Wouldn't you also need to replace the Campy BB and the front derailleur for a triple? Otherwise, I don't see how the chainrings would be centered properly and get decent shifting on the front. Maybe this older BCD was why Giovanni Battaglin used a triple.

Edit: after reading the above article, the 36T inner ring was added onto a double crankset. Seems they kept the same BB and Q-factor (pedal spacing). Interesting...
