If you're starting to have problems of any sort with your Look pedals -- accidental disengagement, squeaking, etc -- new cleats are almost always what the doctor will order. How do you wear out cleats? Walking in them is one way, clipping in and out thousands of times through years of stopping at red lights is another.Built from a Polyamide Nylon with co-molded Teflon toe and heel inserts, they'll last longer than the previous generation of Look cleats, they'll engage and disengage with substantially less friction, and they'll be a whole lot quieter as you pedal.One very vital note about Look's Bi-Material cleats: They come in two styles. If you have the Keo pedal system, you must purchase the Keo-specific cleats. If you have any other style of Look pedal -- any model, any year -- you need to choose the Delta cleat. Keo cleats are NOT compatible with any Look pedal system except the Keo. The Delta cleat is compatible with all Look pedals systems except the Keo.The Keo cleats are available in two options: One is the "Red" cleat that allows for 9 degrees of rotational float. The other is the "Grey" cleat that allows for 4.5 degrees of rotational float. You'll get 2 cleats along with all of the hardware to secure them to your shoes.
