In the above link, the F700 for 1995 came in small, medium, large & xlarge sizes (p.51 PDF, p.52 paper catalog).

Then on the next page (p. 52 PDF, p. 53 paper catalog) in the second table for 2.8 series front suspension MTN frames, seat tube sizes are 16.3 in., 19.5 in., 19.5 in., and 21.6 in. for small, medium, large and xlarge respectively.

I was wondering why the seat tube measurements for medium & large are identical, so I looked at other specs. Top tube and wheelbase are greater for the large size vs the medium. So the large has the same seat tube, but the frame is slightly more stretched out.

Hope this helps!
