Actually, the way I have my touring bike and my tandem set up is half-step plus granny. With an 8
speed cluster the tooth difference between the middle and large chain rings was 3 teeth. This lead
to a shifting pattern of "is it a little change in the pedaling effort = shift the front","is there
a larger change in the pedaling effort= shift the back". This works fine.
