Hi Gang,
Here is a tough one, I got a lovely 1930's (original paint) frame with the seat lug broke at the binder bolt area. Did any one make a seat post that used an expansion bolt to tighten the seatpost rather than a binder bolt at the frame? Hopefully that makes sense. I am looking to see if they exist then locate a size.
