im 6'2, i like 167.5 on fixed, and 172.5 on road...
i had 165s on fixed for a while but it felt a bit short, so i decided to size up, but i was sort of scared of the same cornering problem with pedals and went with 167.5s. they feel perfect on the fixed gear.
i've had 175 on a road bike but that felt a bit much, 172.5 is about the longest i can go and feel comfy.
