How To Tighten A Bike Chain? Everything You Need To Know!

It doesn’t matter whether you’re an expert cyclist or just a hobbyist, I’m pretty sure you’ve experienced at least for a single time, if not twice, that the chain of your bike appears to be loose while riding.

If you notice the chain seems just a bit lose instead of coming off, you can keep on riding till reaching your final destination.

But when the chain, unfortunately, comes off entirely, it becomes a duty to tighten it in a proper way.

So, if you know how to tighten a bike chain, then congrats! Because you can do it yourself anytime and anywhere using the right tools. But in case you don’t actually know the proper rules and techniques, my writing will definitely help you solve the problem.

Let’s get started right now in order to get all the know-how.

Definition of a Bike Chain

A bike chain is an essential component designed to transfer power from your bike’s pedals to the wheels. Without its assistance, your vehicle is totally useless!

A piece of loose chain decreases efficiency and causes loss of power, which is why tension in the chain of a bike is very important. So, if you see the chain of your bike becomes loose, repairing or fixing it is a “MUST!”

Speaking of chain construction, it’s built with a combination of alloy steel and carbon. This includes nickel-plated bike chains to reduce the possibility of rust build-up.

A loose chain is always risky, so if you want to drive smoothly and safely, the chain should be in better condition.

Why a Bike Chain Becomes Loose?

No need to be worried at all, even if the chain of your well-maintained bike becomes loose; it happens from time to time.

So, it doesn’t mean that you’ll have to change your bike by spending a fortune! Be sure to know the reasons so that you can solve these problems with ease.

Here I’m going to show you 3 common reasons behind a loose chain:

  • Keep in mind, a piece of new chain won’t fit perfectly with your old bike. In that case, let it adjust properly by giving a short period of time.
  • When you see the bottom bracket seems a bit lose, a little tightening will be enough.
  • If you have a bike with single-speed, then you’ll end up with loose chains over time. In that case, it’s essential to know the way of tightening a bike chain.

Is It Really Important To Maintain a Bike Chain on A Regular Basis?

Do you want to keep your bike chain smooth and efficient? If so, then regular lubrication and maintenance are crucial!

Proper lubrication is the key to keeping the chain out of rusting issues. And guess what? It also minimizes the possibility of frequent loosening.

Before you apply any type of lubricant, be sure that the chain is totally free from dirt and such things. Even your high-end lube won’t work at all if the chain of your bike is loaded with unwanted dust, grease, or such kind of things.

How Tight Should the Chain of Your Bike Require to Be?

The chain of your bike requires to be tight enough so that it can smoothly move about ½ inches in each direction.

But if it still slacks even after you follow every single technique of tightening the chain, then probably your bike chain has lost its original shape (expanded over time). It happens when you’re using your old chain for a longer period of time.

When Should I Choose Replacing Instead of Tightening?

Selecting between replacing and tightening depends on the usage. If the bike chain you’re using is quite old and you’re dealing with a loose chain more often, then probably it’s time to buy a new one.

However, sometimes you can tighten it without burning the midnight oil. In that case, I’m going to show you 2 different types of bikes. And the point to be noted – the way of tightening will be different as well depending on the types:

  1. Single-Gear Bikes
  2. Multi-Gear Bikes

Tools Required to Tighten the Chain

Let’s collect some necessary pieces of tools to tighten the bike chain:

  • Socket Wrench
  • Rag
  • Lubricant
  • Bike Stand (Optional)
  • Socket Wrench Adapter
  • Gloves

The Way of Tightening Up a Chain (Single-Speed Bike): Step-by-Step Guide

Without more delays, let me show you everything about tightening up a chain on a single-gear bike. This step-by-step guide will definitely make this job a breeze!

  • Step-1: Flipping The Bike

First things first, be sure to flip the bike right away so that the handlebars and saddle are facing down. This will make your task way too easy when we talk about tightening up the bike chain.

Besides, you can take assistance from bike stands as well. It prevents the handlebars and saddle from accidental scratches.

  • Step-2: Loosening The Tire (Rear)

After putting your bike in a particular position, your next duty is to loosen the nuts of the axle, which holds the rear tire in place. In that case, your socket wrench or axle nut removal will come in handy.

Now, you can adjust the chain tension if the tire seems to be loose.

  • Step-3: Dragging The Tire Back

You can improve the tension on the chain of your bike by dragging the tire (rear). In that case, you won’t have to burn a lot of calories; ensure to do this at a snail’s pace to reduce the possibility of chain damage and breakage.

  • Step-4: Getting The Right Tension

The best way to get the right tension is to see if you’re capable of moving it approximately ½ inches in both directions. If you notice you’re able to move it smoothly, make sure to push back a little more on the tire (rear).

But in case you’ve over-pulled the rear tire, the chain will appear to be extremely tight. Consequently, the pedals can’t turn normally.

Keep in mind, the step is very important, so you’ll have to get it right.

  • Step-5: Tightening The Tire (Rear)

When you see the tension of the chain is established, make sure to tighten every little nut (axle) carefully, for which the tire gets fitted perfectly onto the frame of your bike.

It’s necessary to be careful while tightening the axle nuts using the socket wrench. And of course, the rear tire shouldn’t touch your bike frame as well as the chain, bear in mind.

  • Step-6: Time For Testing!

Since the way of tightening the chain is complete, it’s time for a final checkup. Move on to the chain immediately to see if you can smoothly turn it around ½ inches in both directions or not.

Spinning the tire (rear) will be a good idea to make sure that it has been fitted correctly. Again, confirm that the tire isn’t touching the frame and the chain while moving. That’s it!

The Way of Tightening Up a Chain (Multi-Gear Bike): Step-by-Step Guide

If you have purchased a multi-gear bike, let’s say a mountain bike, it’s necessary to follow this method that’s a bit different when it comes to tightening your bike chain.

