I've given up on my Hobbit dreams of Mags and got some aluminum spoked rims. My loss is your gain.
I converted the hub from drum to disk and put a Ruckus 200mm rotor on it
It is a heat shrunk press fit, however you could add some exterior tapped set screws like the pulley mod if you wish.
It has brand new SKF sealed bearings 10mm axle size.
It is completely stripped and glass beaded and ready for paint of your choosing
Will let it go for $100 plus shipping.(edited)
