Actually, Campy Victory used a 116 BCD circle, in common with Triomphe and the last version of Grand Sport. So selection of rings could be a little l imited. I don't know of any other 5-arm crank besides those three that use d a 116 BCD circle. It was a very common circle for three arm cranks, both alloy and steel, but of course that's of no help in terms of ring selectio n.
