TECHNOLOGY

1. 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.

2. 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.

3. Fast Tire Installation

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

4. 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.

5. 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.
