40 Spokes Spinner Style Front Wheel Hub is machined out of billet aluminum and will give the final touch to old school bobbers and custom choppers using spoke wheels. This chopper part features center fin and side spinners for a very distinctive old school look. This spoke wheel hub is for 8 gauge spokes (diameter 0.157″ or 3.99mm) and was designed for custom bikes that do not need a front brake rotor, since brake rotors cannot be installed on it. This custom part for Harley’s is 5-1/2″ wide (140mm) and comes complete with 3/4″ bearings, inner tube and seals. It looks great combined with our rear Wheel Spinner and Wheel Spinner with Brass Studs.
