TECHNOLOGY


1. High TG 255°C Brake Surface

High TG resin temperature 255° brake track, solve the heating problem on the rim brake clincher bicycle wheels.


2. Tubeless Compatible Technology

The bump on the rim bed helps to create a buffer during tire inflation, making the mounting process easier. The bead locks allow for an easy switch between clinchers and tubeless setup.


3. Ultra Smooth Inner Wall

Use specific, thinner, high-pressure air bladders to control the inner wall smoothness, The result is that we could see a very clean and smooth inner wall, which means the carbon fabrics are stretched smoothly and optimized. This could ensure the best strength of the fabrics.


4. Fast Tire Installation

Easy installation and removal of normal tube tires and tubeless tires.


5. Double Wall Design and Aero Technology

We use a double wall design to better control the rim strength and stiffness during layup. Rim profiles are specially designed with aero gains and drag reduction in mind.


6. Customized Spoke Hole Angle Drilling Technology

High-speed CNC machine tools drill carbon fiber rim spoke holes. Customized according to the geometric angle of the hub. Check all drill holes to make sure they are free of burrs.




CARBON 700C RIM BRAKE WITH 5 BRAKING SURFACES OPTIONAL



We have 5 braking surface systems for professional cyclists to choose from. The high TG resin temperature of the 255° brake track solves the heating problem on the bicycle wheel of the rim brake. 

If you have special requirements for the brake system, Grooved 3K twill will be your best choice. 

The grooved track helps to evacuate trapped moisture between the brake pad and carbon rim under wet. it bears a higher temperature while braking, but for faster braking heat elimination. More friction, less lever force needed, and shorten about 30% braking distance. More friction to shorten the braking distance.
