Explore carbon rim weave options, including UD, braided UD, marble, Hexa-Comb, 3K, 12K, and twill. Learn how weave patterns affect appearance and finish choices.
Details
Rim weave plays an important role in the final look of a carbon wheel. When we talk about rim weave, we’re referring to the outer carbon layer that gives the rim its appearance. Underneath this top layer, we use unidirectional (UD) carbon fibers to optimize the strength-to-weight ratio. In this blog, we’ll walk you through some common rim weaves to help you make a more informed choice for your next rim or wheel project. UD UD is the most common choice for wheel brands. Depending on the rim finish (paint-free or painted), the fibers may or may not be visible. With a paint-free finish, the fibers remain visible without an additional coating. However, UD has a relatively plain, aluminum-like appearance. For brands looking to give their products a more distinctive look, twill weaves and other patterns (3K, 12K, etc.) are often preferred.
Braided UD This weave takes time and patience. UD carbon cloth is cut into narrow strips and wrapped around the rim one strip at a time. As the process involves a lot of handwork, slight variations in the pattern may occur from one rim to another.
Marble This pattern features small pieces of carbon fiber scattered across the rim surface, creating a distinctive, marble-like appearance.
Hexa-Comb This pattern uses carbon cloth with a specific weave design, combining 3K carbon weave with hexagonal shapes to create an elegant look.
3K / 12K (Plain) “K” refers to the number of carbon filaments in a tow, or bundle. 3K means 3,000 carbon filaments per tow. In a plain weave, the carbon tows are woven over and under each other, creating a tight, symmetrical checkerboard pattern, also known as a 1×1 weave.
As the name suggests, 12K uses 12,000 filaments per tow, giving it a bolder, more pronounced appearance than 3K.
3K/12K Twill (Vertical/horizontal) Twill weave features a diagonal pattern, typically at 45°, creating a herringbone-like appearance. Depending on the pattern direction, it can be presented in vertical or horizontal orientations.
Please note that the same weave can look different depending on the rim finish. Some weave options may also incur an extra charge due to additional labor or material sourcing. If you have a specific weave in mind that isn’t listed here, feel free to send us a photo or reference. We’ll check its feasibility for your project.
