Ive been dealing with knee pain from a small non-cycling sports injury. I remember hearing that clip less pedals sometimes have float that allows a few degrees of horizontal foot rotation while pedaling, and that’s supposed to prevent twisting of the knees. I couldn’t be bothered with clipless but I still wanted to see if allowing my foot to rotate on the pedal would reduce strain on my knee.
Anywho, I made this contraption. Two plates connected by ball bearings, one plate fixed to the pedal and the other left free-spinning to allow the foot unlimited rotation. It’s mirrored on each side of both pedals. The bearings are called “lazy susan bearings” on Amazon.
I tried riding it and honestly it feels kinda interesting. I feel the plates rotating back and forth as I pedal, which could mean that my feet were missing that rotation before and just torquing the knee.
I might post an update if my knees implode or gain super strength or something. Just felt like sharing
