Why deal with 3 different "spider" brackets and support rings that are complicated to assembly and take 45 minutes to attach to the windmill shaft?

Our one piece hub assembly takes out all of the labor and is fully pre-assembled so you don't have to build it. The hub assembly attaches directly to any 1" crankshaft with two set screws and takes just 5 minutes to install.

Significantly less expensive, powder coated for longevity, and much easier installation.
