The Campagnolo Super Record group on the Gazelle is an 86 model year, though the S.Record group was produce from the mid-late 80's up through around 87 or 88 I believe. The S.Record came to me on the Serotta, but after the paint job on that bike I knew the 10sp Campy was going to look better on it than on the Gazelle. So the switch was done and I couldn't be happier.
