Filament Winding Techniques for Carbon Wheelsets

Bola, a leading carbon bike rim manufacturer, delves into the filament winding techniques used in the production of high-performance carbon wheelsets. Understanding these techniques is crucial for appreciating the quality and durability of modern carbon bike rims.

What is Filament Winding?

Definition and Process

Filament winding is a manufacturing process used to create composite materials by winding filaments under tension over a rotating mandrel. These filaments, typically made of carbon fiber, are impregnated with resin to form a strong, lightweight structure. This process is ideal for creating high-performance carbon wheelsets due to its precision and strength.

Applications in Carbon Wheelsets

Filament winding is extensively used in the production of carbon wheelsets, particularly for high-end bicycles. The technique allows for the creation of lightweight, durable rims that offer superior performance in terms of strength-to-weight ratio and aerodynamics.

Filament Winding Techniques

Wet Winding

Process Overview

In wet winding, carbon fibers are impregnated with resin during the winding process. The fibers pass through a resin bath before being wound onto the mandrel. This technique ensures thorough resin impregnation, resulting in a strong and cohesive structure.


Wet winding offers excellent control over the resin content and fiber placement, ensuring optimal performance of the finished product. It is particularly suitable for creating complex shapes and high-stress components like carbon wheelsets.

Dry Winding

Process Overview

Dry winding involves winding pre-impregnated carbon fibers (prepregs) onto the mandrel. These prepregs already contain the precise amount of resin required, which simplifies the process and enhances consistency.


Dry winding offers greater control over the manufacturing process, resulting in high-quality, consistent products. This technique reduces the risk of voids and defects, ensuring the structural integrity of the carbon wheelsets.

Computer-Controlled Winding

Process Overview

Advanced filament winding machines use computer-controlled systems to precisely place carbon fibers onto the mandrel. This automation ensures accuracy and repeatability, leading to high-quality and consistent products.


Computer-controlled winding enhances efficiency and precision, making it possible to produce complex and high-performance carbon wheelsets with minimal human error. This technique is integral to Bola's manufacturing process, ensuring top-tier products.
