Hi folks,
I sent these queries to Eric Elman and John Quigley with whom I have been corresponding re. my PX10E. I got helpful responses but thought that I would also put the queries to the rest of the list - especially the Francophiles.
What have you others found to be the standard diameter of the seat-tube on PX10s or comparable French bikes? I had assumed that it would be 26.4 and each time I measure with the micrometer I get a slightly different measurement. I now think that it is 26.2, in fact. I certainly can't get a 26.4 post in the tube. Does 26.2 seem right? If so is the alloy Simplex post from Bicycle Classics suitable? Are there any others out there that would do - an $80 or $90 dollar period-correct Simplex is not presently on the cards!
