Re:
Found this on Sheldon......
"Campagnolo's first attempt at indexed shifting, "Synchro" was designed to work with older Campagnolo derailers, but the cable travel was too short and cable tension too high for reliable indexing. In the early 1990s, Campagnolo abandoned the Synchro system and redesigned everything around a longer cable travel. I don't know the exact year of this change, but I believe it happened at the same time as the move from 7-speed to 8-speed."
So it really depends on what you've got.
