My shoes have a shallow tread and the tread doesn't rest on the spindle. There is probably a space of at least 1mm. So my pedal will unclip when hopping or even cornering. I am hoping these sleeves make up space to keep better tension on the pedals.
Im pretty sure the ones i have are older, but they still fit on the current design (just tried to make sure) . . . . i dont think they body outer diameter changed
