WB20

Key Features of the WB20:

》1. Forged Carbon Fiber Integrated Shell:

Crafted from lightweight and durable carbon fiber material,

the shell effectively protects the pulley for smooth operation,

ensuring the accuracy of electronic shifting, and reducing

performance impacts caused by shaking. Additionally, the

fully enclosed design prevents dust and debris from

entering, thereby extending the lifespan.

》2. Dynamic Airflow Aerodynamics:

The concave point design of the shell substantially reduces

air friction, lowers drag, thereby enhancing speed and

stability during cycling, improving overall riding

experience smoothness.

》 3. Airfoil Blade Design:

The airfoil blade at the front of the shell ectively

guides airflow, reducing turbulence and wind noise,

making the riding process quieter and more

comfortable.

》4. Optimal Pulley Configuration:

With a 12T upper pulley and a 20T lower pulley, supporting all

industry-standard shifting systems, providing a fast, stable, and

precise riding experience, meeting the demands for optimal inertia.

The pulley material can be chosen from carbon fiber or aluminum

alloy to cater to different color customization needs.

Supports 1x/2x drivetrain configurations (1 1-12-speed compatible).

》5. Richly Colored Front Decorative Plate:

Utilizing premium aluminum alloy CNC work and advanced anodization treatment,

offering a variety of color choices, allowing users to freely showcase their personal style.
