Not at all. Many of us ride MTB pedals/shoes on our road bikes for multi-sided clip-in, better walkability of the shoes, and the ability to run one pedal/cleat system across all bikes. Search the archives and you'll find many discussions of this. SPD-SLs aren't my favorite pedal system, but if it works for you, that's what's important.fisherman said:Alright, newbie here - to the roading scene at least.
I am currently using Shimano SPD M747s, and M959s on my cross/roadbike, cannibalised from my mountainbikes.
Am I missing out by using these instead of SPD-Rs?
