Connex Link 12S (tool-free)

The only reusable 12s Shimano compatible link, works great with my 12s xtr chain cassette. Quality product.

there is no way back after you are used to connex link. all my bikes are equiped with it, also the latested one. Wax and connex link (tool free) mega combination

Connex Links - Great Value Long Term

The design makes it much easier to remove and install the chain making maintenance much easier. I prefer to remove my waxed chains when washing my bike, now there’s not the constant changing and expense of the Shimano links which wear quickly.
