Using these Delta cycling cleats is easy. First, make sure they are compatible with your non - KEO LOOK pedals. Attach them to your cycling shoes using the fasteners provided. You can adjust the cleats laterally up to 4mm and longitudinally up to 12mm for a perfect fit. When cycling, to disengage your foot from the pedal, rotate it either towards the outside or inside. Be careful while making these rotations to avoid sudden movements. For maintenance, keep the cleats clean. You can use a mild cleaner and a soft cloth to wipe them. Store them in a dry place when not in use to prevent the polyacetal and PTFE materials from getting damaged. And remember, the memory positioner can help you quickly re - position the cleats if you need to change them.
