I just wanted to bump this thread and see if any shorter riders (5"8" and under) actually go with longer cranks? I find 170mm to work well on my road bike to give me better sprints on the flats and climbs and I like 165mm on my gravel bike where I can do seated climbs at higher cadence. I was thinking of trying 172.5mm or 175mm to get additional torque on my road bike or would I risk more toe strike by doing so? Curious to hear opinions, thanks!
