It doesn't have to be 100% French!
I was doing this (very hypothetical) shortlist of carbon tubulars based on price, reviews, weight and looks and the Eastons came second to Zipps either 303 or 404 for racing wheels.
But
a) cost (someone in London can get the Zipps for £840, but still!)
b) impracticality (you don't really want to be riding those wheels in potholed London on the way to Crystal Palace or Hillingdon, plus you have to swap brake pads between wheels as they pick up debris from alloy rims which would damage the carbon). Also all the hassle associated with tubular tires.
But apparently riding on tubulars feels soooo much nicer than on clinchers. Maybe in a year, when the rims of my current wheels wear out ...
