Hello Craig,

SiNGER seatposts diameters (with expansion bolt) from a 1949 tandem: Front: 25.0mm. Rear: 23.8mm. Note, Front has integrated stoker stem.

You could probably have a frame builder/machinist make one for you.

Hope this is useful.

Regards, Dave Martinez Fremont, NorCal the 51st state

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.
