Campy's 3-pin aluminum G.S. crankset seems to have been designed to the old 116 BCD standard, as it perfectly matches a set of Cyclo chainrings.
It has 9mm holes for the chainrings rather than the 10mm standard used today almost everywhere..
Anybody know where short 9mm recessed nuts (track nuts) can be found?
