I had asked a question of this sorts a while back when I was fitting a front rack to a 25 yr. Old Miyata touring bike. An Axiom rack would not install correctly due to incorrect placement of the mounting point for the fork eyelet. I ended up with a Roswheel front rack that needed to be modified (drilled out) for a larger bolt then what Roswheel allowed. I could find no standards as to mid fork eyelet placement, the 180 number is a first for me.
