In 1987, Campagnolo came out with an indexed shifting system they called 'Syncro'. It didn't work very well, and was generally tempermental. In 1989, they came out with an updated 'Syncro 2' that changed the spring arrangement, and updated to a higher capacity -- a large rear shifter "drum" diameter meant more cable could be taken up, to shift 7 speeds -- and 8 as well
