Connex links are great, but no 12 speed model actually seen for sale, despite website info dating back at least 18 months. The problem is there are already many different versions of 12 speed chains and a link that fits an eagle chain will be too loose for the narrowest axs chain. An eagle link works well with a Campy 12 chain. I've reused axs links many times. Just be sure there's some snap left in it, when rejoined.
