I am looking at running a dual disc set up on the front wheel for a project with some custom forks to match.
I am having issues finding a hub that has two for the front wheel, the closest I have come is finding a disc/fixed rear hub and then a disc adaptor for the fixed side, a fixed/fixed track hub and use two adaptors OR a disc front hub and use an "over the top" disc adaptor that uses the spokes to maintain lateral tension (it fits over the top of your flange and acts as a new flange).
Any ideas where I could find a dual disc hub? standards are not a huge issue but =>100mm would be beneficial, would be fitting around a set of custom dual crown (the crowns from a set of 888's) rigids. A larger axle would be a bonus but by no means essential.
