Obvious that they are clipless, but how do the shoes attach to the pedal?? What other components did HI-E make? It looks like the red bike in the picture has Huret Jubilee derailleurs. Did he ever make shift stuff? I remember a pedal make in the 70's that was very interesting. It was basically a pedal axle, with a needle bearing sleeve tube over the axle. Very simple and light. the cleat was a plastic snap-on clip, and it was extremely light. I can't for the life of me remember who made it, but it was a very ineresting design. Do you know what I am referring to? It seems like you have more experience with bike history than me, and I've never met anyone who knows what pedals I am talking about. Thanks for the info on HI-E. Oh. Where did he produce his components? Did he have a regular factory, or a machine shop where he punched them out one at a time?
