Hi all, I own an 88/89 Peugeot very similar to attached picture.
I am looking to upgrade the seat post and am stuck on size between 25mm and 25.4mm.
I have used calipers to measure internal seat tube diameter which is ranging from 25mm to 25.4mm (and anywhere in-between!) depending on the line I choose.
The current seat post has a caliper measured diameter of 25mm to 25.4mm depending on how far up or down the seat post tube I measure as well.
Any ideas recommendations what size to plump for?
Current seat post requires a small amount of persuasion to go in and and out.
