R1B Carbon Rear Hubs
These hubs are manufactured from a high-performance carbon composite material, providing a lightweight upgrade with increased rigidity and reduced flex. The enhanced stiffness delivers a more direct handling feel.
Key Features and Specifications:
- Manufactured using premium TORAYCA® carbon fiber material
- Increased rigidity compared to standard nylon arms
- Reduced flex under high loads for improved handling precision and response
- Lightweight
- Direct bolt-on replacement for standard parts
- Natural Color: Our injection-molded carbon nylon parts retain their natural material color, with no added pigments or colorants to achieve a gray appearance. This approach avoids unnecessary additives that may affect the material’s mechanical properties, allowing us to prioritize the inherent strength, durability, and performance of the base material.
Includes:
- x1 Rear hub, Standard, carbon
- x1 Rear hub, HRC, carbon
- x4 Hub Spacers, 0.50mm, carbon
- x4 Hub Spacers, 1.00mm, carbon
- x1 Hub inserts, 'A', carbon
- x1 Hub inserts, 'B', carbon
- x1 Hub inserts, 'C', carbon
Note: This item includes one of each hub style: Standard and HRC. If you need a pair, you must order two of this item.
Assembly Note:
For screws installed directly into carbon-reinforced nylon, apply a light coat of grease to the screw threads before installation.
