What is CONI?
CONI is the Italian national Olympic committee. They produced the CONI manual in the late 70s with the help of top Italian coaches and legendary builders like Cinelli. The manual was long known as cycling's "bible." Most of the training info. contained within is outdated, but the chapters on fit are an excellent guide, because frame geometry has hardly changed at all. They provide charts for working out frame size and stem length, etc. There is also extensive info. on bike design and geometry, and good explanations of why a bike needs to be built to certain parameters.
The fit advice regarding saddle height and setback is more conservative than the Huggi/Genzling-inspired methods, and it does not rely heavily on formulas. As mentioned in the last post, sizing the frame down by 1-2 centimeters would be required for a modern bike with integrated shifters/brakes, since modern hoods often sit higher. The saddle will usually end up being about 16-18 cm above the top tube for a med.-sized frame. Dave Moulton's fit advice also aligns very closely with what CONI recommends.
