Shimano cleats spacers for road range spd-sl cleats consisting of 1 unit of 1mm, 2 units of 2mm, 3 screws M5 of 10mm and 3 screws M5 of 13,5mm. Perfect symmetry is rare in nature and it is not uncommon for one leg to be longer than the other. To compensate for such discrepancies, Shimano has developed overlapping crossbar spacers that provide between 1mm and 5mm of height adjustment.
