Jeez people give the guy a break. I may not be the hugest carbon guy either but someone sharing a short video of a custom assembly doesn't deserve to be shit on. Everyone's a critic.
@baralah This is actually "tube-to-tube" construction. It differs from lugs in one important way - there isn't the set angle that lugs dictate so the ability to set custom geometry is unmatched (just like you'd do with a cut and mitered metal frame). Additionally, our construction method here requires the use of carbon stratification at each tube intersection - this gives the chance to change that lay-up in terms of the material, orientation, and amount to "tune" the frame for each rider.
@baralah Most brands have moved to the "buy" instead of "make" approach and don't actually construct their own products at all. Instead, they go to Asian suppliers who have either open-moulds or proprietary moulds which they then use to make the mass-produced varieties of frames in monocoque fashion. Cyfac is largely focused on custom and well-tuned framesets so having someone else make our products doesn't fit this ethos. We control the design, the fabrication, and the finish.
I think you can see the performance of our frames and the satisfaction of our clients to know that Cyfac frames have the highest reputation for quality and durability. If you follow closely, you'll see that Kevlar adds a layer of durability that no other builder is providing.
Interesting to see this process. Can you tell me, how do you prepare the weave so that it doesn't fray to shreds when you lift it off the table or during the brush application ? When i try to do this using such narrow strips of the fabrics inside my molds, the weave will just end up entirely messed up. Is there a trick?
Is a vacuum process done, or is that not necessary? Seems like it may be kind of challenging considering the shape. Just curious if it’s not done or if it’s done in a later step. Just seems like everyone doing structural glassing that is weight dependent does vacuum bagging
so.., why put a kevlar/carbon layer down first, when about all the good it's going to do is add abrasion resistance.. if you want kevlar anywhere surely it'd be on the outside...
Really interesting. So the tubes are preformed carbon fibre? What's the black gooey stuff that's put on the joints before the additional reinforcement is added? Is it simply epoxy glue? Doesn't that add to the weight, or is it special stuff? So many questions!!
nice to see them being built these works of art! I was wondering what kind of glue is to support all the stress! Ascolta Trascrizione foneticaDizionario - Visualizza dizionario dettagliato
Please forgive my ignorance, but may I know why exactly the kevlar strips are used underneath the carbon fibre strips? Could it not be just multiple layers of carbon fibre instead?
i am not sure if the bike can withstand the heavy pressure. The design only use super glue to bind the tubes together and that is not strong enough considering the weight and constant bumps that the bike may ecnounter on the road. It just may split to pieces.
How much weight can a carbon stratified joint support? Is there metal already inside of the joint or was that part just sitting in place being wrapped in carbon fiber?
Someone the track name PLZ that starts 1 min and 20 sec that bassoon sound so totaly french so good jst like the the frames slick and simple but GREAT. Cyfac tell us the track name PLZ.
@nadoeloiskat most handmade bike frames, unless built for pro-teams or collectors (Which can turn a huge profit per bike, $10k-20K per unit) never really turn a huge profit margin for the builder. Added component parts generally can give the builder a profit on markups.
Damn.. now I see why carbon fiber frames cost soooo much more than aluminium :o Sucks however that they don't show all the rest and videos about carbon factory seems non-existant.
I saw a video in which one company actually makes bike by your body size, so they measure your shoulders width hand length etc. like a suit. Does anyone knows the track that starts at 1:22 min :D like it a lot. PLZ tell me the track name :D.
You are putting aluminum bottom bracket in direct contact with the carbon fiber. The plastics reinforced with carbon fibers can induce galvanic corrosion in attached aluminum structure. not a good idea. Wrap a layer of glass over the BB, will ya.
Herion music! Nice work, bet your bike is strong. I might put skim coat of hysol on aluminum bb for a day before layup. I like the kevlar/cf or innegra/cf too. Thanks. Dont pay attention to the dick w/ears that have never worked with cf for years.
Bikes did´nt get cheaper because production was moved to China...So who´s the winner here?.Not the customer for sure.Btw Cannondale are made in Taiwan.Huge differrence!
I ride one. Until you do, you won't get it. They are not like other bikes. It's nearly 5 years old now. And I still can't find anything to compete with it. But yes, the music is shit.
Dude they are definetly not the same!.Taiwan has better skilled workers than what is standard in mainland China.Anyway who profits from all the production moving eastwards??...Not the customers or the enviroment that´s for sure!.
You make carbon fiber stratification looks easy.

