i'm exploring the best way to mount right now
Thinking that 6 bolt disc mounts on 135mm MTB hubs should all be at the same location relative to the centerline, I bought a schwinn m525, on closeout sale to work with. I'm measuring that now to see how much shimming will be required to align it perfectly with the front sprocket. If my thinking is right it should be the same on every Kings 80 (and others I would hope) and could be transfered to a tery rim later without modification. (after I win one cheap on ebay)
I'll let you guys know if I get it to work well.
