The earliest Campy catalog I have showing the Ypsilon rims is 1990. However I do not have the previous year catalogs. I CAN say for certain that Ypsilons were not available in '86 or '87. I do believe 1990 was the introduction year for them.
I am not sure if you are also curious about the vintage of the hi-flg hubs. Are you referring to NR style hubs or C-Rec. hubs? Campy C-Record hi-flg hubs were available up to the early '90s. They were just uncommon.

It included a Campagnolo Ypsilon road wheelset with aero Campagnolo rims and high flange record hubs. Curious about their actual age; Seems a bit late for high flanges to have been in vogue. Any ideas about the likely vintage of these?
