How to Fix a Bike Chain That Keeps Falling Off

Summary: If your bike chain keeps falling off, there are a few things you can do to fix the problem. First, make sure the bike is properly tightened–a loose chain will cause it to fall off. Next, try using a link tool to tighten the individual links of the chain. If that doesn’t work, you may need to replace the chain.

8 Common Reasons That Can Make Your Bike Chain Keep Falling Off

1. Stretched Chain

The chain on a bike can stretch over time and with rough use. This can cause the chain to fall off the sprockets. To fix this problem, you can replace the chain or adjust the rear derailleur.

2. Incorrect Chain Length

If your bike’s chain keeps falling off, make sure it’s not too long or too short for the bike’s sprockets. If it isn’t, detach the chain and shorten or lengthen it by moving the rear derailleur.

3. Worn Sprocket Teeth

If the teeth of your sprockets are worn down, then it will be harder for them to grip onto the chain, thus resulting in a slipping-off situation while you’re trying to pedal. In this case, replace your sprockets or add new ones if they’re already worn out.

4. New Chain and Worn Sprockets

If you have a new chain, your old sprockets might not work well with it and the chain could come off while riding. To fix this, you can get new sprockets or add some on to your old ones so they work with the new chain.

5. A Bent Rear Derailleur

If the rear derailleur is bent or broken, it won’t be able to shift gears properly. This could change the length of the chain. If this happens, you’ll need to replace the rear derailleur so you can adjust its length as needed.

6. Bad Quality Shifters

If the shifters are low-quality or poorly constructed, they might not be able to do their shifting job properly, making the chain either come off or become too short. So before buying new shifters, make sure that your old ones are in good shape. If they aren’t, get rid of them and buy some high-quality ones.

7. Chain Rubbing on The Derailleur Cage

If the chain keeps hitting the rear derailleur, it might cause it to bend, which can make your shifting job difficult and will cause your chain to come off while you’re riding. If this happens, try filing down your derailleur cage slightly or replacing it entirely to fix this problem. What if my rear derailleur is bent?

If your rear derailleur is bent, it will likely need to be replaced. You can take it to a bike shop to have this done, or you can do it yourself if you’re feeling confident.

8. Hitting Hard Bumps

If you encounter a lot of bumps or sudden jolts while riding, your chain might come off because it doesn’t have time to mesh together with the sprockets correctly. Try going over small bumps slower and avoiding big ones altogether to fix this problem.

10 Easy Ways on How to Fix a Bike Chain That Keeps Falling Off

If the Link of your bike chain keeps popping open and you can see that it’s because there is a lack of lubrication, use some lubricant to fix the problem. Apply the lubricant to both sides of the inside of the Link and wait for around 10 minutes before riding again.

If your bike chain keeps falling off due to rust, you will need to use oil to fix it. First, clean the rusty Link using a rag and then apply some oil to both sides of the inside of the Link before putting it back together. Now you can ride again without having any more problems with your bike chain popping open.

3. Loosen and Tighten Your Chain

If you notice that your bike chain is too tight, it will continue to fall off as it’ll be unable to stretch. Loosen your chain on both sides of the Link before putting it back together to fix this problem. Now you can ride your bike without having any problems with your chain popping open again.

4. Use a Screwdriver to Align the Chain

If you see that one side of your bicycle chain is not properly aligned, it will fall off easily when in motion. To fix this problem, you need to use a screwdriver to align the sides of both sides of the Link. Now you can ride your bike without having any problems with your chain popping open again

5. Use a Zip Tie

If there is no rust and the lubricant isn’t working, then you might need to use a zip tie to fix it. First, pull the chain so that each side of the Link can be properly aligned, and then use a zip tie to hold them in place before riding again.

6. Use a Bungee Cord

If you need something flexible that can fit any bike, you will need to use a bungee cord. First, pull the chain so that it’s tight enough, and then wrap the bungee cord around both sides of the Link before riding again.

7. Use an Allen Wrench

If you need something that can fix the problem fast, you will need to use an Allen wrench. Push it up and down until both sides of the Link can be properly aligned and tighten them with a wrench. Now you can ride your bike again without having any problems with your chain popping off.

8. Use a Chain Tool

If you need something that can be applied to any chain, you will need to use a chain tool. Place it in the Link while making sure that both sides of the Link are properly aligned, and pull it out while making sure the chain doesn’t get twisted. Now you can ride your bike again without having any problems with your chain popping off.

