  • Super lightweight, rim constructed with premium Toray T700 & T800 carbon fiber, best strength to weight ratio with no expense spared.
  • Asymmetric 2.5mm offset rim profile, balance the spoke tension between the drive and non-drive side.
  • Carbon Strip Reinforcement. Use unique carbon strip to strengthen the spoke tension and stabilize rim structure and reduce the rim weight.
  • Smooth Wall Tec. No folded prepreg during curing, smooth both inside and outside rim wall to reduce potential quality issues.
  • Angled spoke holes allows the nipple to pull straight in line with the spoke for reduced stress, this results in fewer broken spokes and nipples.

Unique 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.
