would I be right in thinking that a chainring with a 110mm BCD will have the same overall diameter as a chainring with a 130mm BCD? ie a 53 tooth ring would have the same overall diameter whether 110mm BCD or 130mm BCD. If I need to sit in the corner wearing that lovely conical hat with a "D" on it please let me know. ^_^
 
Yes, unless one of them is a non-round chainring.
