I tend to have poor posture anyway and what I saw in the pics was that I had a little less curve in the back but my arms were more than 90 degrees from my chest, with the Simoncini the arms were about at 90. Every other item, seemed as close as one could tell from a picture. One thing I have notices is a propensity to slide a little forward in the saddle, for a time I compensated for that by a little higher tilt but that caused other problems, So I think if I can get a little better saddle position and a little less stress on my lower back I will be better - maybe not century perfect, but better.
