Cyfac Carbon | Custom Carbon Fiber Frames

This video demonstrates Cyfac's carbon stratification process using a combination of Kevlar, Taffeta, 3K and 1K carbon weave. All Cyfac frames are hand-built in the company's Loire Valley factory in the French countryside.

The tubes are preformed in our moulds according to a variety of different specs/criteria for the usage. The black stuff is special epoxy that's mixed with some carbon for tacking purposes and a small amount of structural function. More is put on than what remains once a variety of prep steps happen before the kevler-carbon stratification. So, the weight is really minimal while the integrity and durability is fantastic.

We are using Kevlar for its resistance to cutting/shearing/breakage as well as its unique properties for dealing with vibrations. It ensures a level of structural integrity and resistance to breakage that cannot otherwise be attained.

wow!

This is the MOST detailed video of how to fabricate a Carbon Fibre bike I have ever seen!

thank you for sharing!

No wonder carbon fiber frames are expensive...

@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.

@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.

please correct me if I'm wrong. Most manufacturers have moved away from this 'lug-to-lug' construction, is that correct?

[benkilbee]

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!!

Very interesting carbon fiber porn

The metal bb shell is actually covered with kevler initially...

[edwardsmatt5]

carbon fibers aren't supposed to come in contact with any metals it cause eventual decay.

@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.
