short-fiber reinforced nylon, which has applications but is not nearly the same thing as continuous fiber composite.
Very nice video guys! Something that got missed on the way, or I didnt hesr it, is the increased fracture toughness of an thermoplastic material vs a thermoset material, so you dont have to worry about impacts on the wheel. Nevertheless, thermoplastic material degrade faster over time compared to to thermoset material. I would like to see a wheel made of a material with bought materials combined, like its done in aerospace.
finally some good video from GCN!
0:08 for anyone confused, "noughties" probably refers to the decade of the "aughts", i.e. the 00s, more specifically the 2000s
Utah is AWESOME! There are some great cycling races here! Tour of Utah, Kokopelli Relay, & Salt to Saint, to just name a few!
We have very safe cycling trails up and down the Wasatch Front (Ogden to Provo). With our population boom over the last 10-15+years, Salt Lake City is incorporating more bike and pedestrian infrastructure as road improvements are made.
Aerospace businesses run deep in Utah as well.
This is awesome content. It's crazy that in the last 2 years, UA-cam top-end content has reached where cable network content was in the 2000s, quality-wise. I guess there was a convergence of price for equipment going down and general self-taught understanding of how to make content going up.
We're always trying to push our content 🙌 Great to know that you are seeing the improvements - Can you think of any other factories you would like us to visit?
@@gcntech3T
So no good for us rim brake folk then. Brake tracks can get up to 250 degrees and would melt this nylon!
Ollie Im very surprised with your knowledge explanation! top! Merci!
j’ai etudie les polymeres a l’universitie 👍🏼
Neat. Now make a rim braking variant.
Then I'd actually switch carbon wheels.
These have the potential to be forever wheels, would just need a replaceable braking surface so it could be swapped every 15 years.
Nevermind I had convinced myself bc of all the hype that they'd have improved thermal properties as well. Back to my original idea of a shallow alloy rim with a non-structural composite aero section.
Ollie, you didn’t say what city they were in but Utah is where I live and I bet you were within a 100 miles of my home town. Utah is a great place you should come back and ride here. Hope you had a great visit.
I wonder how well this process works with core materials. My two concerns would be
1.the high heat and pressure requirements may eliminate the possibility for lower density and non-temperature stable cores. Ironically eliminating things like thermoplastic foams/honeycombs.
2.the matrix material may not have the appropriate fluid properties to adhere well to something like al/nomex honeycomb. Thermosetting resins can bond well to the small contact area because they spontaneously form "fillets" due to their adhesion and surface tension and I suspect molten nylon is a bit too thick.
Great video Ollie.
That boy is in his element
Just bought the Chris King GRD23 wheelset using the Fusion Fiber, personally I think its just a marketing gimmick and 99% of riders wont notice the difference. But they do look very very cool.
Love this. Thanks for doing this video. Any idea when frames will start being made of Fusion Fiber? Also, did they tell you the cost difference between Fusion Fiber and the equivalent pre-preg carbon fiber? Thanks!
Guerrilla Gravity was making frames with the same material
If this is a cheaper way of manufacturing carbon, the industry will adopt it in no time since he industry loves lacking on the manufacturing process but charging you more for the priviledge.
The most important questions, is it light? Is it stiff? Is it strong?
You forgot the more important question: is it UV stabilized. Nylon doesn't fare well in the sun. Neither does resin, but nylon less so.
@@The_Ballo That color takes more sun energy in.
11:20 - he bends it easily with his hands.
13:45 This is the absolutely hardest maintenance task to do on a bike. I expected this specific task to be done by a machine.
I would rather work in a mine than straightening bike wheels.
Best episode of ‘how it’s made’ yet! Well done oli!
Nice advertisement for the sophisticated machines of the German company Dieffenbacher 😉
What's the price, weight and performance difference?
Look at ENVE and Chris King wheels as they are using these rims.
Website says gravel rims are $425, 380 grams, and "No rider weight limit". Same for XC, and I didn't look at the other MTB.
