Rim: 1. What carbon weave options does ORNAN offer? UD is standard option. Other carbon weave options, such as 3K, 3K Twill, 12K, 12K Twill, marble and other customized finishes, may also be available depending on the product. Please contact us for specific customization requirements. 2. What surface finishes are available for carbon rims and wheelsets? We offer multiple surface finishes, including matte, glossy and paint-free carbon finishes. Customized gloss levels or special surface treatments can also be discussed for OEM/ODM projects. Note: Minor visual variations or small surface imperfections may appear on paint-free carbon products because no additional paint layer is used to cover the raw carbon surface. 3. Can I customize the decals and logo on the rims or wheelsets? Yes. We provide custom decal and logo services for OEM/ODM customers. Logo size, position, color and graphic design can be customized according to your brand requirements. For specific branding projects, please send us your logo file in vector format if available. 4. Can I customize the rim dimensions? Yes. We offer carbon rims with different depths, internal widths and external widths for road, gravel, MTB, cyclocross and other applications. If an existing mold does not meet your requirements, customized rim development can also be discussed depending on the project volume and technical requirements. 5. What spoke-hole options are available? Common spoke-hole options include 20H, 24H, 28H, 32H and 36H, depending on the rim model and application. Customized drilling may also be available for specific wheel-building requirements. 6. Can the spoke-hole drilling angle be customized for a specific hub? Yes. For OEM wheel projects, we can adjust spoke-hole drilling according to hub flange geometry, spoke count and wheel-building requirements. Correct spoke alignment helps reduce unnecessary side loading between the spoke nipple and rim. 7. What is the difference between symmetric and asymmetric carbon rims? A symmetric rim has the spoke bed centered on the rim profile. An asymmetric rim shifts the spoke bed away from the centerline to reduce the difference in spoke bracing angles between the two sides of the wheel. This can help wheel builders achieve a more balanced spoke-tension relationship. Asymmetric designs are commonly used for MTB and some disc-brake wheel applications. 8. Are ORNAN carbon rims tubeless ready? Many of our road, gravel and MTB carbon rims are designed for tubeless setups. Tubeless compatibility depends on the specific rim model. Compatible tubeless tires, rim tape, valves and sealant are required for a complete tubeless system. Always follow the tire manufacturer's recommendations regarding rim width, tire pressure and hookless compatibility. 9. How do I choose the internal rim width? It mainly depends on brand position and your usage. Wider internal width comes from wider tyre. Wheels: 1. How do I choose the correct rim depth for a road wheelset? Rim dep...
