Handmade AVL: The Making of a Boost 148 Hub

All Industry Nine hubs begin with 7075t6 aluminum bar stock as shown above and is then cut into smaller slugs as shown below.

The centers of the slugs are then bored out by a lathe which is shown above. During this process the bearing bores are also created. The bored out slugs are then put back into the lathe, this time being grabbed from the inside of the slug instead of the outside. This is when the flange and rotor mount profiling start to take shape.

Endcaps and axles are also created in the lathe. The lathe below is a special made in house bar feed lathe.

A wire EDM machine is used to cut the drive ring and pawls for the hub.

A mill with a 14 tool turret is used to add the final details to the hub shells such as flange holes and rotor mounts. The mill also finishes the freehub bodies.

Even our seals are made in house using the press shown above.

Polishing the hubs is the final step before the anodizing process

Once the hub shells are thoroughly polished, they are sent over to be anodized.

The final touch on the hubshell is the laser etching of our Industry Nine logos. After this the hubshells are assembled with the axle, bearings, and freehub.
