I'm looking for a new pair of Look pedals. All I see they make are the KEO models. Here is my question. I have older Look pedals on all my bikes and also my wife's and my winter bike on the trainer. If I go with a pair of Keo pedals are the older red cleats compatable to the Keo's. I want to be able to use both my road shoes with any of my bikes, ones with older Look pedals and also one with the new Keo pedals.
