carbon rims with grooved 3k twill brake track


Features:

  • Offset spoke holes for better triangulation of spoke angles and balance of tensions in a wheel build.
  • Wider rim system offers improved aerodynamics, better handling in crosswinds condition and faster riding.
  • Tubeless ready design, it makes road clincher rims better tubeless setup and better sealing.
  • Super lightweight, rim constructed with premium Toray T700 carbon fiber, best strength to weight ratio with no expense spared.
  • High TG resin temperature 255° brake track, solve the heating problem on the rim brake clincher bicycle wheels.
  • The grooved track helps to evacuate trapped moisture between the brake pad and carbon rim under wet conditions and brings more resistance under dry conditions, so a smaller force needs to be applied to the lever.
  • 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.
