Which pivot shoe do I need?

When locating a replacement pivot shoe, the most important factors you want to pay attention to are the width, the thickness, and the height of the pivot shoe. The cam doesn't really play an important factor in locating replacement shoes. Your best option would be to compare each of these pivot shoes to yours to see which of the two would make the better match. If you should need any further help, you can upload a couple of photos of your pivot shoe and we can offer our advisement on a replacement.
