I am afraid all this talk of large or high flange hubs is foreign to me. When British Hub Company introduced their three and one eighth inch flange hubs they referred to them as Continental Racing Hubs, and that is how I always refer to them. I believe that I am right in saying that Chater-Lea flanges were even larger, and Powell the largest of all - but it is too cold for me to go out to the workshop to measure them at the moment.
