Sean,
The Simplex mounting bolts have a 9mm shoulder that fits inside the threaded 10mm hole in Campy and similar style dropouts.

My question is that a campy dropout hole is much larger in diameter than a simplex. Will this pose a problem, or will the torque be enough to keep it in place? Should I use some sort of spacer or something? Any suggestions would be much appreciated.
