Manufacturing process:
Our Engineering team creates a unique fiber orientation which amplifies the desired riding characteristics for a given rim. And each rim carries its own layup schedule documents which are meticulously by the layup workers, it ensures the accuracy of each rim in the production process.
Our carbon rims are made in one piece molding, each rim is made by one piece long carbon fiber, no wrinkles, to make the strength of rim is the strongest. And we use a unique process to remove the air bladder from the valve hole, so that the rim does not have to be patched like traditional manufacturers use.
100% Quality Inspection:
Carbonal does 100% quality inspection and record in database, each carbon rim is given a unique ID number, which allow us to deliver the highest quality product possible and track every rim to ensure the best after-sale service.
