Road vs MTB clipless pedals - why different style cleat
Why the differences in style clipless pedals in road bikes vs MTB? Do the larger cleat for the road bike style offer better performance or comfort for road bike use? I know the road show has a much stiffer sole on the shoe. Does that stiff sole drive a different cleat?
I currently use a Shimano SPD MTB style shoe and clip on my road bike because the MTB shoe is easier to walk in when I am off the bike. I am getting ready to get new shoes (and pedals?) so I am curious about the reasons for the differences.
