Add the four pins to your initial measurement, and then make note
of which pin you plan to break. Remember, if you’re using a chain
with a master link, like our KMC, you will need to remove an extra
half a link to make room for the connector.
With the chain cut to size now, reroute the chain through the
derailleur pulleys and through the front derailleur if you have one.
Now, with the chain sized appropriately, we’re ready to cut off the
extra links. We’re using a Park CT- 3 tool that’s compatible with
our 11-speed chain.
Master links use two sides that oppose one another and snap
together without the use of tools.
Install the master link by running the pins through the cut pieces
of chain, and then threading the pins through the holes like so.
