So if you go to the Specialized site and look at bikes now, the Sirrus no longer shows as you go down through Road, Mountain, Fitness, etc. (It should be under fitness). If you search for Sirrus, you'll find the Sirrus line http://www.specialized.com/us/en/bikes/fitness/sirrus. A few weeks back, there was a new model, I don't remember the name, that was $5000 and had the Ui2 electronic shifting and FACT 10r carbon. That bike was only on the web site for maybe a month or two at the most. Now that bike is gone and the top line model is the Pro with 8r carbon and disk brakes for $3000. Recon where the Ui2 model went???
