front pulley wheel: high strength aluminum alloy
Crank: high strength aluminum alloy

Key Features:

Pulley Wheel:

Material & Finish: The pulley wheel is crafted from high-quality materials and features a full CNC (Computer Numerical Control) machining process, ensuring precision and durability. It is then finished with a sandblasted anodized surface, which not only looks sleek but also enhances resistance to wear and corrosion.
Crank Arms:

Manufacturing Process: The crank arms are made through a cold forging process, which strengthens the material and improves the overall durability of the crank set. Specialized machinery is used for further processing to ensure the highest standards of quality and performance.
Finish: Like the pulley wheel, the crank arms also undergo a sandblasted anodizing process, providing a uniform and attractive finish that is resistant to the elements.

Benefits:

Belt Drive System: Our bicycle crank sets are designed for use with a belt drive system, which offers several advantages over traditional chain-driven systems.
Quiet Operation: Say goodbye to the noise of a traditional chain. The belt drive system operates quietly, providing a more pleasant riding experience.
No Grease or Oil: The belt drive system eliminates the need for regular greasing or oiling, reducing maintenance and keeping your bike cleaner.
Low Maintenance: With fewer moving parts and no chain to stretch or replace, the belt drive system requires less maintenance, saving you time and effort.
High Efficiency: The belt drive system offers high transmission efficiency, ensuring that more of your pedaling power is transferred to the wheels, resulting in better performance.