@@trwilliams22 Also, Revel. I found some 4 year old videos about them.
Kinda really about time! Carbon fibre is such an old technology and definitely not as strong as it Once was with the dry layer process in the middle for all this gone mad weight saving! You will see split dry fibres in snapped Carbon fibre in the newer process of weight saving but we used to call it the cutting corners friday special gone daily! Carbon frame on pro's bikes will be double the layers say on a headtube to what you would buy from the manufacturer if wanted the same bike for example! Been there done the job know the tricks of the trade!
Curious how the weight compares to high end pre-preg?
Very cool new tech - hopefully in the future the cost will come down, much like most new things in the bike industry you will need to mortgage your house to get a pair of these.
Thank you for actually showing the manufacturing this time.
interesting seeing aeolus branding on the tooling - looks like they produce bontragers "oclv next"
Not surprisingly the construction is only possible for hookless. Also as someone also noted it's also a bit heavier than resin which will increase weight on the outer wheel - I'm not quite sold.
I see no reason it couldn't be made to work on a hooked rim. In fact, this materials seems to permit processes that make hook forming easier.
Being left uncoated or untreated otherwise, I'm wondering how they managed to overcome the strong hygroscopic behaviour of nylon. Nylon can absorb up to 8% of his weight in water.
you kind of want to have nylon absorbing water, most of the "nylon" we are used to in the everyday is almost fully saturated. Dry nylon is brittle and quite stiff, this applies to basically almost all plastic polymers, most nylon products go through a conditioning chamber to be water saturated before the end of the production cycle.
Basically you want dry nylon in production to avoid, generally, hydrolysis of the polymers due to boil-off and the stringy/messy nature of wet nylon. During normal use you definitely want wet nylon due to the more flexible yet resilient nature of the wet polymer.
@@andy_liga I think the concern more so regards internal stresses and holding dimensional tolerance on a part where the material is hydrating after manufacture.
Union Snowboard Bindings from Italy have been forging carbon for quite some time. Campagnolo rims have a finish that is even better than these featured rims, plus they don't drill the rims, the holes are moulded in. Sorry to urinate on the bonfire.
GO Ollie GO !!!!
But, as a German Carpenter, I'm proud to see, that your wheel company, for their production uses almonst complete our German Maschines!
Diefenbacher was also our 13 prime minister and came from Neustadt Ontario. 👍🇨🇦
The oven looks like a Vault from the Fallout games, but that sure isn't a shelter I'd go into :D
Welcome to my neck of the woods. Hope you got to do some riding while you were in Utah. It’s an amazing place.
Welcome to Utah. I think you will find that Utah is home to a huge amount of bicycling industries in a spectrum of aspects of cycling. Great segment Oli! I am one of those anti carbon old school curmudgeons that thinks carbon bikes are soul-less and a blight on cycling, But this was really cool because of the recyclable aspects. Don't get me wrong there is a place for carbon bikes and bike products but I hope to see a return to more traditional materials but used in a way that takes advantage of modern manufacturing processes. I think there is a solid place for the Forge & Bond products. PS. When are you and GCN going to come to Ogden Utah and do a story about the hidden / secret mecca of the cycling world? You can stay at my house. Cheers - M
We also love a steel bike but you can't not enjoy the process of making these carbon beauties 👀 We've been doing some great riding around the states, El Tour de Tucson was amazing 👉 ua-cam.com/video/H9YostVYD40/v-deo.html 🙌 - What do you love about the riding in Utah?
I Love the variety of terrane that is locally available@@gcntech. Utah is special in that there is a huge amount of wickedly different environments and riding conditions.. The local trails are spectacular specifically Skyline Trail This trail transverses the front ranges peaks giving a world class riding and adventure experience with views to die for. Ogden, specifically, is growing with outdoor specific companies & is creating a community that is extremely active and loves all kinds of adventures. The local amenities have radically changed over the last 20 years with the addition to many top shelf restaurants and small cafes. In down town Ogden you can go rock climbing then Surf a stationary wavy then go indoor skydiving, all in the same building. GCN should come to Ogden and do a series of shows highlighting the marvelous journeys that are available. Great show Boys! I watch GCN religiously. Amen & Cheers - M
Fahrenheit?
