I have a dual disk Phil Woods Kiss Off hub I'm selling. It is BRAND new has never been ridden on. Was going to use it on my current build but decided to go with a slightly different hub I got built. Once again this is brand new..only been laced to rim but never ridden. This is not your scrappy hub you buy from anyone. It was purposely going to be built to be used for a motorized bike. Is running dual disk. Mount a sprocket on one side and a disk on the other. Both sides are 5mm standard disk rotor pattern. 36hole hub. I spend a little over $500 for this hub but letting go for $400..once again NEVER been used on a working or non working bike on the street or anywhere for that matter. Awesome hub..I understand some may not know who Phil Woods are but if you do you know they are not your typical hub. They make great stuff.
