Shimano Wedge spacer set SM-SH20

Shimano SM-SH20 plate spacers for SM-SH10/11/12 cleats. Perfect symmetry is rare in nature, and cyclists are no exception. In fact, it's not uncommon for leg lengths to vary. To compensate for this, SHIMANO has developed point stackable cleat spacers that allow height adjustment from 1 to 5 mm.
