Bicycle hub failure

Click on pictures below for larger image.

This road bike hub caused the rear wheel to collapse as 4 spokes pulled out of the hub flange. It was a fatigue failure.

See below for two SEM (scanning electron microscope) images of the failure area.

This SEM image taken close to the spoke holes indicates that the initial crack is fatigue based due to the presence of striations. Also shown is a secondary crack.

Another SEM image showing elsewhere there is ductile failure where the spokes finally pulled out of the reduced ligament of material.
