The chain on a bike is what connects the pedals to the wheel, allowing you to pedal and make the bike move forwards. The chain is made up of a series of small metal links, which fit together like a puzzle.

Chains are an essential part of drivetrains, but they’re also one of the most vulnerable parts. A chain can stretch or break, and if it falls off, it can damage your bike. There are a few things that can cause a chain to fall off:

Stretched chain

Why does my chain keep falling off my bike? Chains can elongate over time, and if they stretch too much, they can fall off. This is most common on bikes that are ridden frequently, or that are left in humid environments.

Too long chain

This is a similar problem to an elongated chain, but it can also be caused by installing a new chain that is too long. When you install a new chain, you should make sure that it is the same length as the old one, or slightly shorter.

Dirty or dry chain

If your chain is dirty or dry, it can cause the links to bind together, making it more likely to fall off. This is why it’s important to keep your chain clean and lubricated.

Cross chaining

Cross chaining is when you ride with the chain in the innermost or outermost gear, putting it at an extreme angle. This can cause the chain to slip or fall off.

If one of the links in your chain is stiff, it can cause the chain to bind and eventually fall off. This is most likely to happen if you have a damaged or bent link.

Worn cassette cogs/teeth

The teeth (cogs) on your cassette are how the chain engages with the wheel. If they are worn, they can cause the chain to slip or fall off. This is most common on bikes that are ridden frequently, or that have a lot of miles on them.

Cogs teeth is bent

If one or more of the teeth on your cassette is bent, it can cause the chain to slip or fall off. This is most likely to happen if you hit a pothole or rock while riding.

Loose screws/bolts

If any of the screws or bolts on your drivetrain components are loose, it can cause the chain to slip or fall off. This is most likely to happen if you hit a pothole or rock while riding.

Misaligned or damaged derailleur

If your derailleur is misaligned or damaged, it can cause the chain to slip or fall off. This is most likely to happen if you hit a pothole or rock while riding.

Drivetrain parts are incompatible

If you’re using incompatible drivetrain parts (e.g. a 10-speed chain on an 11-speed bike), it can cause the chain to slip or fall off.

Low-quality shifters

Low quality or budget shifters can fail to keep the chain tight, causing it to slip or fall off.

If you’re experiencing any of these problems, it’s important to get them fixed as soon as possible. Otherwise, you could damage your bike or injure yourself.

The shifter is twisted too far

If you twist the shifter too far, it can cause the chain to come off. This is most likely to happen if you’re shifting gears too quickly or if you’re not paying attention to where the chain is.

You hit hard bumps

If you hit a hard bump while riding, it can cause the chain to come off. This is most likely to happen if you’re riding on a rough road or trail.

Next, we will walk you through what you need to do if your bike chain keeps falling off.

Your bike chain falls off at the front

If your chain comes off at the front, you should be able to put it back on without too much trouble. Just line up the teeth on the chain with the teeth on the cog, and push the chain onto the cog. If your chain comes off at the rear, you’ll need to remove the wheel and put the chain back on.

Your bike chain falls off at the rear

If your chain comes off at the rear, you’ll need to remove the wheel and put the chain back on. To do this, first shift the gears so that the chain is in the smallest cog. Then, loosen the bolt that holds the wheel in place and take the wheel out. Next, line up the teeth on the chain with the teeth on the cog and push the chain onto the cog. Finally, put the wheel back on and tighten the bolt.

Make use of your stabiliser system

If your bike has a stabiliser system, you can use it to keep the chain from coming off. To do this, simply engage the stabiliser system before you shift gears. This will keep the chain tight and prevent it from coming off.

If your chain is still falling off?

If your chain is still coming off, even after you’ve tried all of the above, it’s time to take your bike to a mechanic. There could be something wrong with your drivetrain that a professional will need to fix.

F.A.Q Why does my bike chain keep falling off?

Why does my bike chain always come off?

There are a few reasons why your bike chain might be coming off. It could be that your chain is too loose, your cogs are worn, or your derailleur is misaligned.

Why does my chain come off when I pedal hard?

If your chain comes off when you pedal hard, it’s most likely because the chain is too loose.

Why does my chain fall off when I stop pedaling?

It may sound counterintuitive, but if your chain falls off when you stop pedaling, it’s actually a sign that the chain is too tight. When the chain is too tight, it puts strain on the drivetrain components, which can cause them to break or come loose.

How do you stop a chain from dropping?

If you’re having trouble with your chain dropping, there are a few things you can do. First, make sure that the chain is properly lubricated. second, check to see if the chain is too loose or too tight. Finally, if the problem persists, take your bike to a mechanic to have it checked out.
