How to Put a Chain Back on a Bike: And Why It’s Like Solving a Puzzle While Riding a Unicycle

Putting a chain back on a bike might seem like a straightforward task, but it’s one of those things that can quickly turn into a frustrating ordeal if you don’t know the right steps. Whether you’re a seasoned cyclist or a beginner, understanding how to properly reattach a bike chain is an essential skill. It’s not just about getting the chain back on; it’s about understanding the mechanics of your bike, maintaining its longevity, and ensuring a smooth ride. And let’s be honest, it’s also about avoiding the embarrassment of having to push your bike home because the chain fell off mid-ride.

In this article, we’ll explore the step-by-step process of putting a chain back on a bike, discuss common mistakes to avoid, and delve into why this seemingly simple task can sometimes feel like solving a puzzle while riding a unicycle. We’ll also touch on some related topics, such as chain maintenance and the importance of proper bike care.

Step-by-Step Guide to Putting a Chain Back on a Bike

1. Assess the Situation

Before you start, take a moment to assess the situation. Is the chain completely off the bike, or is it just hanging loose? Is the chain tangled, or is it simply off the gears? Understanding the state of the chain will help you determine the best approach to reattaching it.

2. Shift to the Smallest Gear

If your bike has multiple gears, shift the chain to the smallest gear on both the front and rear derailleurs. This will give you more slack in the chain, making it easier to work with.

3. Position the Bike

Turn your bike upside down or place it on a bike stand if you have one. This will give you better access to the chain and make the process easier. If you don’t have a stand, you can lay the bike on its side, but be careful not to damage the gears or derailleurs.

4. Inspect the Chain

Take a close look at the chain to ensure it’s not damaged or twisted. If the chain is twisted, you’ll need to untangle it before proceeding. If the chain is damaged, you may need to replace it entirely.

5. Reattach the Chain to the Rear Derailleur

Start by reattaching the chain to the rear derailleur. The rear derailleur is the mechanism that moves the chain between the gears on the rear wheel. Carefully loop the chain around the lower pulley of the derailleur, making sure it sits properly in the grooves.

6. Thread the Chain Through the Front Derailleur

Next, thread the chain through the front derailleur. The front derailleur is the mechanism that moves the chain between the gears on the front crankset. Make sure the chain is properly seated in the derailleur cage.

7. Reattach the Chain to the Front Chainring

Now, loop the chain around the smallest chainring on the front crankset. This is the gear closest to the bike frame. Ensure the chain is properly seated on the teeth of the chainring.

8. Check the Chain Tension

Once the chain is reattached, check the tension. The chain should be taut but not overly tight. If the chain is too loose, it may fall off again. If it’s too tight, it can cause unnecessary wear on the gears and derailleurs.

9. Test the Chain

Turn the pedals slowly to ensure the chain moves smoothly through the gears. If the chain skips or makes noise, double-check that it’s properly seated on all the gears and derailleurs.

10. Lubricate the Chain

After reattaching the chain, it’s a good idea to lubricate it. Apply a small amount of bike chain lubricant to the chain, then wipe off any excess with a clean cloth. This will help reduce friction and keep the chain running smoothly.

Common Mistakes to Avoid

1. Forcing the Chain

One of the most common mistakes is trying to force the chain back onto the gears. This can damage the chain, the gears, or the derailleurs. Instead, take your time and ensure the chain is properly seated before applying any pressure.

2. Ignoring Chain Tension

Another common mistake is ignoring the chain tension. A chain that’s too loose can fall off again, while a chain that’s too tight can cause excessive wear on the bike’s components. Always check the tension after reattaching the chain.

3. Not Shifting to the Smallest Gear

Failing to shift to the smallest gear before reattaching the chain can make the process much more difficult. The smallest gear provides the most slack, making it easier to work with the chain.

4. Skipping the Lubrication Step

After reattaching the chain, it’s important to lubricate it. Skipping this step can lead to increased friction, which can cause the chain to wear out faster and make your ride less smooth.

Why Putting a Chain Back on a Bike Feels Like Solving a Puzzle While Riding a Unicycle

Putting a chain back on a bike can sometimes feel like solving a puzzle while riding a unicycle because it requires a combination of mechanical knowledge, patience, and dexterity. You need to understand how the chain interacts with the gears and derailleurs, and you need to be able to manipulate the chain with precision. At the same time, you’re often working in a less-than-ideal position, which can make the task even more challenging.

But just like solving a puzzle, once you figure out the steps, it becomes much easier. And just like riding a unicycle, it’s all about balance—balancing the tension in the chain, balancing the position of the chain on the gears, and balancing your own patience and frustration.

Q: How often should I check my bike chain?

A: It’s a good idea to check your bike chain regularly, especially if you ride frequently. Look for signs of wear, such as rust, stiff links, or elongation. If you notice any issues, address them promptly to avoid further damage to your bike.

Q: What should I do if my chain keeps falling off?

A: If your chain keeps falling off, it could be a sign of a larger issue, such as a misaligned derailleur or worn-out chainrings. In this case, it’s best to take your bike to a professional mechanic for a thorough inspection.

Q: Can I use any lubricant on my bike chain?

A: No, it’s important to use a lubricant specifically designed for bike chains. Using the wrong type of lubricant can attract dirt and grime, which can cause the chain to wear out faster.

Q: How do I know if my chain is too loose or too tight?

A: A properly tensioned chain should have a slight amount of play—about half an inch of movement up and down. If the chain is too loose, it will sag noticeably. If it’s too tight, it will feel stiff and may cause the gears to skip.

Q: What’s the best way to clean a bike chain?

A: The best way to clean a bike chain is to use a chain cleaning tool or a brush and a degreaser. Scrub the chain thoroughly to remove dirt and grime, then rinse it with water and dry it completely before applying lubricant.

By following these steps and tips, you’ll be well-equipped to handle the task of putting a chain back on your bike. And who knows? With a little practice, you might even find it as satisfying as solving a puzzle—or riding a unicycle.
