Almost ALL carbon production is from Asia if you look at the percentages and the carbon pre-preg, itself, is largely sourced from Japan.
There are companies such as Alpha, Calfee and Parlee in the States, to name a few. The combined production numbers are very small, however, and their prices are on the high side of things. It's pretty good quality, although I do know of one Calfee tandem that cracked and Alpha had a few frame failures that made the interwebz.
In France, there is still some in-house carbon strand / cloth production and outfits like Time and LaPierre pride themselves on manufacturing their own stuff.
I think Cipolini is strictly in-house builds and a couple of the smaller names still do their own layup work.
Even Pinarello sources a lot of their hand work from Asia. Last I read, even the F8 was only partially assembled and then painted in Italy.
All of my Wiliers are made in China. My TREK Emonda was manufactured in China. My Ribble R872 came from China.
Not from Chicago! LOL!
Campagnolo has has their carbon factory in Romania for years.
shimaNO has factories in Japan, China, Taiwan, Malaysia, Singapore, Indonesia and God know's where else. I own Malaysian sourced shimaNO wheels, but my 105 stuff is from shimaNO's oldest factory and that is still located in Japan. My Ultegra stuff is sourced from various countries. Go figure.
Some people buy on price. Some want a boutique 'name'. Some want to ride the exact same thing Froome or Nibali or Dumoulin ride. I just want a frame that fits me perfectly, rides half decently and going to be safe for a couple of years. With product life cycles being what they are most things I buy are pretty well obsolete in 5 years and almost a 'collectible' or ready for the trash in that same time span. That doesn't matter at all to me. It's just the way it is.
The Honda CR-V can be build in Japan, Mexico, Great Britain, China, Canada or Ohio. So...did you just buy a Japanese car? Or one made in Ohio with a higher percentage of U.S.A. sourced parts than the very patriotic Ford F-150 pickup truck?
Yeah. It's complicated. Buyer beware and do your homework prior to plunking down a wad of dead presidents.
But, I digress...
Can I take a page or three to tell you how well my new carbon faux Eyetalyun carbon fiber bike...and you guys know how I spent years here [censored] about how unsafe carbon fiber is and how it gave me a serious head injury!...handles without ever mentioning how various materials actually handle?