9. Remove the Old Chain

If you need to replace all the parts of the old chain, remove it and attach a new one instead so that there are no more problems with your chain popping off. This is a good idea if you want to fix the problem quickly.

10. Remove the Chain Pin Completely

If you are not satisfied with just removing the old chain, you should remove the pin completely to be attached to a new one before riding again. Then, you will have no more problems with your bike chain popping off again.

Some Helpful Tips to Prevent Bike Chain from Keep Falling Off

1. Clean your bike chain regularly. Cleaning the dirt and dust on your bike chain will prevent it from wearing down the teeth on the front and rear sprockets, thus preventing it from falling off.

2. Keep your bike in good working condition. If you have not oiled or greased your bicycle in a while, this would be a perfect time to do so.

3. Keep your bike chain clean and lubricated. Cleaning the dirt off your bicycle chain will work more efficiently, thus preventing it from falling off during rides. However, constant cleaning might wear down the teeth of your front and rear sprockets. To prevent this, lubricate your bike chain every time you clean it.

4. Remove the dirt from the links of your bike chain. The best way to do this is by removing the tire off your bike and shaking or beating it with a rubber mallet until all the links are as loose as possible. Now, carefully remove the dirt and dust from the links with a small brush and clean it with water right after.

5. Use WD-40 to lubricate your bike chain. If there is no time to oil your bike chain every day, WD-40 will work fine. Even if it’s a little too thin, an oil spray will still make your bike chain run smoothly and prevent it from falling off during rides.

6. Clean, lubricate, and tighten the bolts on your bicycle before riding again. Remember to clean, lubricate and tighten the bolts on your bicycle every time you oil or grease them. You will prevent your bike chain from falling off during rides if you do this often.

7. Fixing the problem immediately is usually better than fixing it later. If by any chance, your bicycle chain falls off while riding, never try to fix it on the road. It might become dangerous for both you and other passers-by. Fixing it right away usually saves time, money, and energy.

Frequently Asked Questions

Why Does Bike Chain Keep Falling Off?

Chain tension is key when it comes to bike security. When the chain stays tight on the wheel, it’s less likely for it to fall off. One common cause of chain slipping and falling off your bike is the incorrect to use of a bicycle lock. Make sure that your lock fits properly (it should be snug but not too tight) and make sure that you keep the key detached from the lock at all times. You can also install a bolt cutter or special tool to cut through cable ties easily in case of an emergency.

Is It Normal for a Bike Chain to Fall Off?

Yes, it’s definitely not normal for a bike chain to fall off. In fact, this is one of the most common bike chain problems that cyclists face. Bike chains are designed to keep your bike moving, and when they start to wear down, they can become loose. This can cause your bike to fall off, which is unsafe and definitely not something you want to experience.

There are a few things you can do to prevent this from happening. First, make sure that your bike chain is properly lubricated. Second, be sure to keep your bike chain in good condition by regularly checking it for wear and replacing it as needed. And finally, make sure that you always use the right size chain – too big of a chain can cause your bike to fall off, while a small chain can become too tight and cause problems as well.

Do You Tighten a Bike Chain With a Derailleur?

No, you don’t need to tighten the bike chain with a derailleur. The job of the derailleur is to transfer power from your pedaling motion to the gears on your bicycle, and it does not have any control over how tight or lose the chain is. If you are having trouble putting up hills or struggling with shifting in difficult terrain, it might be helpful to adjust your chain tension.

When I Stop Pedaling the Chain Goes Slack?

The answer remains the same: it depends on your bike. Most bikes have a slackening reaction when you stop pedaling, but it can also vary depending on the type of gear system that is installed. So if you’re not sure how your bike works, it’s best to consult with a professional bicycle mechanic.

What Lube Should I Use on My Bike Chain?

The lube you use on your bike chain will depend on a lot of factors, including the type of chain you’re using and the terrain you’re riding on. However, some general tips that may be useful include using a light lubricant that’s safe for your bike chain and gear and applying it regularly to keep them in good condition.

Conclusion

A bike chain that keeps falling off is a common problem, but it can be easily fixed. In this post, we’ll show you how to fix a bike chain that falls off often. The most common cause of a bike chain coming off is that the chainrings and cassette are not properly aligned. Another reason your chain might keep coming off is if the derailleur or hanger are bent. 

If your bike has vertical dropouts, the tension on the chain can also affect whether or not it stays on the gears. To fix a bike chain that keeps falling off, you’ll need to adjust the alignment of the cassette and chainrings, straighten any bent parts, and adjust the tension on the chain.
