I agree that the OP's bike prolly takes 9/16" pedals, but let's be real: there's plenty of one-piece crank bikes outside of France--and very few of these have ever been sold inFrance. Dyna-Drive is quite old and rarely seen anymore, but it still exists and is decidedly non-French. Lastly, there were countless bicycles exported from France, sold the world 'round, with the 14x1mm pedal spindles....
But, yeah, most ppl these days are running 9/16". My stable is running probably half 9/16", half 1/2"....
