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.

Have been using Connex links for the past 4 years. However, the price for 12 speed links was cost prohibitive. The price I found on CYCLOWAX was outstanding. This purchase was a no brainer.
