I remember having 2 Simplex (badged) seatposts, both clearly marked 26.4, yet one would fit perfectly on my 1974 PX-10 the other one would not even go in. Then I tried it on another PX-10 & it went in fine. ( :

Actually a lot of older European bikes used 27.0 mm, which is probably where JIS adopted it from. It would appear the Stronglight HS's are 27.0 and the Peugeot fork is made for 26.4, which is more common today.

But that is not why I write this. I started doing some assembly as I am starting with only a frame. I have two Stronglight competition headsets, one that was on my red Lejeune for many years. I went to install the crown race on the Peugeot and the race spins on the crown. Tried the other one, same result. They are both too big. I tried an Edco on it and did not encounter this. I will probably use the Edco anyway as it is black and will look nicer, but any idea what is going on here? (Other than the Stronglights don't fit properly)
Thanks
