Good idea Harvey. I totally forgot about this option. According to Hadland the drivers should be interchangeable because most of these clones were made by Sturmey. But first I think I'll try Mark's route, only because I want to play around with spinning on two 3/32" cogs and turning it into a six speed with derailleur. If that doesn't work I'll try the same thing with a regular driver. I may need to lower the gears a bit. A friend and I are going to put on our own private Lake Pepin-style-English-gentlemen's-tour here in Arizona. It's going to be a multi-day Saloon Crawl thru such Old West towns as Tombstone and Bisbee (where we'll spend a day with Ken Wallace whether he likes it or not). English bikes, saddlebags, hubgears, but no Tweed. You'd either sweat to death or get shot by some drunken cowpoke.
