The 7 speed era for Trek started in 1988. One complicating factor is that most of their cabron and aluminum bikes in the late 80s and early 90s were not mass produced but made to order. The customer could chose components. Since tubulars were rarely specified with aluminum but often with carbon frames, I suspect that the rims came from a 88-93/94 carbon frame.
The sunrace cassette is not OEM but a later replacement part, so are the hubs. So the only OEM part you have is the rim and this is for an aluminum/carbon bike
