Congratulations, I own a '98 Zurich with the classic red with white panels on the terrific Reynolds 853 frame and it came with 25mm but I now ride 28mm. You have a 130mm dropout spacing so as said any 8 to 11 speed groupset/wheels will nicely fit. I found the stock 2x9 Shimano Ultegra 6500 groupset flawless but parts always get harder to find with older groupsets.
