It definitely depends on your definition of extreme weather. I've been more of a "take the train unless the weather is nice" or "cycle unless the weather is bad" person at various stages/places. So I admit I am biased. In my defense I have been shopping for commuter bikes recently and I don't see any compelling options (actually no options from most brands) compared to 1x10 and 1x12 bikes this year. I've also seen noticeable efficiency loss in my old Nexus 7speed bike compared to others and never considered getting another IGH bike after that one.
