Do all bike chains have a master link? Nope, not all chains have master links. If your bicycle has derailleurs, it means it’s unlikely that your bike’s chain will have a master link.
Do bike chains come apart?
Your bike chain will have outer plates, inner plates, rollers, and pins. You’ll use your chain tool to push the pin out of the rollers, which makes the chain come apart.
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.
If you have a standard chain with no master link: Seat the chain in the chain tool, with the pin of the chain tool aligned with a pin in the chain. Turn the handle of the chain tool until you push the pin out far enough that you can break the chain.
How often should I change my bike chain?
The 2,000-Mile Rule. To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles.

How do I know my bike chain size?