So, follow me and let me show you all the nooks and crannies about tightening up a chain of your multi-gear bike:

  • Step-1: Flipping the Bike (Once Again!)

Again, you’ll need to flip your bike. In that case, you have 2 different options to choose from. The bike stand might help you get the job done. On the flip side, you can just rest your bike on its handlebars and saddle.

  • Step-2: Looking for the Derailleur Screw

In almost every multi-gear bike, you’ll notice a little screw on the rear of the derailleur. It should be equipped with the letter “B” printed. Rotating the screw in a clockwise position will be a good decision to enhance the tension on the chain of your bike.

  • Step-3: Accessing the Rear Wheel

When we talk about accessing the wheel (rear) in your bike (multi-gear), it’s important to go through a few steps. Take the brakes off right away from the cable; afterward, you should raise the quick-release lever, and then lifting it will aid in accessing the tire (rear).

  • Step-4: Adjusting the Tire (Rear)

If you’re wondering about improving the tension of your bike chain, make sure to slide the tire (axle) backward. Performing little adjustments will be enough since you’re not going to tighten up the chain at an extreme amount.

So, lower the lever as well as make a little adjustment. Check the chain of your bike out to see if it gets a proper amount of tension or not. In case you’re unhappy with the tension, feel free to repeat the method with the wheel (rear).

  • Step-5: Restoring Order

Before trying to ride, be sure that each and everything is in a perfect position. In this case, confirm that the cable of the brake is properly connected and the release lever is down. I know you definitely won’t use a bike without brakes, right?

Well, now you can spin the tire through your hands to ensure everything is fitted correctly. Also, remember that it’s not touching the chain and frame whilst moving.

VOILA! You’re done! This is how you should tighten your multi-gear bikes in the best way possible. Don’t forget to WEAR GLOVES to keep your hands and fingers away from minor to major accidents. Besides, the rag will also come in handy when we talk about wiping off lube and stubborn dirt.

Efficiency and Maintenance of Bike Chain

We all know that a bike chain plays a significant role in improving the overall performance of your riding, ensuring maximum efficiency as well.

But if you want to maintain efficiency, lubricating the bike chain is crucial. In this case, some bikers suggest using liquid lubes since it offers optimal performance (according to their statement).

In my opinion, liquid lubricants catch more dirt, which is why you’ll have to clean up your bike more often. So, I think using dry lubes will be a wise idea as it evaporates immediately and stays almost clean.

Before applying lubricants, whether it’s dry or wet, ensure to remove the stuck-on dirt from your bike. Using lubes on a dirty chain is the worst idea since it might cause serious problems. So, always clean the chain before using lubes and stuff like that.

Importance of Using Lubes

If you want to maintain the tension in your bike’s gear system, regular lubricating is important. The chain might slack more often when proper lubrication isn’t occurring.

The proper-lubricated chain gives a smooth pedaling and gear-changing operation to a cyclist, ensuring optimal functionality. In addition, it enhances the longevity of the chain of your bike as well.

So, be sure the chain of your bike is free from rust, stuck-on dirt, and such things. Don’t forget to pay attention to the high-end lubes that offer optimum results.

The Easiest Way of Cleaning and Lubing Your Bike Chain

Lubing and cleaning your bike chain isn’t rocket science. However, it’s essential to follow a specific rule so that you can accomplish the task way too smoothly. So, stay focused and keep on reading this step-by-step guide:

  • Step-1: Getting A Rag

Using a particular rag is the key to wiping off the stubborn or stuck-on dirt from the chain of your bike. In that case, pour a wee bit of chain cleanser onto the piece of rag you’ve collected.

  • Step-2: Wiping off The Grease

Now, your duty is to wipe off the grease from your bike chain. But in case you have no cleaning tool, you can take assistance from freshwater to remove the dirt as much as possible.

  • Step-3: Drying The Chain

After washing the bike chain through a cleanser or water, let it get completely dry so that you can apply a certain amount of lube to the chain.

  • Step-4: Time For Applying!

Make sure to utilize the necessary amount of lubricant on the chain. Before applying, it’s better to put on gloves to keep your hands spick-and-span.

  • Step-5: Removing Residual

Applying excessive amounts of lube might create a negative impact on your bike chain. So, ensure to use no more than a couple of drops and wipe off the residual using a piece of rag and cleanser. After that, you can keep on riding without a second thought!

When It Becomes Crucial To Change A Bike Chain?

In a nutshell, you should change or replace your bike chain after cycling every 2000 miles (approximately).

Alongside it, there is another way you can apply; guess what? Well, measure the chain of your bike with the assistance of a ruler.

I prefer starting from the single link pin to each and every complete link. Putting a slight tension might be needed to get the correct measurement.

When it comes down to a new chain, 12 inches with 12 links is ideal. In case you notice that the measurement appears to be a little more, it’s a must to change the chain because it’s already become extremely loose.

So, Is It Really Tough To Tighten A Bike Chain?

If you’re not involved in repairing and fixing jobs, then it might be a bit complicated or time-consuming to tighten the chain of your bike.

Believe it or not, there is no shortcut way of fixing the problems. When you find that the bike chain is loose, whether it’s a derailleur or a fixie, following my above-written methods is the only way to solve your problems.

And if you’re an expert in the world of fixing and replacing bike chains, you can get this job done without much effort, hopefully!

Wrapping Up!

As you know, a chain is an essential part of each and every bike, which is why it requires frequent checkups and extra care. So, if you’re unable to fix the loose chain, my writing on how to tighten a bike chain will definitely help you complete the task within no time.

Lastly, I want to say if you take good care of your bike and every little part of it, your vehicle will last a bit longer; I’m pretty sure as eggs are eggs!
