Can anyone help me with the size of the older model single Speed Electra Rat Rod seat post? I have a Seat post mounted rear rack that I am trying to use on it. It is one that bolts around the seat post. The Seat post on the Rat Rod is too small, and the shims that came with it are barley too big. I figure I can use a seat post shim in its place, but I am not sure what size. Nor am I sure what size the ones are that came with the rack. Any help would be greatly appreciated. Thank you.
