According to Sachs, some cyclists try to reduce knee pain by choosing flat pedals over clipless pedals. “Flat pedals allow the most freedom of movement, not restricting potential twisting or shifting of the knees,” he says. That said, Sachs recommends going to a professional bike fitter to find a set of pedals that work for you. “An experienced fitter will be able to adapt your bicycle, your pedals, and the cleats on your shoes to best allow your body to move in a way that is not antagonistic to its natural movement,” he says. “I can’t reinforce this enough: You want to adapt your bike to work with your body, not the other way around.”
