I've forgotten what other shifting patterns were popular. I do recall
that "alpine" came only on department-store bikes, and "half-step"
used two chainrings that differed by half as much as the cogs. I
suppose half-step might achieve a granny gear by adding a wee third
ring.
That "half step plus granny" was very popular on touring bikes back in
the days of five or six rear cogs. It's still being used on three of my
bikes.
