Important

This CAD model is provided as a design and fabrication reference.

While every effort has been made to accurately represent the hub and its important mounting dimensions, you should always verify critical dimensions against the actual hub, bearing, axle, brake rotor, and related components you intend to use before machining or manufacturing finished parts.

In particular, spline geometry, bearing fits, press fits, ABS sensor relationships, and safety-critical dimensions should be physically verified before production. The spline geometry is a estimate of spline count and 1mm module. 

By downloading this file, you are responsible for verifying that your finished design is suitable for its intended application.

Use it, modify it, and build something awesome.
