Look 6007190200 KEO Bi Material Cleat - Grey was made by Look engineers optimizing all of the characteristics of the cleat, and especially the bearing surface. Even though the KEO cleat is smaller, it has a greater platform surface than the Delta cleat. This new cleat format had been developed for the purposes of losing weight on the pedal - cleat assembly while remaining compatible with all shoes on the market. The cleat size therefore was reduced while retaining the three attachment points of the old Delta standard along with the operating kinematic (pivot point located in the front of the cleat). With KEO standard, engagement and disengagement are even easier and more efficient. The memory clip memorizes the exact position of the cleat during cleat replacement.
