What do you prefer? I like Look, I have one pair that is 15 yrs old, and still rolling. Only one issue I have ever had with them is they sometimes squeak when they need to be cleaned. I have also tried speedplay, but did not like them, too much float. In addition, the spring wears out in the cleat. I do not know if you can buy just the spring, I have not found it. The cleat is quite expensive to replace. My wife loves them. She has more foot movement when she rides, my foot tends to be pretty straight. I rode Time a time or two; ) and they are similar to Look, but with more moving parts, and more expensive. would like to try Eggbeaters on my mountain bike, anyone have them? Care to review?
