After nearly two months and several test rides, I finally pulled the trigger and bought a 2011 Specialized Secteur Sport. I was sorely tempted to get a Roubaix, but really could not justify spending a lot more when the differences in ride quality are really minimal, IME. I did not like the 25mm "All Condition" stock tires,since they seem a little sluggish, but after a couple of rides I find I'm not really any slower than I was on my Trek 1500. Still, the first modification will be to replace the stock tires with some GP4ks, then I'll see about flipping the stem. LOL I think I can match the ride quality of the Roubaix with the GP4ks.
