A CroMor framed bike with 105 may not bring as much as you like. Pics and location will help determine the value. Look at some of the post over in the regular section to get an idea of what types of pics to post. (one pic of the bike from 50ft is pretty useless)
You didn't ride it much but the original wheels were breaking spokes? Sounds like you rode it more than you think or you have some really lousy wheels.
