There are many ways to fix a bike chain that keeps falling off. The most common is to use a chain tool, which is a specialized tool that can be used to remove the broken links in the chain.
Some other ways of fixing a bike chain include using lubricant, using an impact wrench, and using a pry bar.
In this article, we will provide you with step-by-step instructions on how to fix a bike chain that keeps falling off.
Why Does A Bike Chain Keep Falling Off?
The reason why a bike chain keeps falling off is that the chain is not tight enough and it allows the chain to slide out of the sprocket. It can also be because the rider uses it incorrectly, which makes it wear out faster than it should.
What Can Make Your Bike Chain Keep Falling Off?
All of us have seen the chain falling off our bikes and it can be annoying. But there are some reasons why your bike chain keeps falling off.
10 Reasons why your bike chain keeps falling off:
- Loose screws on the drivetrain
- Incompatible drivetrain parts
- Chain too stretched
- Worn cog teeth
- Dirty chain
- Bent cogs teeth
- Bad rear derailleur adjusment
- Bad quality shifters
- Stiff chain link
- Hitting hard bumps
1. Loose screws on the drivetrain
Your bike chain keeps falling off because of the loose screws on your drivetrain. It can be fixed by tightening up the screw with a spanner or by replacing it with a new one.
2. Incompatible drivetrain parts
If you have a bike chain that keeps falling off, it could be because of incompatible drivetrain parts. When you use an incompatible drivetrain part on your bike, you will lose some power compared to a standard drivetrain with the same gear ratio. This will make your bike chain fall off more easily.
3. Chain is too stretched
When your bike chain keeps falling off, it is usually because your chain has been stretched too much. Sometimes, the chain of your bike just gets too long and you need to change it.
The problem with a bike chain is that it is constantly getting stretched. It doesn’t matter if you are riding on a flat road or on a mountain. The chain keeps getting stretched and eventually it falls off.
4. Worn cog teeth
There are many reasons why your bike chain keeps falling off. One of them is the worn cog teeth. While cycling, the chain is constantly moving in a circular motion and this causes friction between the teeth of the cog wheel. This friction causes a drop in tension which eventually results in your bike chain falling off.
The reason the cog teeth are worn out is that the chain has been used for a long time. The teeth can’t be changed anymore.
5. Dirty chain
The reason why your bike chain keeps falling off is so that the dirty chain. That’s why it is important to keep it clean so that it will not fall off when you ride your bike.
A dirty chain can also lead to other problems such as overheating and overheating on long rides, which can be dangerous for you and others on your route or even in traffic jams.
6. Bent cogs teeth
The reason your bike chain keeps falling off is that the teeth of the gears are bent. The teeth of the gears are bent because the bike chain is worn out. This is a common problem that has to be solved by replacing the worn-out chain with a new one.
7. Bad rear derailleur adjusment
There are many reasons why your rear derailleur keeps falling off. One of the main reasons is because of the bad rear derailleur adjustment.
A rear derailleur adjustment is a problem that can be solved with a simple adjustment. You may have to adjust your rear derailleur many times over the life of your bike.
Your bike chain will get worn and eventually fall off. This can happen because of the bad rear derailleur adjustment or because of the wear and tear on your chain.
8. Bad quality shifters
The reason your bike chain keeps falling off is the bad-quality shifters. When you are riding your bike, it is important to keep the chain moving smoothly and not get caught in the gears. This happens because of the bad quality shifters.
A good-quality shifter will keep your bike chain in place. Unfortunately, the cheap and nasty ones do not.
9. Stiff chain link
The reason your bike chain keeps falling off is because of the stiff chain link. This causes friction and makes it difficult for us to move our bikes around. So, we need some way of getting rid of this friction so that we can get on and off faster.
In order to solve this problem, we need a solution that would allow us to easily remove the chain without having to take it off. A bike chain link has two parts and when one part is caught in something, it stops moving.
This makes it difficult for us to remove the link from its location and also prevents us from riding on our bikes.
10. Hitting hard bumps
The reason your bike chain keeps falling off is for the hitting hard bumps. When you ride a bike, you can feel the chain getting hit by the bumps. The chain gets stuck and falls off.
This is because of the impact resistance of the chain links, but it also is because of friction and it keeps on slipping. This friction causes the chain to get stuck in between two links and that’s why your bike chain keeps falling off.
If you have any of these problems, follow these steps to fix your bike’s chain:
Steps To Fix A Bike Chain That Keeps Falling Off
You can learn how to fix a bike chain that keeps falling off by following these steps:
- Step 1: Use a bike chain tool
- Step 2: Remove the bolts from your rear derailleur
- Step 3: Back into the hub
- Step 4: Place the bolts
- Step 5: Check your chain
- Step 6: General checking
Step 1: Use a bike chain tool
The first thing you need is a bike chain tool to help you remove the chain set part. This tool can be found at any hardware store or online seller like Amazon or eBay.
There are two types of tools: chain cutters and chain tensioners. A chain tool is a special tool that will help you remove the broken part of the chain set by exerting pressure on it.
A chain tensioner is a basic tool that will help you adjust the tension of your frame’s rear derailleur hub.
Step 2: Remove the bolts from your rear derailleur
Next, remove the bolts from your rear derailleur by carefully inserting the bicycle chain tensioner and pulling gently.
Step 3: Back into the hub
When removing the rear derailleur, make sure it is tight before reinserting it back into the hub.
Step 4: Place the bolts
Now that your rear derailleur is back in place, place a bolt in each of its holes to hold the chainset firmly in place.
Step 5: Check your chain
Once you have tightened the bolts, check to see if the chain is still loose around the rear derailleur hub. If it is not, try another chainring to tighten it.
Step 6: General checking
You should make sure the chain is not too tight or too loose. You should also check for any metal parts of the chain that are protruding or bent.
If this happens, the chain may be too tight and can cause damage to the bike frame or drivetrain components of the bike. It can also cause problems with shifting and braking.
If you’re still struggling with fixing your chain, then you’ll need to go ahead and buy a new one.
Conclusion
The bike chain that keeps falling off is a common problem for many commuters. If you are not careful, it can be a safety issue. The chain should be replaced after a certain number of times.
The bike chain on your bike is one of the most important parts of a bicycle. It is responsible for keeping the wheels turning and moving as you ride. If it gets damaged or defective, you may have to replace it at some point in time.
