Stronglight sizes are baffling. Why 23.35mm for crank extractor threads? Why 38.1mm (which is exactly 1 1/2"!) or 37.8mm for fixed cups? (And my caliper sez that the one on my Gitane is more like 36.8mm.) Why the heck didn't they specify even millimeter (or even half mm) instead of these oddball measurements?
