...for the ambitious among you, you can Google up an image search for Velo Orange headsets that shows both the more commonly encountered Gran Cru headset and the French threaded ones. I did it a couple of days ago, out of curiosity.
Veo Orange just rebrands and sells stuff that other people make for them (obviously), so they have sold a lot of different sorts of headsets over the years. It's nice to have access to a (relatively) reasonably priced headset that will fit on a French standard bike. But the stack height is a real problem in a lot of applications.
For a cartridge bearing headset, the other one, the Gran Cru, is not badly priced either. I would guess it's gonna get harder and harder to find 1" headsets of good quality, as demand for them continues to decline because it's an old standard. I was crushed when I found out I couldn't buy the 1" Sronglight ones on Ribble (Wiggle ?) any more.
