stronglight headset installation question

I'm trying to learn the peculiarities of French bikes, but I'm not sure I'm ready for all this. I bought an old PX-10 frame that I'm beginning to rehab. I also purchased what I assumed to be the correct headset. Both purchases off eBay. The problem is that I can't figure out how to install the bottom headset race. The inside diameter of the bottom bearing race is stepped. One side down, it seems to fit, but the word "Stronglight" is upside down. If I flip it, the diameter is too big, and it is loose on the fork. The fork seems to have what I believe to be a standard French diameter - 26.4. Am I missing something?

Are you talking about the crown race, the part that goes on the fork? A picture would help.

Yes, I'm talking about the crown race. I'll try to get a picture. I know it would help, I'm just kinda lazy.

I think that I've uploaded the pictures, but I'm not really sure. Hope they help.

I've never installed that particular headset, but the bottom picture (the one with Stronglight upside-down) looks right to me. I'm guessing the bottom head cup covers up that lettering anyway? All the same the lettering seems weird, but hey, it's French.

Are you sure that is installed the right way and this the right bottom race it looks a lot like a top race installed upside down.? This may not help much it is a pic of a vintage Stronglight headset from a bike I no longer own on the bike.

I am sure it's the crown race. I assume that the second (sideways) picture shows the correct installation, but I was surprised by the upside down lettering. Is it possibly made to fit two sizes of forks?

If you flipped it upside down, the cone would no longer point in the right direction.

Just ignore me. I'm an idiot. I just re-read the ebay listing for the headset. It clearly says "27mm crown race". According to Sheldon Brown, the Peugeot should have a 26.4 fork, and that's what I get when I measure it. So, the lettering does go right side up - on a different fork. Sheldon says Italian, although the threading on this headset is French. It's interesting because if the race is installed with the lettering right side up, the bearings ride in a concave groove rather than the traditional cone. Oh well, back to eBay.

The first picture, with the lettering right side up, is the correct way to install it. Looking at it, I can see the groove where the bearings ride. I have a Stronglight competition headset very similar to this and it is installed that way.

One option you could try can't say it will work is to try using what you have and setup up all loose ball no race it's a pain but often a solution.