I've the same question...
Good job of metal bonding thanks for sharing.
Beautiful!!
Good Work!
Thank You for reply. Do you make MTB frames maybe a video for MTB frames would be nice to see. Custom frames..like a sewn suit. Luxury we all need :)
That is some shotty ass work.

How do materials hold up against impacts on tubing? And how strong are the joins? Could a street bmx frame be made like this?
The metal bb shell is actually covered with kevler initially...
in the epoxy tacking process is that a clear epoxy or is it mixed with other materials too ?

nice to see what looks to be old school building.
I wonder how these frames compare to the asian counter parts.
How do you vacuum bag that crazy angle

I bought bmx have same,guy explain me due tricks jumps slides my frame bottom will be safe and stronger,looks great
I am scared.. what is the point of the kevlar carbon composite. what is the modulus difference between that and your carbon weave?

My kids think i'm playing plant and zombies because the music lmao
what material ar the frame tube?
please correct me if I'm wrong. Most manufacturers have moved away from this 'lug-to-lug' construction, is that correct?
Does not look tuff enough joints right?
0:48 Completed Main Triangle
What type of glue are you tacking the tubes together with?

Hello this is Chef John and Welcome to Food wishes food video recipe...
ahahahahah...
Hm yes...With Lightweights?
I saw a video in which one company actually makes bike by your body size, so they measure your shoulders width hand length etc. like a suit.
Does anyone knows the track that starts at 1:22 min :D like it a lot.
PLZ tell me the track name :D.

Lightweight went out of business?

I now know why carbon frames break at the lugs ! They are held together with black paint ...lol
Do you build motorcycle frames?
La Vita è Bella - Il Gioco Di Giosue
Wow this is the reason why carbon fiber frames are too expensive
You certainly aren't talking about Cyfac!
fighter planes use the same materials for their construction.
Herion music! Nice work, bet your bike is strong. I might put skim coat of hysol on aluminum bb for a day before layup. I like the kevlar/cf or innegra/cf too. Thanks. Dont pay attention to the dick w/ears that have never worked with cf for years.
Any Redlettermedia fans out there?
Why not lose the ANNOYING music and describe what you are doing in the video?
People are here to learn, not get some tunes...
carefull what you wish for.. he's french remember... you want to hear a french guy speak english?? bweheheh
Why don't you mute the video though
ok . . . la vita e bella
Epic comment. ; )
Bikes did´nt get cheaper because production was moved to China...So who´s the winner here?.Not the customer for sure.Btw Cannondale are made in Taiwan.Huge differrence!
Would you like carbon fibre wth that resin 😂
Thats innegra and twill. Thanks
No, currently we don't. But, maybe we could! Contact esakalowsky@cyfac-expert.fr and maybe we can help.
No wonder carbon fiber frames are expensive...

I ride one. Until you do, you won't get it. They are not like other bikes. It's nearly 5 years old now. And I still can't find anything to compete with it. But yes, the music is shit.
Thank me later.
Doesn't it need to be cook and pressurized ? Thats not how real bike are made !
Dude they are definetly not the same!.Taiwan has better skilled workers than what is standard in mainland China.Anyway who profits from all the production moving eastwards??...Not the customers or the enviroment that´s for sure!.
yikes
This video only shows why carbon fiber frames are more expensive than others
Give a brake. High Tech with a brush and hand lay up. What a lier.
wtf?its road bike? bull shit ,i want to see mtb carbon frame making!
Man this guys suck at making bikes, chinese/taiwanese must be laughing for timed consumed
carbon fiber sucks, the cheapest material to manufacture
