To fix a broken or bent chain, you will need to remove it from your bike AND remove the broken or bent links. To do that, you will need a chain breaker tool. In the video, we used the Park Tool Master Chain Tool, which is the best tool for the job.
What causes a bicycle chain to snap?
Mountain bike chains break because of wear and tear, poor maintenance, and gear shifting under a heavy load. Others reasons are because of worn cogs, the chain gets hit, and chain suck. Lastly the teeth of the chainring is bent, not using proper joining pins, and not properly installing the bike chain.
What causes bike chains to snap?
Chains break for a host of reasons, but most common is wear. For example, if a chain has been ridden for 2500 miles, it will actually stretch out. Correspondingly, a ridden chain will be longer from link to link than a new chain. Combine all those factors, mix in one bad shift and you have a recipe for a broken chain.
In order to shorten the link without a chain tool, you need an alternative tool like a hammer, pliers or thin nail. They will assist you in pushing the pin easily. You can position the chain over a socket, and hit it with a hammer. Then, you can now pass the bolt all throughout the open holes.
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. Such master links may or may not be re-usable.
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.
How do you break a thin chain?
To cut small chains, such as necklace chains, you need small pliers that can cut through metal. These are often called “nippers,” or wire cutters. Small pliers such as this can be found at any home improvement or craft supply store. If you are just cutting chain one time, use whatever small pliers you have.
