My heavier '99 Trek 2100 has a 3x8 and works well for trailers and hills.
Same for my heavier trikes, going to 30 gear inch lows.
My much lighter bike a Giant TCR does surprisingly well on hills with a standard double 2x9 at 42 gear inches.
I have older legs and close road style ratios are important. and a granny gear is appreciated
