Dongguan No. 1 E-Commerce Co., Ltd.

Focusing on the research and development as well as manufacturing of high-performance road bicycle wheelsets, with **lightweight, aerodynamics and rigidity** as the core, we serve competitive cyclists and cycling enthusiasts, and are committed to enhancing cycling efficiency and speed experience.

### **Core Technology Highlights**

1. **Material Innovation**

- **Carbon Fiber Technology**: Utilizing T800/T1000 grade high modulus carbon cloth, combined with hot-pressing molding technology, to achieve the optimal balance of wheel weight and strength.

- **Hybrid Material Wheelsets**: Carbon-aluminum composite rims (such as carbon fiber brake surface + aluminum alloy spoke holes), balancing braking force and durability.

2. **Aerodynamic Design**

- **Optimized Rim Section**: U-shaped/V-shaped/saber-shaped sections, verified by CFD fluid simulation and wind tunnel tests, to reduce side wind interference.

- **Hidden Spoke Caps**: Minimize turbulence and enhance stability during high-speed cruising.

3. **Wheel Structure**

- **Spoke Technology**: Radial/offset rim design, combined with flat spokes like Sapim CX-Ray, to reduce wind resistance.

- **Hub System**: Ceramic bearings (such as CeramicSpeed), 6-pawl engagement mechanism, ensuring instantaneous power transmission.

### **Product Line Coverage**

- **Race-Level**: Ultra-light wheelsets with frame heights under 50mm (e. g., 1250g/pair), ideal for climbing.

- **All-Rounder**: MID-frame height wheelsets ranging from 50-65mm, offering a balance between climbing and flat road performance.

- **Aerodynamic Time Trial**: High-frame height wheelsets of 80mm+, catering to the demands of TT/TRI events.

- **Entry-Level Training**: Aluminum wheelsets, providing a cost-effective and durable option.
