I just recently purchased a 2015 Specialized Sirrus.
My main reason was for fitness. Although I like to ride fast, I know this bike is limiting. I can currently keep around a 19MPH average on a 20 mile ride which isn't bad. But, after competing in my first triathlon a week ago and another one next week, I know my equipment can cost a couple of miles per hour over more expensive road bikes. And that was my second reason - economics. I just don't have a grand or more to spend on a speedy road bike.
