Allen I'd just read your post yesterday and then went for a short test ride on a bike with a front disc brake adapter of a style that I'd not tried before & it jumped out of line, fortunately I was almost home and going maybe 5 mph at the time so no harm but I was very fortunate, no damage and no injury.. I'll use this one for a pattern & build one that will work. All disc adapters aren't bad, but some are...also some forks aren't great candidates for most, stock adapters. Take caution if it looks funky it probably is...first comes pride (not summer) then the fall (ouch), lol...
