This kit replaces the standard 4 bolt to 3 bolt base plate that comes with Speedplay cleats. It gives you a significant increase in cleat positioning possibilities. In comparison to the standard base plate, it provides you with 5mm additional forward positioning, and 14mm of rearward positioning. It's compatible with all Speedplay road cleats X Series, Zero, and Light Action. All mounting hardware is included. Just to make sure we're clear the cleats themselves are not included.Please Note: Due to manufacturer restrictions, we are unable to ship Speedplay products outside the United States.
