If this is an investment you are sure you are going to use then plan a budget and look at everything. Ride as many bikes as you can, even ones out of your price range to get a feel for what fits and what you like. The more you can spend the better the bike and the less likely you will be six months from now having/wanting to upgrade. I made the mistake of buying a cheap starter bike, and later buying the one that I really wanted. The cool thing about now is the new 09 bikes are coming in and you may find a great deal. Keep in mind you need a helmet, shoes, pedals, water bottles, etc. so factor that in. I personally have a carbon Specialized (roubaix comp). My husband also rides a Specialized. This is a great site to learn from as well as www.roadbikereview.com. There you can actually look up different bikes in their reviews. Good luck and keep us posted on the new ride.
