On my red bike I had a triple with 7 speed freewheel for 21 gears. That was my cross country bike. I used Shimano stuff from mountain bikes. Rear was 12 to 28 and front was 28, 38,50. The 28 to 28 was useful going over the Big Horn mountains. The red bike is one of 1 of 100 prototype bike Alsop used for testing the concept. Actually frame number 49. They were by a NW USA builder named Paul Barkley. The beams were sold as a kit to retrofit bikes originally but the people who used them said it made the top tube to high to ride comfortably. That is why they made bikes around the beam. If you are old enough Alsop was a plastics company that was famous for making an adapter to use 45 RPM records on a normal record player turn table. Roger
