Does anyone know what the smallest ring made for the Campy 116 BCD bolt circle was? This was used on slightly off-topic Victory and Triomphe, but also on some Grand Sport cranks, which may have been on topic. I believe there may have been a triple version of the 116 BCD Grand Sport. Working out the geometry, and guessing at the distance between chainring bolts, I estimate that this circle should take as small as 34T, but I don't think I've seen these rings smaller than 36T. Anyone know if 34T was made? Does anyone know the date of introduction of the 116 BCD Grand Sport?
