I currently ride a 1981 Trek 61X with a 22.5" frame that is a bit too large for me (5'6"). I would like to acquire a 1982 or 1983 Trek 720 21". However, the brochure on Skip Eckert's excellent sight only shows the frame geometry for a 22.5" frame. Can anyone tell me what the top tupe length is on a 21" frame? Also is the rest of the geometry the same as the 22.5" frame (i.e. the head tube angle, seat tube angle and especially the 47cm seat stays)? Also, I would be interested if anyone has one for sale.
Thank you,
