I'm having trouble replacing the seatpost in the above frame.
It looks like the seatpost that was in there was too small so the seat-tube and seatpost oval/misshapen - measurements range from 25.9 to 27.1mm.
I bought a 26.8seatpost - didnt fit (I was told the size was likely for the age & tubing?)
Now bought a 26.6, which goes in about 2cm but then gets very, very tight (almost impossible to move by hand).
I've done lots of waggling around with the old post to try and get the seat tube round again. I can't tell if if it doesnt fit and i need a 26.4 or if its just ridiculously tight from being misshapen.
Does know anything about likely sizes for Claud butlers at the time?
Or have any experience/advice getting steel seat tubes round again?
Thanks in advance.