Thanks Dr. O and crew....was it hot in there ? Loud and smelly ? I used to work in plastics manufacturing , using injection molds and ultrasonic welds , and it was HAWT !
That's some solid VaultTec (c) autoclave door.
Only mountain and gravel wheels so far. The weights are no lighter than carbon wheels. And those tyre levers are $50.
They didn’t move into bike wheel manufacturing because they are passionate about cycling. They had a board meeting and someone said “did you know we can charge anything we want?”
Nylon-carbon not new story. It's cheaper on labor, more environmentally friendly, but less stiff on same weight, and less heat resistant.
Also its melted in 300 but can be soften at less.
Also it can be more fragile at lower temperatur
Also there is forged carbon, its way of reusing cut off, from carbon fiber sheets
Yeah, it's interesting. I didn't think thermosoft materials would be stiff enough (hence usual use of thermoset materials in lieu of metals).
This factory is really well set up. Way more automated than the facility where I worked.
Really interesting.
Now let’s discuss weights and how deep the wheels can be made. And how wide internal width too - aero gravel please
Super interesting.
Very cool
I’m sure in 10 years they’ll have a even better process 🙌🏻
The machine that works the carbon roll. Looks like the computer from the 1960's TV show, Joe 90. When I saw that machine. I even heard the Joe 90 theme in my head.
So. The day has come, technology have evolve and now we are manufacturing and using rims made of reinforced plastic.
a view points
1) the amount of material needed to be trimed of 4:30 compared to 11:10
2) 8:30 12:30 thr main adantage of thrmoset matrix carbon composit is higher strength. If you want to build realy light, thermoplastics(like nylon or Peek) are not the way to go.
3) 10:50 re heating usually comes with degradation in the Matrix so its not a process you want to do often
4) 11:40 a clean process with thermoset matrix(like the one used by We are on composites) does also need no finishing (you need finishing if you build cheap carbon wheels in asia)
bottom Line: Thermoplastic composites can be cheaper if made in larger quantities (because thecan be produced much farster but at higher tooling cost). They excell at Impacts and are more easily downcycled(recycling is not really a thing(as long as you dont want to make it really complicated/expensive(this is also true for thermoset composites and Aluminium(but to different degrees)). On the other hand you get less strength out of the parts and have to consider operating temperatures.
At 11:20 he bends it with ease with his hands.
For a project i plan to do, i need something really really strong.
I would like to use carbon fibers, but the main problem for me is that it breaks suddenly. Many years ago, i read about some cyclists who said that they prefer good old steel. They said that with steel, they have a warning time. Steel does not suddenly breaks in two. They said steel would rather bend before breaking and give time to the cyclist to react. Sometimes, the cyclist can even spot a crack in the garage before going to ride. With carbon fiber they said, the fork suddenly, without cracks and without warnings breaks in two and throws the cyclist away.
For my next project i need a warning. In case it breaks, i prefer it to rather bend broken than break broken in two peaces.
I can not tell you what my project is. But let say as an example that i want to create exoskeletons.
Put in google images "biceps preacher"
I am totally sure, the client will not follow the instructions where it will be written the limit weight the exoskeleton can lift. I am totally sure the client will try to force my product until it breaks. Putting more and more wight on it.
Now imagine the client puts too much weight on the exoskeleton on the biceps preacher bench. If it breaks suddenly like carbon fiber, it will break the hand of the client in two. If it gives to the client some warning, even if it is two seconds only, he will have time to throw the weight.
Now imagine somebody uses the exoskeleton to lift weight on top of his head. Put in google images - "behind the neck presses"
Not to mention, during an accident, composite materials can enter the wound and the bloodstream and create lot of damage. Something people almost never talk about.
