I've heard that some Alex Singer and other French touring bikes came with 4 chainrings, and I know that it is possible to fit 4 chainrings on a TA Pro 5 Vis crank. I'm curious, what chainring sizes were used on the quad cranks, and what freewheels? +++++++ My friend Scott Steketee used quads on both their Jack Taylor and Bill Boston tandems, if I recall correctly. I believe he used a modified "half-step+granny" with 3 half-step cogs and a relatively wide FW.
