Regina - I just read Kali's excellent post too, and it might be good for you to get a full fit on that Serrotta fitcycle AND on your Seven at that LBS in Frederick. The fitter there can probably tell you if any adjustments can be made, and/or if you really might benefit from a custom frame. For me, the issue is that I can't get positioned properly on my current bike relative to the pedals - raising the seat just takes me further away from the pedals, and moving the saddle back makes the saddle too bouncy, and makes the backs of my knees hurt. So none of the adjustable points will address the biomechanics properly. Once we had the numbers from the fit cycle, we could compare to my current bike and realy see the differences. It was very interesting to see.
