So I'm trying to find the value of my bike, but for some reason it doesn't exist on any kind of 'database' (I know I probably shouldn't be looking for a bike value off of them, but it's all I can think of). The frame is aluminum and says all the following: cannondale, sr500, and caad. It's got a carbon fork, shimano 105 rear shifter, shimano tiagra brake levers and I'm pretty sure the rest of the parts are shimano. Someone please hook a brother up. Thanks.
Update: Thanks to @Batman's comment, I found exactly what my bike is. Here it is: http://www.bikepedia.com/quickbike/BikeSpecs.aspx?year=2006&brand=Cannondale&model=Sport+Road+500
