I got a S20 last Thursday as a present from my wife. My LBS upgraded the 105 drive train to full Ultegra 10 (this is one good reason to support your LBS) for free. I am moving up from a Fuji Finest, which was a fine bike (the Fuji held up to my then 290 lb weight and served me well to my current 230 lbs over about 3000 miles). The Scott frame s super light as compared to the Fuji, about 25% lighter. The S20 frame comes with the CR1 form and rear stay, the same carbon as Scott's team issue. After about 70 miles over the weekend, the frame seems to be really stiff and really soaks up the road noise, as compared to the Fuji.
