The bicycle, itself is not enough to determine value. We also need to know what components are fitted and where you are located(some markets are much stronger than others). When taking pictures, take at least one, square on, from the drive side(this will help us to determine if the frame is bent). The other pictures, clear and close up, should be of crank set, derailleurs, brake levers and calipers, etc...

Hope that is a help.
