Shimano - Spd Schuhplatten - The cleat is the link between the shoe and the pedal. SHIMANO pedals and plates are designed to function in a system network and are optimally coordinated to ensure safe and efficient power transmission. Plates can wear out, especially when walking or during intensive use. They should then be replaced in a timely manner to ensure safe, reliable operation of the binding system. The triggering mode differs depending on the cleat used.
