Features:

• Wider 24mm internal width and mid-depth profile offers enough aerodynamic help when riding alone across gravel plains, but not so deep that is hard to control in crosswinds.
  

• Super lightweight, rim constructed with premium Toray T700 & T800 carbon fiber, best strength to weight ratio with no expense spared.
  

• Smooth Wall Tec. No folded prepreg during curing, smooth both inside and outside rim wall to reduce potential quality issues.

• Carbon Strip Reinforcement. Use unique carbon strip to strengthen the spoke tension and stabilize rim structure and reduce the rim weight.

• Impact Resistant Construction. Carbon rims feature a layer of composite material that increases the impact strength and helps distribute energy and shock from impacts to the rim.
  

• Tubeless Ready. Beadlock design makes the rims better tubeless tire setup and better sealing, results a more lightweight carbon wheels for gravel & cyclocross bike.
  

• 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.

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 followed 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.
