I saw my mate riding on these wheels he bought from a company called https://carbonbikeshop.myshopify.com/ he said he's had them a while but Im always a bit wary about these companies does anyone know any info about them? Thanks.
Shopify seems a Chiness online shop, not sure. Sorry I only know a little about it.
But I bought a wheel set from a company. It's great, not sure the country of origin, too.
If it's well, I don't care the country of origin.
The answer to the OP is no, all carbon wheels are not Chinese. Most are made in Asia though. Some are really good, some are really dangerous, and a lot in between...the gamble is yours. Also, why do you want carbon? If lighter weight is your number one reason, most of the less expensive carbon rims aren't lighter than AL.
