Much like buying real estate, buying a bike involves 3 things. Fit, Fit and Fit. Make sure you go to a reputable LBS that is known for customer service on ALL bikes, not just high end ones. My first bike wasn't fitted properly and it caused a few problems, including buying a second bike about a year later.
I have a friend who started out with
this bike and has been super pleased with it, but remember to test ride and get a proper fit...bikes are like jeans, there may be only one or two pair that REALLY fit right
