BulletPoint3 : User can combine clamp or set screw hub with inch, metric, keyed, or keyless bore for a high level of customization. Proprietary hub machining process for smooth interaction between the hub and disk allowing for significantly longer life BulletPoint4 : Made from high strength 2024 aluminum with a black anodized finish for light weight and low inertia. BulletPoint5 : Hardware exceeds DIN 912 12.9 standards for maximum torque capabilities.
