How do you remove a master link by hand?
To disconnect this type of link, place one jaw of your pliers on the chain pin, and the other jaw on the open end of the clip. Then squeeze your pliers until the clip pops off. Then you can remove the outer plate and slide out the rest of the link.
How do I find my master link?
To find the master link on your chain, mount your bike in a bike work stand. If you don’t have a work stand, flip the bike over so it rests on its handlebars and saddle. Stand on the drivetrain side of your bike so you’re able to look straight down on the chain.
