My wife and I came across a Trek 1200 for cheap. She is new to the roadie scene and I am not a pro at sizing. It looks a tad small but not sure how to tell. With the seat up fairly high, she has a slight bend in her knee at the down stroke. She complains about her head being to far down. I do not know if this is so bad, but she might have a point. Should her head be closer to level with her butt? We are thinking on going to the bike shop today and having them check the size out.

Measure the vertical height of the saddle above the top tube, near the nose of the saddle. Anything over 17cm (6-3/4") will make it difficult to get the handlebars up to the desired height for a beginner.

Also measure the height difference from the floor to the top of the saddle and the top of the handlebars. A beginner may want this difference to be only 1-3 inches and even experienced riders rarely exceed 4 inches.

These tests only verify the vertical size of the frame. The correct top tube length and stem length is more complicated.
