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.
Bikes that typically do have chains with master links are BMX bikes and one- or three-speed town bikes with internal gears. You can also identify if your chain should have a master link by measuring the width of the gap between the link plates. If the width is 1/8 inch, your chain should have a master rivet.
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. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same. 4
What can I use instead of a chain tool?
Removing a Chain Link Without Chain Breaker Tool
- A Hammer.
- A thin nail, or something that can hit the chain pin without getting stuck on the chainplates. A 2mm hex wrench can be used as well.
- You will need something that can withstand a beating but has a hole in it for the pin to pass through.
A master link or quick-release link is a roller chain accessory that allows convenient connection and disconnection of a chain without the need for a chain tool. It acts as a set of the chain’s outer plates, so joining two sets of the chain’s inner plate ends.
