Our S Level Series UD carbon spoke wheelsets use a filament winding carbon rim process that reduces the weight of each carbon rim by 10 to 25 percent while maintaining stiffness and strength.

Carbon spokes provide higher stiffness and better fatigue life, aero and light. UD carbon spokes are 30% stiffer than steel spokes and can reach over 500kgf per spoke, carbon spokes are called ST-01.

The optimized U-shaped design profile aerodynamics of the carbon rims will ensure you get the fastest speed possible.

We have 3 levels of carbon wheelsets for you to choose from, S4545, S4967 and S6767 are the ultra-light carbon wheelset series for 2022. Suitable for top racing level, perfect transmission of your power.

FEATURES:

- Filament winding carbon rims process, 10%~25% weight reduction per carbon rims.

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. Filament winding and Aero Carbon Rim Technology

We use filament winding carbon rim process to reduce the weight of each carbon rim by 10 to 25 percent while maintaining stiffness and strength. Rim profiles are specially designed with aero gains and drag reduction in mind. Free coating appearance technology process.

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.

MANUFACTURING PROCESS:

Our carbon fiber rims are formed in one piece, and each rim is made of long carbon fiber without wrinkles, to make the strength of the rim is the strongest. Every component, including the rim serial number, airbag, and carbon fiber prepreg, is collected, inspected, and weighed to confirm that everything has been taken into account.
