How do you loosen a bike chain?
Chains often loosen when a bike does not have a derailleur. Tools: Grab a wrench that will fit your rear axles.
- Loosen your tire. Loosen the bolts that hold your rear tire.
- Pull back the tire. Move the tire back until the chain starts to tighten.
- Find the appropriate tension.
The thing that causes most stiff links is compressing the sideplates too tightly together, a natural result of using a chain tool that presses in the chain pin under great force to install the chain. The safe way to free a stiff link is to use a chain tool and push on both ends of the pin causing the stiff link.
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.
Why does my bike chain skip when I pedal?
Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Shift down into the smallest ring in the rear cassette again, and press your shifter again to see if the bike shifts properly.
When should I tension my bike chain?
The chain should be tight enough that it only allows you to move it up and down about half an inch. If there is no slack in the chain then it is too tight. And if there is too much slack then you need to tighten that chain.
Why is the chain on my bike loose?
Your chain might simply be too old or can stretch over time. When this occurs you need to replace it. Consider that your loose chain also may be due to operator error. Exceeding the recommended gear range for the rear derailleur on your bike may lead to a droopy chain when you ride in these gears.
