carbon rims with grooved 3k twill brake track


Features:

  • Wide and stable platform for everything from road bike to gravel bike tires.
  • High TG resin temperature 210° 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.
  • U aerodynamic shape makes road tubeless rims lightweight but still stiff, keeping them stable in cross winds condition.
  • 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.
  • 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.
