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?

35 - tooth was the smallest Campagnolo made. They made 35 through 43, and 50 through 53.

The #0305 Grand Sport 116 mm "chainwheel set" is shown in Catalog. No. 18, circa 1984. It's also shown as part of the #279 "Touring group." It came in your choice of 170 mm arm length :-)

It's no longer shown in No. 18bis, circa 1986.
